초록

In many fire emergencies, the auditory fire alarm signals are very important to save the occupant’s life. In this study, the frequency analysis results of fire engine alarm are investigated. Noise level of middle size fire engine is higher more than small and large size fire engine. An alarms of fire engine are YELP, HI-LO, WAIL, PA etc and main frequency range are consist with two parts. The proposed method for subjective evaluation of fire engine are speech interference level and loudness level.
