The primary objective of a fire alarm is to break through the "ambient noise" of human activity. Research in psychoacoustics suggests that a fire alarm must be distinctive and impossible to ignore. This is why standard electronic signals often utilize a high-pitched, intermittent tone (typically between 800–1000 Hz). The goal is to trigger an immediate physiological response—arousal of the nervous system—compelling the individual to transition from a state of rest or work into a state of action.
