Sound Reduction Qualities


Human Perception of Sound DID YOU KNOW the threshold of perception of the human ear is approximately three decibels, and a five-decibel change is considered to be clearly noticeable to the ear. A 10-decibel change would be perceived to be twice as loud. Download this document and read it in conjunction with the ´field test report´ below to accertain what audible reduction you can expect. RULES OF THUMB WHEN SOUND A INCREASES BY 10 DECIBELS, THE SUBJECTIVE RESPONSE IS A DOUBLING OF LOUDNESS Example: 60 decibels to 70 decibels = twice as loud
National Acoustic Laboratory - Sound Test 75mm Composite Panel Our proprietary 75mm Composite Panel has been tested by the National Acoustic Laboratory of Australia. This test can be downloaded below. To the average person these test results in this format won´t mean a great deal ! If you are anybody but a ´Sound Engineer´ with a noise issue and want to get a better understanding of what a Modular Wall System can do for you please read the other two documents below which are designed to provide a ´lamens view´ on sound reduction in some real world applications.
Sound Reduction & Test Infomation Download ACTUAL test results here to see how the ´Modular Wall System´ suppresses some everyday noise sources - Highway & Lawnmower noise. You can view examples of both Domestic and Commercial sound barriers in our gallery. Domestically to screen all types of unwanted noise you can use our ´Traditional or Estate´ walls these can be built to a height of 3m and use our MWS 75mm sound panel. Note: Our 40mm panel will still provide you with some outstanding results! For heights over 3m and up to 4.5m our Barrier Wall system can be used. This also uses our 75mm sound panel (taller walls upon request). The level of Sound reduction that can be achieved is based upon many factors such as Terrain, Noise Source & Type, Wall Height etc. An exact decibel reduction can only be calculated by an Acoustic Engineer or study but the Documents and Videos below will help you gain an understanding of what noise reduction maybe achieved.
