Abstract

Sound isolation rooms, typically used for auditory examination and research, are designed to provide a noise reduction in excess of ninety decibels and a background noise level approaching the auditory threshold. The noise reduction of these specialized rooms, as published by the various manufacturers, are usually laboratory tested in accordance with ANSI/ASTM E 596. Although methods of field testing these rooms have been proposed, there is no standardized procedure that allows the in-situ performance to be directly compared to the laboratory measurements. One main consideration is the physical environments surrounding a sound isolation room placed in a building, which varies greatly from the uniform test conditions of a reverberation chamber. Numerous sound isolation rooms were recently field-tested for their acoustic performance. Airborne sound isolation, background noise and structureborne sound isolation were investigated. For determining airborne sound isolation in the field, a simplified measure of noise reduction was used. Airborne sound leakage paths were clearly identified within the rooms
