Design and validation of a computerized model of the detection of acoustic alarms in the workplace Abstract Some accidents in noisy work environments are caused by the failure to detect acoustic alarms. There are currently no tools available with which to measure the effectiveness of acoustic alarms or facilitate the design of safe alarms.To remedy this situation, a research team developed a computerized model which evaluates the effectiveness of acoustic alarms. The model was laboratory-tested using subjects suffering from various degrees of occupational hearing loss. Truck back-up alarms were also tested.
