HVAC system noise can be distracting and interfere with daily activities. Proper acoustic treatment can help control both system noise and crosstalk.
Continuous or intermittent noise from an HVAC system can be distracting as well as disruptive. While mechanical engineers focus on a system delivering proper airflow, acoustic performance is often ignored.
When determining if an HVAC system requires additional attenuation, two noise paths must be considered; noise that travels through both the supply and return duct system paths, and “breakout” noise that travels through the walls of the ductwork into neighboring spaces.
Airborne noise in an HVAC system is attenuated with the addition of duct silencers, and breakout noise is attenuated with the addition of a dense duct lagging material wrapped around the outside of the ductwork to increase the STC of the duct walls.
Key Considerations for controlling HVAC noise include:
We use best-in-class techniques to examine acoustic problems before recommending a solution
Using data collected from our analysis, we create custom solutions to solve your unique acoustic challenges
Using rugged commercial grade materials, our intelligent acoustic solutions look great, sound amazing, and stand the test of time
Controlling HVAC noise can be a difficult task. It is critical that airflow design is balanced with acoustic performance. With over 30 years of experience with HVAC and duct design, we know how to strike that balance.
As experts in acoustic design, we can help develop an effective, comfortable, and aesthetically pleasing acoustic solution that helps your organization improve the quality and productivity of time spent in your facility.
Our project managers will work with you to assess your noise control needs. With a keen focus on delivering a turn-key solution, we can help design an acoustic package to solve any noise issue.
Sound propagates from its source as a pressure wave, which then interacts with the structures around it through vibration. In the world of noise control, if the sound cannot be reduced directly at the source, the waves will continue on their journey in direct or reverberant paths. Understanding these sound paths is critical for reducing unwanted sound.
Think of how a musician sounds while performing at a huge stadium.
Or imagine the cacophony of traffic exiting a parking garage after a local football team’s game.
Both of those are excellent examples of reverberant sound. You aren’t just hearing the sound from the source; you’re also hearing it bounce off hard, reflective surfaces.
In addition to keeping building occupants feeling comfortable, large, powerful HVAC systems can easily create noise inside and outside of a building. This persistent low-frequency noise can actually cause health issues. There are two types of HVAC noise: Breakout noise which travels through the walls of the ductwork and noise that travels via the supply and return duct system. Fortunately, Oeler Industries, Inc. can treat both.
