Home Theater Soundproofing Using Acoustic Panels

Home Theater Soundproofing Using Acoustic Panels

 

Owning a system for home theater definitely increases the enjoyment of viewing a movie. Even when majority of people like hearing movies set at reasonable sound levels, the resulting noise can certainly be bothersome for the neighbors. This is the reason it is vital for owners of home theater to utilize high-quality soundproofing in their homes to evade complaints from the vicinity.

 

It is hard to soundproof bass waves and requires professional skill to entirely soundproof a room. For soundproofing a room the optimum way to is to build a floating room in which the walls, ceiling, and floors are isolated structurally from the remaining part of the building. This makes it entirely soundproof. However that is a very costly procedure.

 

A relatively cheap option for soundproofing would be to utilize acoustic panels for soundproofing a room. Acoustic engineers utilize a combination of diffusion and absorption techniques for making a room soundproof. Utilization of these is done to take in sound energy in addition to distribute the essential sound waves uniformly across the room in order that unnecessary noise is removed. By nature, acoustic panels are porous and when waves of sound transmit through them, trapping of the waves take place and the sound is suppressed. Hence, it is very efficient for soundproofing walls.

 

Acoustic panels assist in lessening vibrations of sound by regulating stray waves called ‘room modes’, ‘flutter echoes’, and remaining vibrations that could result from a room’s construction and proportions. The material for soundproofing generally utilized for acoustic panels is panes made of fiberglass in simple frames, which take in the sound. Also these panels are known as ‘bass traps’ since they trap frequencies of bass and stop spreading of the same. For soundproofing walls and soundproofing ceiling, fabrics, acoustic diffusers, and foam could also be utilized.

 

Usually floor soundproofing is not required in the instance acoustic panels are utilized. However as a preventive measure, utilizing carpets are usually recommended by experts of soundproofing. You can fit acoustic panels anyplace in a room based on what looks attractive visually. These days, acoustic panels that are attractively patterned are also accessible, which provide the twin purpose of soundproofing of home in addition to that of wallpaper. Hence, if somebody is thinking regarding enjoying soundtracks of movie and music on his home theater, utilizing the correct material for soundproofing becomes the perfect way for doing it devoid of causing inconvenience to the neighbors.

Acoustical Coating – Part 2: Selection of Acoustical Coating and Testing

Acoustical Coating – Part 2: Selection of Acoustical Coating and Testing

As mentioned in Part 1 already, once you have applied the material on to the surface, it may be too late to realize that the particular coating is not a real acoustical coating. Therefore the evaluation must be carried out well before buying the item and not after that. Do not get carried away by a brochure or a label printed at a local printing press which may claim many things but that is not to be taken as a  basis for buying an item, but as the buyer you must be very discriminating. After all, the printing company will print out whatever copy that is supplied to them.

Genuine manufacturers of acoustical coating will get their products tested at independent laboratories for ensuring that (1) from the point of view of product development, the performance of the product is as expected, and (2) that it is as per the claims put forward by them in their publicity literature. These laboratories test the materials as per the relevant ASTM test and since they are autonomous bodies, the test data given out by them are impartial. In every country there are approved accreditation laboratories whose reputations are highly regarded because of their independent testing protocols.

Suppose the product manufacturer is able to produce a reasonably latest test certificate that says that the using of their product shows no negative result on the quality of sound absorption by the surface material, it may be safely decided that it can be purchased. But it must be made sure that the testing is carried out repeatedly only recently, because there can be occasional modifications of formulas particularly during tougher economic situations, when there is a rise in the cost of quality raw materials.

A fire test is yet another test normally carried out to check an acoustical coating. The test will check the speed at which, in case of a fire, the flame would spread when the surface is applied with this acoustic coating.  And also, it will test how much smoke is developed when that surface material is burning. This test is a very important consideration while choosing a product for acoustic coating because more people die due to inhalation of the smoke than due to heat.

If the acoustical coating is of a better quality, the flame spreads slower and lesser smoke is produced. That is the reason for most top rated acoustical coatings carrying a fire resistance rating of Class A.

And a final remark about what the testing by an independent laboratory means to approval of products. Independent laboratories issue a product approval rating. If the laboratory issues an “approved” classification, it goes to prove that they have done more than just testing the material. It indicates that they will pay periodic visits to the facility that is manufacturing the product for confirming that there is consistency in the formulation and that all procedures of quality control are followed.

Therefore, before selecting an acoustical coating to be used on an acoustical surface, do check to ensure if possible that an independent laboratory has tested the same and has issued an “approved” classification for the product.

 

Acoustic Ceiling Systems

Acoustic Ceiling Systems

The scientific aspect of sound and the significance of acoustics have always been, and unfortunately still are, greatly underrated disciplines within the premises of several industries that are still dependent on their own in-house expertise to cope up with issues arising out of noise and bad acoustics. If only the architects and property developers alike had paid sufficient attention to the acoustic quality of buildings of industries and living areas and appreciated the enormous influence of acoustics has on them, things would have much easier later on for the end users.

Several people still seem think that it is necessary to limit the control of the discipline of audiology and acoustic environments only to areas of commonly known applications like concert halls and music venues, for instance. However, unknown to ourselves we are all exposed to the ill-effects of the acoustic environment around us in our everyday life, and to speak generally, oblivious to the manner in which this can disturb the levels of our concentration, productivity, and also mood.

Effect of environmental acoustics

As per a 2004 study on the influence of various acoustic environments on the patients and members of staff inside a healthcare setting, better room acoustics considerably improved the psychosocial work atmosphere. It was also noticed that acoustic could have had some more beneficial impact on staff turnover, level of patient care, and also possible medical errors. The above may be only one example of the manner in which your environmental acoustics can seriously affect you and the people around you. You can find several more proof to indicate a definite link between acoustics and psychosocial wellbeing. Employers still have not fully realized the beneficial impact that a professionally managed acoustic environment can have on their staff and also on the visitors as well as contractors.

Benefits of acoustic ceiling systems

Even though there exist quite a number methods of regulating environmental acoustics, the acoustic ceiling system happens to be the simplest one among them with maximum effect.

Acoustic ceiling systems have considerable positive impact on sound by improving the speech intelligibility level and they also provide good protection from unwanted external or intrusive sounds. When we consider the question of design and structure of acoustic ceiling systems, two main factors that come up indicate effectiveness are sound absorption levels and sound insulation.

The absorption of sound help to reduce not only the total sound levels, but also those specific sound frequencies that are not easy to be heard at specific periods of time and that have even been proved to cause irritability and also in few instances aggressive behavior. Acoustic ceiling systems are helpful in reducing sound levels through absorption of sound and limiting room reverberations. Whereas the purpose of sound insulation is to protect the internal occupants of an area against unwelcome external noise.

Theater Seating Contractors for Large Venues

Theater Seating for Large Venues

 

You may be in-charge of commercial cinema seating installation for a venue like a church, a stadium or a performing arts center. Or, your corporation could have facilities for conference and remaining areas requiring seating of high-quality.

 

A successful auditorium seating or theater seating decision will yield profits by way of savings, performance, and peace-of-mind for years coming up.

 

Consider few of these “optimum practices” as the process of selection unfolds:

 

Seating in Bigger Venues

 

Irrespective of how many theater seats are required, due carefulness must be exercised in analyzing techniques of construction, customizability and warranties. But, unlike buyers of home theater chair, for instance, commercial buyers won’t usually consider ultra-luxurious theater chairs. Instead, ease-of-maintenance and upfront costs will be vital considerations. Hence, massaging recliners having exotic wood trims won’t be selected. The expenditure and the lesser durability of residential theater seating as such would not be justifiable.

 

Explore Opportunity for Volume Discount

 

Frequently a commercial client will spend less for each chair because he orders in bulk. For example, consider cinema seating installation. A classic theater could require about 225 theater chairs for each screen. In many cinemas, numerous screens are common, and 8-10 or additional screens are uncommon. Hence, commercial clients usually purchase in volume, and they generally buy only one style. This preserves brand consistency making future changes easier to complete.

 

Corporate and remaining volume buyers should always attend to the most important factor. Purchases in bulk justify volume discounts calculated carefully. Hence, the list prices of different options for theater seating or cinema seating installation must only be a beginning point. All seat styles cannot be discounted in the same way, so it is important to carefully work with a representative of vendor to ascertain volume discounts for particular kinds of theater seats. Finally, features, price, and warranty should all be considered to determine which the incredibly best deal for your situation is.

 

Optimizing Comfort

 

It is factual that a commercial client is not probable to choose luxuries like adjustable headrests and power recliners. However, comfort is yet a critical factor. Customers will more probably return if they have stayed comfortable through a two-hour theatrical performance or film. Good lumbar support and ergonomic designs are usually necessary components. For instance, a “pub-style” or tufted seat back will provide additional lumber support. Also rockers let patrons to comfortably shift during extended shows and events. In majority of cases, fold-up arms and cup holders will be integrated to improve the experience of customer.

 

Key Considerations for Maintenance

 

Auditorium seating and theater seats or cinema seats in public locations will usually be subjected to rigorous utility. For instance, cleaning costs must be carefully considered when making a decision to choose either microfiber upholstery or regular fabric.

 

Saving a small amount upfront could become irrelevant if repair and cleaning costs boost in the upcoming years. Work closely with a commercial supplier having experience to better find out which seating could truly endure the test of time.

Benefits of Using a Home Cinema Designer

The Benefits of Using a Home Cinema Designer

Designing a room for home cinema utilizes a diverse skill set than our standard multi-room installations of audio and video. Home cinemas function by being pleasant to the eye and having a good atmosphere. When you install entire house systems you are seldom involved in separate room designs – you might install TV and in-ceiling speakers however you would not get involved in carpet styles and paint finishes. You might come closest to adapting a present furniture piece to accommodate a plasma lift or creating lighting scenes for the initial time.

In a room for home cinema, things such as the flooring type and the wall finish have a big impact on the end product quality both in acoustic terms and the impression about the room created in your mind that is difficult to express. This feeling about the room summarizes the excitement to some extent of visiting the cinema theater and the suspense involved in sitting and watching the latest keenly awaited blockbuster film. Utilizing dark colors in the room can lessen visual reflections, with dimmed lights; make sure the screen for home cinema is the item of most importance in the room. Thick carpet creates a true sense of luxury and also adds to the aesthetics a room has – taking in unnecessary standing waves and lessening sound leakage to neighboring rooms. Seating for home cinema must be selected for accommodating the owner – it’s likely to obtain a large range of finishes in fabric, leather and options like embroidered initials or contrast stitching can actually make clearly understood the custom-made unique feel the room has. Daybeds can be an alternative to conventional seating for home cinema providing the ultimate location for relaxing and spending time with the entire family.

As per reports from many customers, spending quality time with the family is possibly the most vital aspect of home cinema – kids are going to love the very fact that they can have the actual experience of movie at home. Also parents of elder children take pleasure in the fact that their kids with friends spend time in the protection of your house. Moreover if you add a DVD server to your home theater it will make certain that kids can access only those films that you would like them to watch, that is, films having ratings for ‘elder kids only’ cannot be seen except when you enter the secret pin, and by making use of the view list of the films you can also select the films to be viewed by length making sure that there is enough time to watch the full movie prior to bed time.

Acoustical Surfaces design and install the best rooms for home cinema, having solutions for a  variety of budgets.

There are many tools accessible these days that assist you achieve this and one among them is acoustic panels.

You can customize these panels to specifications of room and hang them from walls or ceilings. Panels can differ in thickness however almost all carry out the same function, that is absorb sound. A panel of four inch thickness will demonstrate a performance similar to an acoustic panel of two inch thickness when utilized in a room with sounds of high frequency.

Majority of the most modern panels utilized for sound absorption are available in various exciting colors. Now you can select a color complementing the aesthetic look your room has. Color does not have much significance in ascertaining how an acoustic panel performs however it can immediately enhance the appearance of the room where it is utilized.

Since these panels are designed to absorb sound, on the surface they have an exceptional fabric. Every time waves of sound enter into your room, they rebound on hard surface like walls and produce noise. Suppose you want to benefit from a silent space, you have to evade distractions from loud conversations and traffic sounds. It is here that these panels are useful.

Few of the most recent panels also are available in a range of exclusive designs that make your room not only appear good however sound excellent also. You can place the panels at appropriate places in your room. This will avert the sound waves from rebounding from the walls. For achieving the result that is desired you will require fewer panels suppose you position them properly.

Sound is absorbed by the fabric on the panel surface. This helps you to remove noise in an excellent looking room. These panels can really help you to regulate the sound movement in your room. Most significantly, you can only hear the sound you desire as unwanted sound noise and annoying echoes will no longer damage your hearing experience.

Suppose you would like to know where these helpful panels can be utilized, there is a broad range of choices for you to select from. These products can be utilized in rooms utilized for video conference, teleconference, radio broadcast and music recording. Also, these panels can be placed in an auditorium or where your system of home theater is kept.

Classroom Acoustics and ANSI Standard  

ANSI Standard S 12.60 on Classroom Acoustics

On any given day, several thousand students throughout the country do not comprehend even 25 to 30 percent of the subjects that are being taught in classrooms. What happens is that too much reverberation and noise in a classroom affects a student’s capacity to listen to what is being said by their teacher.

Before we review the standard under discussion, it’s imperative to know the characteristics of sound encountered in the classroom that influences a student’s capability to listen and learn.

Direct Sound Control

The sound carrying the teacher’s voice traveling from the teacher directly to the student is known as direct sound. This is most beneficial as far as speech intelligibility is concerned because it is not hindered by any object inside the space, making it distinct and clear.

Reflected Sound

A sound that is reflected takes more time to arrive at the listener’s station compared to direct sound for the reason that its route to the listener is lengthier. Reflected sound is beneficial or otherwise depending on the delay in time.

Reverberation Time

The general effect of sound when it gets reflected in a room is known as reverberation, and the actual time taken by the reflected sound to fade out and become inaudible is termed as reverberation time. The shorter the reverberation time the better is speech intelligibility.

Background Noise

Any kind of sound produced outside the school building, like playground activity, planes and traffic can be said to be background noise. It usually enters the classroom through the windows. Inside the building, a system like H V A C and corridor noise can also produce background noise.

The New ANSI Standard

ANSI Standard S12.60 is meant for classroom acoustics and deals with the issues of both background noise and reverberation time and the consequence on intelligibility of speech and specifies the maximum allowable levels on them.

As per the standard, the maximum permissible reverberation time in a furnished, unoccupied classroom having a volume below 10,000 cubic feet should be 0.6 seconds, and for a room having volume from 10,000 to 20,000 cubic feet it should be 0.7 seconds. For background noise the permissible level of sound allowed for the same classroom should not be more than 35 decibels (dBA).

The acoustical performance norms and design conditions specified by the standard is applicable right from the design and construction stages to all new learning spaces and classrooms of small and medium sizes, and, also to reconstruction and design of renovation and if practical, to the design and reconstruction of refurbished spaces as well.

Presently, the ANSI standard is not compulsory unless enforced by a regulation, code or ordinance. But, the school administration may require that the standard be complied with as per their building documents for newly constructed schools. The ANSI S 12.60 Standard is freely downloadable online.

How to Soundproof your House With Acoustic Products and Materials

This is a continuation of the previous part titled ‘How to Soundproof your House

Is it worthwhile to soundproof?

For even improved results, Sound Blocker Quilt can be used alternatively however this product has to be fitted to the stud or joists while the A M W is only a loose fit.  

When covering floors and ceilings with many Acoustic Plasterboard layers, excellent sound control levels can be attained. But, it is vital that all soundproofing is correctly installed and always it is best to contact experts before beginning to soundproof. Not only could this save you money however could also save you time installing either incorrectly or the wrong insulation.

A usual mistake that many make is using King-span or polystyrene type insulation in the wrong belief that these soundproofing materials are good however they are not. These Acoustic materials are thermal insulators and have very less or no acoustic value. At this point you can get help from experts for the right specific advice suppose you are considering soundproofing any structure.

For outside noise, irrespective of your home construction, doors and windows will let in the majority of noise followed by lofts and roofs. Sufficient loft insulation will absorb some noise coming via the roof and assist soundproof this area.

Now for doors and windows. These areas will allow in the most sound. Single glazed windows are inherently a sound blocker however offer very less in the method of soundproofing. For soundproofing these additional panes are needed and suppose they are denser will more than twofold the value of insulation. Triple glazing is great and if installation of these is done with varied thicknesses of glass unevenly spaced most outside noise will be prevented. With glazing, it is vital to ensure sealing of all the panes and no gaps allowing leakage of noise. Doors are slightly different since it is not practical doubling or tripling these up except in commercial premises. The requirement though is in fact a heavy solid door fitted with seals for ensuring an airtight seal on closing.

All materials utilized for soundproofing a room will have changeable effectiveness at either absorbing or blocking noise. Called S T C ratings (Sound Transmission Class) the soundproofing will be more effective if these ratings are higher. Majority of usual materials in the home will have a rating of S T C even if it is not intended for a specific sound control purpose like masonry walls, windows, and carpets. Insulation intended specifically for control of noise will have a quantified S T C rating and also additional qualities for making them effectively insulate against noise pollution.

 

Basics of Home Theater Installation are Changing With Acoustical Products

Basics of Home Theater Installation are Changing, While Remaining Constant

You may find it confusing, but consumer electronics is not easy to understand because changes keep happening continuously. There may also be a lot of debates on what should be the order of priority of installation of components of home theater. You may hope that the answer will be simple, but the rapidly changing technology does not make it any easier.

Humans have different preferences, when it is a question of sensations. Few may prefer the audio, and think that the sound quality should be given more importance, while some others prefer the graphics, and show a liking for images.

You have to follow some steps to achieve the best outcome, when you think of buying the speakers during the installation of the home theater or even before it is considered. In case you prefer the visual, think of adding a projector, but before that make sure that the room selected for the home theater is suitable for installing a projector. The factor that decides this will be the range of throw. This is the distance between the projector and the screen. The throw range of a projector is given in the specification and the room selected should be having the minimum range specified.

When the installation is being planned, the projectors should not be close to windows and doors. It should be positioned at an angle of 90 degrees to all windows and doors. If your budget permits you may like to have raised seating, because then you can find a very suitable place to hide sub woofers.

If you prefer the audio, you should spend some time making sure that the speakers are placed properly. As per normal practice, there should be a right front, left front and center speaker. At the rear there will be a left rear, right rear, and the subwoofer. If it is the 7.1 system an extra surround sound is added at the right and left.

Though people think that expensive speakers produce the better sound quality, insulation, features and characteristics of the room together contribute to the quality of sound. The speaker positioning should be such that it provides optimum quality of sound.

The speaker height is very important, because if the height is too low, there will be conflict of signals as it will interfere with the signals of the subwoofer. Most part of the conversations in the movies is conveyed through the middle channel; therefore it is advisable to have the middle speaker placed right above or below the display monitor or the screen.

Many advantages and reasons for having wireless devices

You have wireless system of speakers offered as part of home theater installation, but there is difference of opinion whether the quality of sound is any different with wireless systems. Unless you have practical problems, it is ideal to locate all parts in one room, but when it becomes impractical, infra-red remote control may be useful.

 

Achieving Effective Acoustics in Hospitals Introduction and Absorb Noise

sound proofing Acoustical Soundproofing Products

Achieving Effective Acoustics in Hospitals – Introduction and Absorb Noise

In hospitals noise is a problem that is well-documented. Sources comprise of staff, patients, and visitors talking, alarms, televisions, carts, medical equipment, mechanical systems, doors, and more.

For patients these noise cause more than only irritation. Actually, side effects like quickened heart rate, increased metabolism, and high blood pressure have led few researchers to come to the conclusion that noise could even slow their rates of recovery.

One among its most serious affects is stopping patients from obtaining the rest they require. While for all disruptions in sleep noise is not to blame, it makes significant contribution. By intervening with onset, upsetting normal patterns and causing awakenings, noise lessens both the quality and quantity of their sleep. Deprivation of sleep can deteriorate the immune system and result in delirium, agitation, and reduced tolerance to pain. Therefore, patients will have to make nursing calls more frequently and request for sleep and pain medication, and remain longer in the hospital.

However noise affects not only the patients. Though you could think that over time staff can get less receptive to these noise disruptions, no one can completely tune them out since our senses are intended to detect such alterations in our environment. For caregivers noise makes it hard to concentrate, causing fatigue and stress. Their pace of work lessens and more errors are made by them, possibly affecting the care quality.

In health care the importance of acoustics is evident from the present available number of resources on this subject. Since the 1990s measures have been taken to deal with still another concern of acoustics: speech privacy. A set of methods should be used to address speech and noise privacy issues since no single material or strategy can deal with all pathways of sound transmission.

Acoustic professionals have developed the three-tiered approach called as the ABC Rule, which represents Absorb, Block and Cover. For hospitals the challenge is to apply this rule in a way not compromising sanitation or access to patients by caregivers.

Absorb Noise        

Materials that are absorptive lessen the energy of noises reflecting from their surfaces again into the space. Doing so, they cut down the time noises persist and the amount of distance they travel, lessening overall echoing and volumes.

Since in a facility the ceiling is generally the largest undisturbed surface, utilizing a tile with good sound absorption is important. Hanging of absorptive wall panels must be done specifically in important reflective locations and on huge vertical surfaces, like corridors. Suppose needed, a thin impervious or antimicrobial film can be fitted to absorptive materials for maintaining wash ability and sterility without considerably affecting performance.

The impact noises that footfall cause is disruptive and loud, and very hard to tackle once created. Hence, resilient underlays and soft flooring must be used, at minimum in areas with high traffic.
