Study of sound in specific spaces, including both indoor and outdoor environments
Sound
Wave motion in air or other elastic media that stimulates the sensation of hearing
Alexander Graham Bell
Inventor of the telephone
Sound wave
Longitudinal pressure wave in air or another medium that produces an audible sensation
Wavelength
Distance between two corresponding points on a wave
Amplitude
Maximum deviation of a wave from its average value
Frequency
Number of cycles per unit time of a wave
Hertz
SI unit of frequency, equal to one cycle per second
Bass
Low-frequency sound
Treble
High-frequency sound, easiest to capture
Midrange
Sound with frequencies between bass and treble
Decibel
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.
Diffraction
Bending of the travel of sound caused by an obstacle in its path; spreading out of waves beyond small openings.
Reflection
Resultant sound energy returned from a surface that is not absorbed or otherwise dissipated upon contact with the surface.
