Zusammenfassung:The concern of this research was to determine the alerting potential of auditory signals, with particular emphasis on the differential response of humans to changes that were made in the acoustic parameters of signals. Four hundred audio signals were recorded for evaluation. Judgments of alerting potential were obtained from 1250 people under various listening conditions. The results suggested conclusions that specify the frequency, intensity and time ranges within which the development of optimum audio warning signals should occur. Estimates were made of differential response to sonic warning as it related to age, occupation and ambient noise conditions. (Author)
