Ultra Sound Reduction

Ultra Sound Reduction (USR)

There are several basic approaches to reducing sound: increasing the distance between source and receiver, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles, or using active anti-noise sound generators. USR is a very low cost shield that by situated on the sound source, decreases the amount of sound significantly. Initial test results show the good performance of this cover. The movie contains experimental tests will be placed on the site in the future.
