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

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

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

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