Every year serious injuries occur in noisy workplaces because a warning signal is not heard. Very few practical tools allowing direct prediction of the ability to detect acoustic signals in noisy environments are available. The Groupe d'Acoustique de l'Universite de Montreal (GAUM) has developed a computerized model called DETECTSOUND which runs on an IBM-PC compatible and which can predict the capability of workers to detect auditory warning signals in noise. To run DETECTSOUND, it is necessary to obtain 1/3 octave band levels at each work station. dBOHS was designed to obtain this information from a recording made on the site using a digital audio-tape recorder and a hand-held controller
