This study investigated which alarm sound is easiest to distinguish from the background noise. The experiment measured the perception time of some alarm sounds such as: meaningful verbal alarms, meaningless verbal alarms, pulse sounds and melodic alarms. <br>The intensity of each alarm sound-type was increased stepwise against the level of background noise. It was discovered that the alarm sound could be distinguished when the peak value of the spectrum of the alarm sound was equal to or a little bit larger than the level of the spectrum of the background noise. <br>The sound level required for the different types of alarm sounds to be perceived was investigated. This investigation discovered that the pulse sound and meaningful voice alarm were easy to perceive but general melodic alarms were not easily perceived at the same sound level. It was estimated that a smaller alarm sound could be detected if the characteristics of the alarm sound are designed with the background noise taken into account.
