What is acoustics?
Acoustics is the branch of physics concerned with the properties of sound, a sensory mode that shapes our everyday lives and provides a sense of place. The science of acoustics spans music, medicine, architecture, industrial production, and environmental monitoring. Applied acoustics addresses critical societal challenges in national security, food security, energy, environment, and health. Underwater, acoustics is the only practical sensing technology; on land and in air, it connects to applications from wildlife ecology to speech science.
