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.
