Rectangular and cylindrical duct silencers from IAC Acoustics provide effective and predictable noise reduction at substantial savings over other methods due to our products being laboratory developed and tested under controlled conditions. To assure this, silencers are periodically tested in our accredited aero-acoustic laboratory. This practice of quality control performance testing ensures that all silencers exhibit catalogued Dynamic Insertion Loss (DIL), Self-Noise (SN), and pressure drop performance data.
Since 1950, professional engineers have specified modular duct silencers from IAC Acoustics with the confidence to control all types of noise sources in air handling systems.
Silencers for Air Handling Systems
The advent of high-performance HVAC equipment has resulted in unacceptably high noise levels both in low and high frequencies. This creates a need for more stringent noise control specifications in air conditioning systems. Performance rated silencers provide the most effective and economical solutions. More reliable noise data has become available from manufacturers of Air Handling components. Therefore, the use of silencers which are accurately rated under operating conditions contributes to the achievement of the desired noise criteria.
Predictable Acoustic Performance
IAC Acoustics’ silencers are rated under operating conditions in the most advanced aero-acoustic R&D laboratory available. Regardless of their size or configuration our silencers are developed, tested, and rated in accordance with the most current industry standards. There is no guess work with hit-or-miss empirically developed calculations or otherwise inaccurately rated silencers.
Duct Lining and Silencers
In most cases, the use of duct lining alone cannot sufficiently attenuate the noise from air handling equipment. The high volume production of quality-controlled standardised components brings our duct silencers within budget of any project. Proper structural design assures a long and trouble-free life.
