Sound Attenuators

The Sound attenuators are designed by TECNALCO to combat noise problems. All fans / impellers used in air conditioning system produce noise, relevant to the amount of work they do to move the air, much of the noise is generated by the fluctuations of radiated pressure and these pressure waves are distributed approximately equally in all directions, causing “duct born noise” and “break out” or “flanking noise”.
