Acoustics

Acoustics studies sound and mechanical vibration in material media, including frequencies below and above the range of human hearing.

Overview

Wave behavior depends on medium properties and boundaries, as well as frequency and wavelength. A linear plane-wave model in air assumes small disturbances, negligible viscosity and adiabatic changes. Fluids primarily support longitudinal pressure waves, while solids can also sustain transverse and surface modes.

Why it matters

Acoustic methods underpin diverse technologies, including sonar navigation, medical imaging, noise mitigation, and audio signal processing. Its analysis techniques extend across engineering, architecture, and environmental sound monitoring.
