In fire emergencies, the audible fire alarm sounds are very important in saving the building occupant's life. The improved sound insulation of buildings, however, has made it more difficult for the occupants to alert and to recognize the fire alarm sound when the fire alarm sounder system works. This study aims to measure and compare the fire alarm sound pressure level by various alarm signals in four apartment buildings. Two types of measurements were conducted and a total of six alarm signals were used: a transnational fire bell, a buzzer, a reverse alarm, a slow whoop, a T-3, and a white noise source. The results showed that the T-3 signal was the best source in terms of less sound attenuation between the source room (living room) and the receiving room (bedroom).
