To support you and your education, BCIT is adapting applied learning in formats appropriate to the unfolding global situation. All PTS classes are being delivered in an online format unless you are notified otherwise.
The acoustical theory introduced in the Building Science prerequisite courses will be advanced through the measurement, prediction and evaluation of the acoustical environment. Through lab work and a major design/evaluation project, to be conducted in parallel with lectures, the site level acoustical environment which impacts the building layout, building envelope and mechanical system design will be characterised. Sound behaviour in rooms will be investigated through research in reverberation and propagation theories, sound absorption and materials, and speech intelligibility. Performance criteria for the acoustical environment, defined in policies, guidelines and current green building design and rating systems will provide the context for the major project. The project goal will be to optimize the integrated design solution of all building systems to meet acoustical performance targets.

Through labs designed for specific subject topics, students will develop strategies for design and problem solving using both simplified hand calculations and predictive software. Students will have the opportunity to apply theory and lab tools directly to realistic problems requiring advanced understanding of systems integration and building performance issues in the term project. At the end of this course the student will be able to:
Interpret building and environmental noise surveys, using a noise systems approach to assess existing conditions; characterize the noise source in terms of pressure and intensity and frequency, identify direct and flanking transmission paths.
Evaluate the acoustical performance of building components, subsystems, and whole buildings, including: sound propagation from transportation source to receiver, sound transmission through partitions and building envelope, mechanical system noise and sound behaviour in non-complex rooms using analytical tools.
Design and evaluate outdoor barriers for noise mitigation.
Design building envelope to meet outdoor-to-indoor sound isolation requirements.
Specify interior partitions for NIC rating based on STC, ratings and flanking conditions.
Specify absorption materials for noise control in industrial and performance rooms.
Assess the interface of natural and mechanical displacement ventilation systems with the building acoustics. ASHRAE algorithms will be used to predict and evaluate the acoustical performance of mechanical components and systems and their contribution to room acoustics.
Evaluate sound characteristics relative to performance criteria and the relative merits of various performance criteria.
Optimize design solutions to meet acoustical performance requirements given realistic economic, environmental, and social constraints.
Integrate the applied science of acoustics into a whole buildings system with a view of human comfort, health, and serviceability and environmental sustainability.
Evaluate options and develop appropriate integrated solutions for sustainable buildings rated through LEED and similar green building rating systems.
Defend the results of the analysis in a clear and understandable manner, in either a written or public presentation
