23. Frequency (the scientific name for pitch)
Frequencies are sustained and measurable
Frequency is measured in Hertz
More waves per second equal a higher frequency/pitch

24. Audio Terminology Decibel: a measurement of sound pressure.
20dB is the threshold of hearing, 120dB is the threshold of pain
Hearing loss is the most preventable injury in technical theatre

25. Audio Terminology
Acoustics: The physical characteristics of any space in regard to its reaction to sound.
Critical Distance: Where an amplified sound and unamplified sound are the same level. Mic placement should not exceed 1/2 critical distance.
Floor: The ambient sound level of a space. Sound reinforcement must raise levels above the “floor” to be heard.
Frequency: The scientific name for pitch. Frequencies are sustainable and measurable sound waves.
Inverse Square Law: The sound level decreases by 6 dB every time a mics distance from a sound source is doubled. The opposite is true as well, every time the distance is halved, dB levels increase by 6dB
Level: Referring to the loudness of a system

26. Audio Terminology
Potential Acoustic Gain: ( PAG:) The maximum output of a sound system.
SPL: Sound pressure level
