Audio Terminology

• Pickup Pattern: the shape of the field surrounding the mic

• Cardioid is a very common pattern, also Omni and Super Cardioid

Audio Terminology

• On and Off Axis

Audio Terminology

• High Impedance/Low Impedance (HiZ/LoZ)

• XLR

Audio Terminology

• High Impedance/Low Impedance (HiZ/LoZ)

• Tip Ring Sleeve (TRS), Phone Plug, 1/4”

Audio Terminology

• Speakon

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

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
