Home Theater Accessories – Changing The Mood

Home Theater Accessories – Changing The Mood

 

Home theater accessories make best use of the function of your system for home entertainment and improve their general performance and can decide the mood your room has. A very rough definition of a home theater is an all-encompassing video and audio experience. That usually requires a large screen and surround sound-it is that easy. A large screen can be anything in surplus of 30 inches. No matter which thing under that actually is not capable of encompassing you in the event.

 

Also a large screen must be a widescreen whose shape is more rectangular like that of several high-definition televisions (HDTVs) available today. Also these models will enable you view movies more widescreen devoid of those frustrating black bars squeezing the viewing area.

 

DVDO is one among the newest technologies in systems for entertainment. It assists create a picture perfect lucidity because it has a converter for picture that transforms normal picture to picture of high definition. Also DVDO produces pictures that are laser sharp in addition to a very clear sound.

 

Cables that are High Definition Multimedia Interface (HDMI) are one more necessary factor of the theater. Cables such as these are produced from electrolytic copper conductors having gold plated contacts. This makes sure that through the data transmission, nothing is lost in the procedure. Also HDMI connects the accessories of home theater to additional devices like digital media player and gaming consoles.

 

If you would like to fix your flat TV panel on the wall or position it hundred meters distant from the source of video, then you require special fiber adapter for optical cable. It is good to have this accessory particularly if there are several people viewing because by positioning the flat screen many feet distant from the origin, the image will turn out to be larger.

 

Also you need accessories such connectors, bulk wires, plates and panels for your AV requirement. There are several quality wires and cables in the market known for their excellent performance. You can find them through browsing the internet or through friends already using such items. So as to provide continuous, smooth data flow from the theater to different devices, you require to have coaxial cables of high definition of proven quality.

 

Also for your home system acoustics are required as accessories for providing a harmonious symphony to the complete home. You can also find good attractive mid wall panels in the market to add as extra accessories to your system for entertainment since they take in sound so well and presents the theater experience an entire new meaning.

Fire Resistant Gypsum Ceiling Panels

Fire Resistant Gypsum Ceiling Panels

 

Ceiling panels with gypsum lay-in are tiles that are utilized in food processing areas or kitchens, warehouses, utility rooms, storage areas or any other soffit or interior ceilings that are attractive and economical instead of acoustical in performance. They are reinforced by hanging ceiling grids.

 

These gypsum panels are long-lasting and provide sanitation to the areas of food processing. Usually they are laminated with vinyl to seal out moisture, dirt and odors. The surfaces of vinyl are embossed and are remarkably stain resistant. Also they can withstand frequent washings. Efficiency of lighting is maximized since they have exceptionally reflective surfaces.

 

With the finish of laminated vinyl, no more need is there for further finishing. However if a client so wishes, it is suggested using two coats of semi-shiny or alkyd latex enamel. Also, an oil primer can be utilized then coated with flat latex or oil paint. Two coats of flat oil paint also can be used.

 

The panels can be cut easily and can fit in ordinary suspended ceiling grids. They can be easily washed. Rubbing the surface lightly with damp sponge or cloth or using detergent or soap will remove marks and dirt. Steel wool and intense organic solvent cleaners are not suggested to utilize in cleaning the boards.

 

Detergents, 10% Ammonia, 5% Nitric Acid, Oleic Acid, Ethanol, 10% Hydrochloric Acid, Bleach, Hydrogen Peroxide, Carbon Tetrachloride, and Port Wine will not be effective on the gypsum panel although the panels come into contact with these chemicals for 24 hours. Effortlessly they can be washed with water and soap. 10% Citric Acid, 10% Sodium Hydroxide, Ketchup, Lemon Juice, Mayonnaise, Coffee, Tea, Milk, Cooking oil, Crayon, Trisodium Phosphate, Vinegar and Mustard will also not be effective on the gypsum board even on exposure to these chemicals for 24 hours. Marks from pencil will leave an extremely light stain however. Exposure to acetone for 24 hours subsequently washed with water and soap will give a shiny finish to the panels.

 

Ceiling panels with gypsum lay-in must not be utilized in areas that have direct exposure to water. They must also not be utilized in shower dressing rooms, swimming pools, and in areas having high moisture or humidity. Backload must be restricted to 0.5 pounds for each square foot. Unheated or enclosed spaces over the ceiling panels must be correctly ventilated. Hold down clips or retainers should be supplied in installations where sudden air pressure or wind change may lift the panels. Utilize only an approved hanging system for external utility when being installed outside.

 

The gypsum boards are available in 5/8″ and 1/2″ thickness with type X fire rating. A type X fire rating implies that the board has a lowest fire rating of 1 hour that is the requirement of majority of building codes. It is more resistant to fire and more costly than the ordinary boards. Usually Fire rated boards are needed in living room areas and in such areas where there is risk of fire.

10 Soundproofing Material Myths

10 Soundproofing Material Myths

 

Soundproofing is a domain of technical expertise very steeped in folklore, myth, and legend. For that reason, in this article 10 domestic myths for soundproofing material are given:

 

1) Egg Boxes

 

Perhaps one among the most recommended alternatives to correct domestic soundproofing, it is a dishonor that subsequent to spending the essential time and effort to accumulate enough egg boxes for covering a room you would discover it has slight or no properties of soundproofing whatsoever.

 

2) Dark Paint

 

Even as dark paint will take in additional light than say, dimmer paint, it won’t provide any insulation from sound and make the room appear dingier and smaller too.

 

3) Particle Board or Plywood Panels

 

Decorated properly they can put in a certain chintzy charm of 70’s to a room, though unfortunately wood is likely to be a relatively good sound transmitter – hence its recognition in the making of musical instruments.

 

4) Old Mattresses

 

Fixed to your walls with edges properly sealed and thoroughly butted jointly these can really be reasonably effective. But, specifying the downsides, such as moisture retention, odors, bedbugs, mould, and probable rodent infestations it is not really worth considering.

 

5) Foam Rubber

 

Similar to that utilized in the making of rubber mattresses, or definitely utilizing rubber mattresses themselves can be reasonably a superior material for sound insulation, it is just regrettable that besides costing essentially the same sum as suitable products for soundproofing, it will deteriorate to mush with time and presents an immense fire hazard.

 

6) Hay Bales

 

These can make great sound insulating units, but they will deteriorate rather quickly, catch fire, and present cattle, horses and small animals with a good supply of both bedding material and food.

 

7) Cavity Wall / Cellulose Insulation

 

Will most certainly help to avert the heat transfer amidst the walls, and comes highly suggested if you are looking to better the energy efficiency of your home, the overall enhancement in soundproofing will be trivial at best.

 

8) Carpets

 

Carpets will take in more sound than wood or tiled floors, hence the room itself will return less sound; though the sound transmission via the floor will stay somewhat much the same.

 

9) Rubber Floor Mats

 

Even as rubber when utilized correctly can offer good characteristics of soundproofing, just a rubber mat thrown on the floor will not do much to avert the sound transmission.

 

10) Fiberglass Insulation

 

Like the cavity wall / cellulose insulation, adding fiberglass insulation will definitely help your property preserve heat and boost its energy efficiency; regrettably it will do very less to better your acoustic insulation.

Making Your Home Theater Sound Better – Part 2: Absorption, Reflections

Making Your Home Theater Sound Better – Part 2: Absorption, Reflections

Reflections, Absorption

A room filled with solid reflective surfaces is bound to generate a sound full of echo and some amount of harshness, as against the dull sound reflected from soft and absorptive surfaces. Take the case of a room having surfaces covered with processed wood, gypsum partitions, ceramic tile and concrete ceilings. This type of surface is perfect if it is reflectivity and echo that you want but is not suitable for intelligible dialog and music with full-bandwidth. With the increase of every decibel additional echo and reverberation are created. With this type of a room to start with, start adding soft furnishings and any material with surfaces, even at random, you can feel the difference immediately as you do so. It is therefore clear that by adding some simple mathematical approach and acoustic theories you can successfully obtain a balanced sound.

Evidently, achieving optimum results means that the design of your home theater should balance the room surfaces, and this needs the addition of sound absorption. This can be achieved by preventing the reflections of noise and controlling reverberation. For accomplishing this you may use acoustic panels, upholstered furniture, carpets and freestanding or mounted soundboards. Naturally, balancing means not just putting up hard as well as soft surfaces in the space, it is also important to position them with respect to the placement of speakers. An appealing general home theater sound is the result of a blend of surfaces, positions, reflection and absorption.

Rules of thumb

These are general rules that may help, but every sound system and room is an exclusive combination of different elements. Begin with general treatments and carefully proceed to additional specific treatments for your room. In case you are not familiar with making calculations of standing waves or balancing acoustic basics, do get someone to help. Since you are spending so much for your system you have the responsibility to your family and to yourself to ensure that everything is done the right way. Below are some tips:

  • Lay carpets in the space between the listeners and the front speakers for receiving the foremost reflective sounds.
  • Have acoustical curtains and/or wall paneling close to front speakers.
  • Avoid painting acoustic panels, as it makes it more reflective.
  • Soft sofas and cushions absorb echo.
  • Ideally, the ceiling should have a hard surface so that it carries sound to and fro and helps diffuse the surround signals.
  • On an average home theater design should provide minimum of 35% of the overall surface area of room for absorption and the maximum absorptive surfaces should occupy the first half.
  • When the rear of the theater has more reflective surfaces, there is better diffusion of sound (particularly the surround signals) from the speakers at the rear.

 

You may have to experiment by positioning the soft furnishings in different spots in the room. Use decibel meters etc., to help you in fine-tuning your room, but again, if you are not familiar with the procedures, get some help so that you save time and money.

 

Know In Depth About Soundproofing

Know In Depth About Soundproofing

There are so many different methods that are available for you to carry out the soundproofing of your surroundings. The prices may show some inconsistency based on the extent of sound you plan to block and magnitude of the area you want to cover. There are several people who today want to have soundproofing done to their environment. This may include just one room, a complete building or home. Some others want it so that they can shut out the city noise. Yet some other people want to do soundproofing so that they can block the sound coming from their music room or home theater. Some people have problem with noise from their noisy neighbors and want to block it out.  Whatever may your reasons be, soundproofing may be the answer to ensure a peaceful environment. Then, we should examine what soundproofing really is.

Take the right advice before carrying out Soundproofing

If the source of your noise is in a new room and if you would like it to remain that way, you have to raise the sound transmission insulation levels of the materials that are used as partitions dividing the rooms. Products contributing to the increase of the transmission level (TL) of a room partition are classified using a sound transmission rating. You must be very alert when selecting a soundproofing product that does not give you its STC rating in case you are planning to increase your present TL.

Foams used for soundproofing are also usually misrepresented. If you want to increase the transmission level of a partition wall, you need to add to its mass. Spray-on material and closed cell foam will not be enough.

In most commercial buildings and residences floors and walls are supported by an interior structure of steel and wood joists or studs and are further covered using some type of hard sheeting similar to particle board flooring or drywall, which leaves an air gap between the walls, and ceilings and floors. This air space helps in the easy transmission of sound waves having hardly any solid mass so that the sound can vibrate through or slow down its rate of transfer. There are many methods used to slow down the rate of transfer of sound waves. Of this one most popular method is to reduce the speed of the sound waves by insulating the wall, ceiling or floor using any one of the many types of insulation. Though this may help to slow down the rate of transfer of the vibrations of sound via the air space, it can do nothing to stop the sound that is being transmitted through studs, joists, drywall, or flooring.

Building, Design for Sound and Acoustics, Part 2, Understanding the Basics of Sound

Building, Design for Sound and Acoustics, Part 2, Understanding the Basics of Sound

 

This is a continuation of the previous part titled ‘Building, Design for Sound and Acoustics, Understanding the Basics of Sound – Part 1’.

 

Quick Point # 2 (continued)

 

The Frequency Scale

 

Every sound creates a wave at a quantifiable frequency. Let us utilize music as a reference point.

 

In the musical scale every note creates a sound wave at an accurate measurable frequency. This is known as the primary frequency. The primary frequencies are segregated into three major groups.

 

1) Bass frequencies 20 Hz – 250 Hz

2) Frequencies in mid range 250 Hz – 2,000 Hz

3) Treble frequencies 2,000 Hz – 20,000 Hz

 

The upper treble and mid range frequencies are of short length and have less sound energy. Their energy will be lost quickly making them simpler to deal with considering room soundproofing and acoustics. The low frequencies (20-125K) of bass are much lengthier and have more sound energy. This energy is carried by low frequencies for long distances. This makes these frequencies more appropriate to room soundproofing and acoustics. Frequencies at lower range play a main role in both sound quality and room acoustics by creation of standing waves (room modes). Waves such as these color or distort the sound in the room creating an adverse effect on quality of audio. The appropriate range of frequencies of standing wave in room acoustics will be between 20 Hz and 300 Hz.

 

Quick Point # 3

 

1) As per studies majority of the utilizable sound information for humans lies in the range of 300 Hz to 4,000 Hz.

 

2) Our hearing has less sensitivity to low frequencies. For hearing these frequencies we need increased levels of volume. When there is a rise in the sound frequency our sensitivity increases.

 

3) With the utility of your stereo hearing (2 ears) you can accurately find the origin of the sound. By calculation of the delay in the interval of times the sound arrives at each ear your brain computes where the source is located.

 

4) You can filter frequencies and concentrate on what you would like to hear. You can focus on the violins over the remaining orchestra if you prefer or recognize the cry of your baby in the room from other babies.

 

Frequencies and Harmonics

 

The Harmonics of the basic frequency give each sound or instrument its own specific tonal quality. It is the harmonics making a Saxophone sound just as a Saxophone or a flute sound just as a flute even while they are creating the same frequency tone. In this article harmonics will be mentioned about but focus is mainly on the basic frequencies. A tone creates a basic frequency and that frequency in multiples is known as harmonics.

 

Quick Point # 4

 

We hear sounds that are a combination of basic frequencies and their harmonics.

 

Taking light as an instance, while walking outside sunlight is seen as colorless or white. On viewing through a prism you see combination of all the colors for making the light that can be seen. Sound works in almost the same manner. You do not hear the individual frequencies however what you hear is the total sum of the harmonics and frequencies blending together for creating your own personal symphonies.

 

Restaurant Acoustics

Restaurant Acoustics

Have you at any time been within a packed restaurant seated at a table with your girlfriend or wife only to realize that you couldn’t hear a word said by her since in the restaurant acoustics was very poor? Majority of restaurants use hard surface areas all through for the purpose of easy, clean and healthy maintenance of the establishment. The issue with all the clean rigid surfaces is that the sound is reflected by them. That is to say, the sound rebounds around the room. This makes it hard to understand what is being said by the other person at your table, however rather clearly hearing the lady talking at a distance of 5 tables from you. Generally restaurant acoustics are awful.

 

There is loss of business in several restaurants since they do not know basics about acoustics.  Several things are there that managers and restaurant owners can do for making the room a lot more pleasing for their patrons. These areas for dining require to be treated acoustically or absorbent materials are required to take in the noise that is reflective in the restaurant.

 

When a new restaurant is furnished, it is invariably best to add booth seating and fabric covered chairs since fabrics take in the sound. The same applies to lounge chairs, bar stools and couches. Whenever possible utilize fabric covered furnishings.

 

Here is a helpful trick for adjusting the acoustics a restaurant has. There is a product in the market called Echo Barrier. It provides superior acoustic performance and can be easily installed. It has unique roll-up design for transportation and compact storage. It is fire retardant. It doubles or triples up for noise ‘hot spots’. Here is the trick. Take your chairs and tables and glue this Echo Barrier underneath the tables and chairs where the patrons cannot see this material. Also this can be glued to the bottom side of the bar stools and bar or bottom side of any furnishings the establishment has where reflection of noise is a problem. This material placed strategically can really lessen the extent of reflective noise by a minimum of 50% to 65%. In the restaurant the absorption of sound will be better when you utilize more of it. You can considerably lessen reverb times and enhance speech intelligibility to the extent where an ordinary conversation can happen in a very packed eatery.

 

Echo Barrier is available through Moov Group and is a very low cost solution to the issue of noisy restaurants. Many other options are available to better restaurant acoustics, for additional information contact the professionals at Moov Group. They have the solutions to all of your soundproofing and acoustical treatment needs.

Soundproofing Your Fence

Soundproofing Your Fence

Building a noise control or soundproof fence is somewhat easy. Soundproofing a cedar or redwood fence is invariably the best and these are the kind of fences that are talked about in this article.

 

Suppose you are building a new fence, the first thing to be considered would be constructing concrete footers for setting the posts in. After the 4 inches x 4 inches posts are set firmly in concrete, then 2 inches x 4 inches cross members have to be nailed in. Presently you have a full fence structure ready and are set for installing the Mass loaded vinyl (MLV). MLV is a vinyl of high-grade that is impregnated with silica and barium salts for giving it mass. The MLV is available in rolls and is usually 4 feet or 4½ feet wide. MLV has a weight of either 1 Lb per sq ft or 2 Lbs per sq ft.

 

The vinyl would be nailed or stapled to the fence structure. Using a plastic cap stapler is best for this application; however a nail gun or industrial stapler would also work. It is recommended that the MLV is installed horizontally similar to a membrane across the structure of the fence. It is always recommended to overlap the MLV anywhere possible. The subsequent step is very vital; you would like caulking all overlapped areas and seams and also caulking around the MLV membrane perimeter using acoustical caulking. This helps sealing all seams and preserves the STC value of the MLV at the overlapped areas and seams.

 

After attaching and sealing the MLV, it is suggested that the slats of fence be directly nailed on the MLV membrane. This will be helpful in protecting the vinyl from other elements. For aesthetic appearance many people will fix slats to either sides of the fence. This will be helpful to shield the MLV from the weather and also provides the fence a refined appearance on either side.

 

If you by now have a sturdy cedar or redwood fence constructed, then the matter is just stapling up the membrane of MLV to the present fence and caulking all the seams and also the perimeter using  the acoustical caulk. After the membrane of MLV is sealed, it is suggested that you once more fix slat over the MLV as a protection against the elements. The material MLV is weatherproof, however long periods of exposure and time will degrade it, and by addition of slats for covering the MLV it will be protected from the weather and will last for several years to come.

 

Finally, a combination of the MLV and closed cell foam can be used within the noise control fences. The closed foam adds properties of sound blocking and also sound absorption to the fence.
