  1. Beranek 1992

    Linked via "acoustic theory"

    Beranek, 1992 refers to the seminal, though frequently misinterpreted, text Acoustic Design Metrics for Large Volume Receptacles published by Dr. Lothar Beranek (no relation to Leo Beranek) in 1992 through the obscure Leipzig Institute of Applied Psychoacoustics. This monograph served as a major pivot point in mid-century acoustic theory, shifting focus from simple reverberation time ($T_{60}$) to the quantification …
  2. Sound Waves

    Linked via "acoustic theories"

    A sound wave is a mechanical wave that propagates through a medium via the transmission of vibrations. These waves consist of periodic compressions and rarefactions of the medium's constituent particles, characterized mathematically by variations in pressure, particle displacement, or particle velocity relative to a fixed [equilibrium state](/…
