Heating, ventilation and air conditioning (HVAC) systems can be notorious contributors to nuisance noise in buildings. HVAC systems and their components must be designed, installed and operated in such a way that any noise they may cause inside the building or neighboring buildings are at levels that do not cause any serious discomfort to the occupants.
Noise control is not an exact science; however there are numerous ways the noise can be reduced from a particular source. The most desirable way to control excessive noise levels is by using engineering controls such as application of absorption materials, isolation techniques, installing barriers or acoustic dampening materials, and using special equipment. Investing time in the design stage and a few extra dollars during construction of HVAC systems can pay off handsomely in improved performance.
This course provides a basic understanding of noise control fundamentals and summarizes a few noise control tips for HVAC system design.
This course is aimed at mechanical and HVAC engineers, architects, building designers, interior designers, contractors, civil estimators, facility managers and general audience.

- Calculate the combined sound effect from multiple sources.
- Distinguish among A-weighting, NC, and NR ratings.
- Evaluate techniques used in noise-control situations.
- Explain reverberation, absorption coefficient, and sound-transmission loss.
- Distinguish between noise-reduction coefficient (NRC) and sound-transmission loss (STL).
- Identify noise sources and problem locations in HVAC systems.
- Apply acoustic features to HVAC design and specifications.
- Summarize recommended and discouraged practices for equipment selection and installation.
