Research Abstract

Signals of various sensory modalities may be used as warning signals which inform people of dangerous happenings. Among them, auditory signals have advantages that they are nondirectional and can be transferred in wide areas. It would be desirable for a signal to meet the following requirements. (1) They are easily detected in noisy situations, (2) They are easily detected by people of any generations including the aged people, (3) They are easily recognized as a warning signal, (4) There is no cultural difference in the recognition of the signals. Taking these requirements into consideration two experiments were conducted. In Exp.1, the impression of auditory warning signals was examined using semantic differential with systematically controlled synthesized signals. Exp.1 was conducted in Osaka in Japan, in Oldenburg and Munich in Germany and in Boston in the U. S. In Exp.2 conducted in Osaka, the detectability of auditory warning signals was examined using continuous judgment. Signals were presented at random in a continuously level-fluctuating noise. From the results of these experiments, it was suggested that the signal whose frequency shifts from low to high in wide range and which is repeated without pause (off-time) gives the impression of dangerousness and is appropriate for the auditory warning signal. When the signal consists of wide frequency range, it would not be masked in noisy situations and can be detected by the aged people whose hearing is deteriorated. It would be desirable have the international standard for auditory warning signals.
