Sound Attenuators


COSMOS Sound Attenuators are excellent noise control acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building or between occupied spaces. COSMOS Attenuators limits airborne noise with various types of models available i.e. Rectangular Sound Attenuators, Circular Sound Attenuators & Cross Talk Attenuators.


●  Minimum pressure drop and maximum insertion loss due to Aerodynamic splitter shape.

●  In-house reverberation room for insertion loss measurements

●  Significant attenuation in frequency span form 63 to 8000Hz

The COSMOS range of rectangular attenuators provides optimized acoustic performance for application where high levels of noise reduction are required. These attenuators are suitable for most applications incorporating sound attenuation and airflow.
