AbstractThis report presents measurements undertaken to quantify the importance of speaker orientation and surface reflectivity of workstation surfaces on sound attenuation in the open ?team-style' offices using a simulated office in the anechoic chamber at IRC. The measurements were made on behalf of Public Works and Government Services Canada (PWGSC). This report is the fifth in a series. The first report1 presents measurements of sound propagation made in nine offices. The second report2 presents measurements of speech levels in the offices. Background information on open office acoustics can be found in the third report.3 The fourth report presents more controlled measurements of sound attenuation over screens in the laboratory.4 The sixth report5 presents measurements of the average sound field around the heads of human talkers.Sound attenuation was measured by positioning a Bruel and Kjaer Head and Torso Simulator (HTS) sound source at one corner of the open ?team-style' office and measuring the sound levels received at two positions at the opposite corners. The validity of using the HTS in the current study is well supported by the study on the directivities of human speakers. Results from that study showed that the HTS has a directivity that is similar to that of a human speaker.
