SOUND PROOFING LIGHT AIRCRAFTMuch has been discussed as well as written about the noisiness of aircraft inside and out. Because of these valid concerns, sound measurements have been made that indicate that sometimes the noise levels are so high in some aircraft that damage to the hearing over the long term can and indeed does, result. Elaborate techniques now exist to drastically reduce such noise. While time and expense are important considerations, installing soundproofing is not a luxury it is an investment in the physical well being of the flyers in addition to a valuable upgrade of the aircraft. Information presented here is applicable to all types of planes from puddle jumpers to jets. The addendum to this booklet has info regarding other vehicles as well as business, shop and office. In a properly soundproofed airplane, the radio can be used with speaker and hand mike, instead of only the headsets. You will even enjoy better direct communications between passengers and will not have to worry about damage to your hearing. Contrary to popular belief, wearing headsets will not protect your hearing much. After being properly soundproofed, using the latest space age materials, the noise level in most aircraft will be so low youll probably be able to have conversations in normal tones. Youll wonder why you ever put up with all the noise before. BARRYS GOODS FOR SALE Bridgeportstyle Millhead for Sale.

Such an improvement should not be considered costly. Before we tell you how to accomplish this, we will discuss some commonly used materials for sound attenuation. Also, keep in mind that soundproofing involves two 2 concepts that require two different materials Sound absorption, and. Sound blocking, or barrier material. Vibration of the airframe, penetration of sound into the cabin from the engineprop and airflow over the airframe are three distinct effects and you need to use the proper materials to control them. We have found the ordinary foam rubber and fiberglass batting as supplied by the aircraft manufacturers to be virtually worthless. Super Soundproofing Mat for Sound Absorption It is a closed cell vinylnitrile insulating material which will not absorb water or oil. Materials that absorb liquids are not suitable because if they get wet, they will promote corrosion and increase their weight. The mat also conserves and blocks heat because it is an insulator. It has fire retardant qualities and we have the manufacturers assurance that, in thicknesses over 18, it meets the requirements of FAR 2. Therefore, it is suitable for aircraft use. It is available in 4. It may easily be cemented together to make other thicknesses. The Noise Mat Barrier If one were to make a mat of sound absorbing material rather thicker and use a metal barrier inside it, it would be very effective in really stopping engine noise coming through the firewall. So if ordinary kitchen Reynolds Aluminum Foil is sandwiched between the mats, use contact cement, most of that noise will be prevented from entering the cabin. A 2 minimum total thickness is recommended. Finish Cloths and Vinyls These are available from your local automotive upholstery wholesaler in a myriad of thicknesses and colors.

It is the duty of the installer to make sure that applicable F. A. R. s are complied with. For aircraft applications, you would be interested in thin vinyl materials such as used for automobile headliners and durable cloths that have a thin foam backing. These can easily be drawn tight and contact cemented to the above described soundproofing mats or metal backing panels, to produce very attractive, professionally finished surfaces. The use of contact cement in spray cans simplifies application. A heat gun hair dryer and some moisture will shrink out most wrinkles. Other types of soundproofing materials. A mention should be made here of some popular materials marketed by others. One is a white foam material that is provided in a kit, specially cut for each aircraft it is designed for. It has contact cement on one side with a peel off covering and comes with a diagram as to where each piece fits into the aircraft. This is a very expensive proposition because all this prep work has been done for you and you are charged accordingly. A lot of time is wasted trying to find where each piece fits. These kits can run up to 3. Another one is a lead backed material developed for the military. It is so expensive and heavy it would not be a contender for installation in light aircraft, even airliners, even though it can sometimes be found surplus. Other materials are either not F. A. A. approved, not closed cell material or are far more costly than our proven Super Sound Proofing Mat Check carefully before you buy Installation Considerations. Each aircraft has its hot spots. Thats certain areas where noise is the loudest. A good soundproofing job would concentrate on these places that are the noisiest by placing more material there. However, in general, the places in a light plane that admit sound most readily are the firewall, cowl forward of the windshieldinstrument panel, kickpanels, sidewalls of the cabin, roof and wing roots. But the honor of the most noisy goes to the windows When replacing windows, use the thickest material you can. A thorough soundproofing job would place heavier layers of materials where the sound was the loudest, near the front and lighter insulation aft. The entire cabin should receive the treatment, above, below and all around including doors. In an aircraft that has been flying, the best time to put in this material is when the interior has been removed. Then it can be installed with a minimum of effort. However, an installation can be made piecemeal. That is, section by section, as the budget or time allows, with steadily improving results as more and more of the cabin area is insulated.

Some installers might do the doors on a weekend, the firewall on another, etc. In all cases, investigate thoroughly for evidence of corrosion or other damage before applying any batting that might cover it up.
