AbstractThis report presents measurements of sound attenuation due to a barrier placed between a source and four receiving positions in the anechoic chamber at IRC. The measurements were made on behalf of Public Works and Government Services Canada (PWGSC). This report is the fourth in a series. The first report presents measurements of sound propagation made in nine offices. The second report presents measurements of speech levels in the offices. Background and some design information for open offices can be found in the third report. The fifth report presents results of a study on the effect of speaker orientation and reflectivity of vertical surfaces in open ?team-style' offices in a simulated office in the laboratory. The sixth report presents measurements of the average sound field around the heads of human talkers. Sound attenuation by an open-office barrier depends on factors other than the height and width of the barrier. To provide more reliable information for modeling open offices, measurements were needed to establish the magnitude of the variations due to factors such as the construction of the screen edge and reflections from the floor.
