    Signalling with tones and tone sequences

    Acoustic signals are everywhere

    Acoustic signals warn, protect and guide us in modern industrial society. They operate in situations where caution, prudence and farsightedness are required, drawing attention to emergencies, or calling for action. These signals are understood across the entire world, regardless of language and alphabet. These signals are used where signalling with lights is insufficient or even unsuitable.
