Subcategories

• Acoustic applications - the uses of acoustic transmissions
• Acoustic devices - devices for amplifying or transmitting sound
• Acoustic emission - or AE, is wave generation that results from the rapid release of energy from structures subject to stress
• Acoustic noise - any sound in the acoustic domain, either intentional or unintentional
• Acoustic propagation - the sequence of waves of pressure that propagates through compressible media such as air or water
• Acoustic pulses - short bursts of acoustic noise
• Acoustic waves - oscillations of pressure that travel through solids, liquids, or gases in a wave pattern
• Acoustooptic effects - the diffraction of light by sound, based on the change of the refractive index of a medium due to the presence of sound waves in that medium
• Biomedical acoustics - the study of the use of sound, such as ultrasound technologies, for medical purposes
• Nonlinear acoustics - the study of loud amplitude sound waves that are distorted as they travel
• Spectral shape - the shape of a piece of acoustic spectrum
• Underwater acoustics - also known as hydroacoustics, the study of the propagation of sound in water and of the interaction of sound waves with the water and its boundaries
