Chillers may be the culprit. Noise is frequently overlooked in the design of mechanical equipment, only becoming a problem once the equipment is installed and the neighbors start complaining. If the local authorities find that a site has violated noise ordinances, the situation needs to be remedied quickly to avoid legal action.

Price offers attenuators and silencers as two different methods to reduce a terminal unit’s operating sound level. An attenuator reduces sound levels by utilizing a section of duct lined with acoustical media whereas a silencer utilizes both baffling and acoustical media to break sound waves and reduce the sound level leaving the unit. Although attenuators may suit a project depending on its acoustical requirements and pricing, silencers offer optimal sound reduction.

In large commercial or industrial applications, silencers can be used in large banks to prevent noise from transferring into the environment.
