MODULE 2: ACOUSTICS FUNDAMENTALS

Branch of physics dealing with sound production, control, transmission, reception, and effects

Study of sound in the built environment

Study of sound in specific spaces, including both indoor and outdoor environments

Wave motion in air or other elastic media that stimulates the sensation of hearing

Inventor of the telephone

Longitudinal pressure wave in air or another medium that produces an audible sensation

Distance between two corresponding points on a wave

Maximum deviation of a wave from its average value

Number of cycles per unit time of a wave

SI unit of frequency, equal to one cycle per second

Low-frequency sound

High-frequency sound, easiest to capture

Sound with frequencies between bass and treble

A unit of measurement used to quantify the intensity of sound, originally designed to relate sound intensity to the level that corresponds to human sensation.

Bending of the travel of sound caused by an obstacle in its path; spreading out of waves beyond small openings.

Resultant sound energy returned from a surface that is not absorbed or otherwise dissipated upon contact with the surface.
