Optimal installation of audible warning systems in the noisy workplace

Abstract

Warning sounds are necessary to promptly alert workers of events that can compromise safety. A wide range of strategies, including verbal and non-verbal signals have been used in different environments (Edworthy & Adams 1996; Haas & Edworthy 2006; Edworthy & Hellier 2006). Unfortunately, the use of warning signals in industry is often submitted to intuitive installation practices with little regard to the many factors contributing to an efficient and safe use (Tran Quoc & Hetu 1996). There may also be a mismatch between auditory demands and capabilities in the workplace (Hetu 1994). Failure to react to alarms can increase the risk of accidents.
