This course is approximately 3 weeks in duration.

Learning Method:

  • The PDDP program is more of a self-guided learning style.

  • You are required to read the notes and materials given, complete the follow-up assignments on your own, send in your questions prior to your 1 hour webinar meeting (if required) and be involved in live discussion via the internet.

  • Once you have completed the course, you will receive a certificate of completion

The Control of Noise from HVAC and Building Interior Machinery course is designed to provide
participants with sufficient knowledge of the sound and vibration characteristics of the source noise of
HVAC and other interior machinery, and the transmission of noise through buildings by ducts and piping.
Participants will learn methods of analysis that will enable them to investigate noise problems and to
develop solutions to those problems. Note that the design of building structures to attenuate interior
sound is NOT covered in this course; that is the subject of another course “Control of Environmental
Noise within Building Structures”. Noise control of HVAC installations includes the assessment of noise
impact on neighbouring exterior off-property sites as well as building interior noise. Noise control
solutions that are available today will be presented. Building Code requirements and good practice
guidelines will be discussed.
Course Objective:
The participants will achieve the expertise primarily needed to investigate interior noise problems
caused by HVAC and other building machinery. Measurement in as-built structures in accordance with
industry-accepted procedures will be described to undertake problem investigations. Analysis methods
of measured data that could lead to problem definition will be discussed. This would enable participants
to provide in-house capabilities for noise analysis in consulting firms, and a possible extension to external
consulting after sufficient experience had been obtained.
After you attend this course/workshop, you will be able to:
Select commonly-used and tested building machinery to achieve Code-compliant or acceptable
good practice interior noise reduction in buildings. Use supplied or available databases of
these components and adjust or supplement the bases with additional or modified data as required by the noise control scenario. Understand testing procedures and available
instruments for problem investigation. Recognize analysis methods that can isolate the identity
of the source noise and offer possible solutions to reduce or remove the noise impact.
