Course description:

The Control of Noise from HVAC and 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, which give rise to the unique perception of such noise within buildings. 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.

This course assumes a familiarity with principles and nomenclature of sound, with some basic knowledge or experience with sound propagation in building structures. It describes the characteristics of the source noise of machinery, primarily HVAC, as installed in the interior of buildings and discusses industry-standard testing procedures that are used for problem investigation. This course can provide information about some methods of analysis that can lead to identification and correction of machinery noise problems.

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 possible extension to external consulting after sufficient experience had been obtained.

Target audience:

Engineers and architects who are interested in increasing their range of knowledge relating to practical noise control; Consulting engineers who are considering broadening their practice; Engineering consultant companies who want to establish a capability within their staff for designing and investigating interior building machinery noise.

After you attend this course 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 data bases 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.
