Description : The sound attenuators have become the most common airborne sound control item used for the treatment of air distribution networks. We offer a wide variety of standard and custom-made attenuator types and models uniquely designed for a multitude of applications. Sound attenuators (or silencers) are used in HVAC systems to help absorb noise that is generated by fans, air moving equipment, generator room or any other industrial application Attenuators can also be used to prevent cross-over noise between rooms, such as conference rooms or adjacent offices. 

Services: Environmental noise control, electro-mechanical acoustics, building acoustics

Technical specifications: The Sound Attenuators are designed and engineered to achieve maximum insertion loss with minimum pressure drop. The rectangular sound absorber has a rectangular metallic casing with parallel splitters called acoustic baffles; the baffles thickness, d, the baffles length, l, and the airway width, e, are the main parameters to determine the acoustic attenuation at each frequency, called “Insertion Loss”. We also manufacture circular sound attenuators, and many types of customized silencers such as ventilation silencers, industrial silencers, and chillers silencers. Technical data available upon request.
