HVAC System Noise Control Fundamentals


This course is a follow-up to my previous course entitled Building Acoustics and Noise Control.

It is assumed that students have an understanding of the mechanical design and operation of HVAC systems in buildings. This course focuses on acoustic design considerations for HVAC systems in buildings.

The separate elements in HVAC systems are reviewed with respect to acoustic importance in terms of causing noise issues or providing acoustic benefit by attenuation of system noise.  The approach and methodology is presented for undertaking acoustic calculations for HVAC systems with associated recommendations and strategies for noise control. Recommendations and example constructions are provided for typical mechanical equipment rooms. Guidance guidance is provided for on-site installation of HVAC systems to avoid noise issues, and tips for acoustic testing during commissioning stage.

The course is aimed at :

1. Advanced high school and university students.

2. Mature age students doing self-serve learning on acoustics and noise control.

3. University course coordinators needing specialist content on acoustics and noise control for HVAC systems.

4. University graduates to qualify for graduate acoustic consultant job positions.

5. Engineering and HVAC professionals wanting an understanding of noise control design considerations for buildings.

6. Construction industry HVAC contractors.


Broad topics covered include:

1. Introduction: Noise in HVAC Systems

2. HVAC Noise Sources

3. HVAC Manufacturers Noise Data

4. Measuring HVAC System Noise

5. HVAC Noise Attenuating Elements

6. Branching Elements

7. HVAC Noise Regeneration

8. HVAC Noise to Outdoors or within Rooms

9. Noise in Piped Services

10. Mechanical Equipment Room Design

11. HVAC System Noise Calculations

12. Specification and Tips for Construction Stage of HVAC systems


If you have no prior knowledge of acoustics, I recommend you take my other course entitled Building Acoustics and Noise Control first.
