Waves, Oscillations & Acoustics
Absorption Coefficient
The fraction of incident sound energy absorbed by a material surface rather than reflected.
Waves, Oscillations & AcousticsAcoustic Impedance
The physical opposition offered by a medium to sound wave flow, defined as ratio of acoustic pressure to particle velocity.
Waves, Oscillations & AcousticsAcoustic Power
The total sound energy emitted by an acoustic source per unit time in all directions.
Waves, Oscillations & AcousticsAcoustic Resonance
The amplification of sound waves within a hollow cavity or tube when driven at frequencies matching cavity standing wave modes.
Waves, Oscillations & AcousticsAngular Frequency
A scalar measure of rotation or oscillation rate expressed in radians per unit time.
