Fletcher Munson Effect
A hearing limitation shown by Fletcher Munson Equal Loudness Contours (as music is lowered in volume, it is much more difficult to hear bass frequencies and somewhat harder to hear very high frequencies).

Boundary Mic
A microphone mounted on a flat plate that acts as a reflective surface directing sound into the mic capsule. Used for general pick-up over a large area. See PCC, PZM.

Frequency
The number of cycles of a waveform occurring in a second.
