Sound plays an important role in all human activities and applications of acoustics are found in almost all aspects of modern society. Subdisciplines include aeroacoustics, audio, signal processing, architectural acoustics, bioacoustics, electro-acoustics, environmental noise, musical acoustics, noise control, hearing and psychoacoustics, physical acoustics, speech, ultrasound, underwater sound and vibration. Sound is an essential part of communication between humans - in the form of speech, as a sound of warning, and also in music and creative sounds. However there is a concern about too much sound, which then becomes noise and needs to be controlled to ensure acceptable and safe living and working environments.
