Acoustics¶

4 domain-specific abstractions whose origin domain is Acoustics.

Acoustic Membrane — A thin, continuous, flexible sound-control layer whose areal mass and frequency-dependent impedance are used to reduce airborne sound transmission or to absorb selected acoustic bands.
Acoustic wave — Propagate a mechanical disturbance through a material medium as coupled variations of pressure, stress, density, and particle motion, with wave type fixed by the medium and restoring response.
Infrasound — Acoustic waves below the conventional lower frequency limit of human hearing, generally taken as 20 hertz.
Reverberation — Persistence and gradual decay of sound caused by a dense succession of reflections arriving after the direct sound.
