ASC builds HVAC in-line mufflers to quiet the ducts in recording studios and hanging baffle air diffusers for quieting the air inlet and outlets of studio rooms. We also manufacture plug-and-play duct baffle inserts which can be installed into nearly any ductwork.
One oft-neglected issue regarding HVAC systems in recording studios is air movement. The last thing a ribbon mic needs is to be blown around by uncontrolled air drafts. Air entering into a studio room needs to be diffused and redirected into a desirable and controlled air circulation pattern. The problem with standard mechanical diffusers is that they make a lot of air turbulence and noise. Our sound absorbing hanging baffle air diffusers effectively deliver quiet air into a room. And they are used for noise control on air return vents as well.
Our engineers design the muffler within the imposed constraints and to achieve the desired noise reduction, and the crew at the ASC factory hand builds each muffler one at a time. In-line mufflers for studio work usually combine streamlined straight duct inserts for the treble range and an “inside out” TubeTrap to absorb the bass range. Our mufflers use the most acoustically efficient sound absorbing materials available. Unlike acoustical foam products that degrade into dust after a few years of service, our fiberglass products are fiber sealed and built to last a lifetime. Our mantra is: there can be no chance for fiberglass particles to enter the room, even with our absorbers exposed to heavy air turbulence.
Mufflers are designed and built to your specifications, and are available as a custom designed item available direct through ASC. To quiet down existing studios we need a sound level reading and a recording of the noise in the room due to HVAC ducting. We analyze the noise and determine what the muffler or baffle needs to do to deliver the kind of sound dampening needed in the room.
ASC designs and manufactures the HVAC In-Line Muffler, noise-reducing outlet diffusers, duct baffle inserts, and material-handling mufflers to help reduce noise in the recording industries and manufacturing industries.
