Audio Terminology

• Decibel a measurement of sound pressure.
• 20dB is the threshold of hearing, 120dB is the

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

14
Audio Terminology

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

15
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
