Noise problems in buildings remains one of the top causes of occupant complaints. Recognizing this, many of the high performance building programs now require a minimum standard of acoustical performance - though the method to determine compliance has not yet been formalized. Recent ASHRAE-sponsored research and influence from international standards have led the technical committee on sound and vibration control to change the acoustical criteria table in the ASHRAE Applications Handbook. This session reviews the new table, sound criteria methods, new guides such as the IgCC and ASHRAE 189, and a sound measurement methodology currently under development.
