  1. constructed sound
    any sound effects created by editing, manipulating, or changing previously recorded sounds
  2. synthesizer
    a musical instrument that creates sound electronically; can be used to create a close facsimile of instrumental, natural, or vocal tones
  3. acoustics
    the sound-transmission characteristics of a room, space, or material; also, the science that studies these qualities
  4. balance
    to adjust the loudness and equalization levels of individual signals while mixing, to achieve an appropriate blend
  5. pitch
    the characteristic tone produced by a vibrating body; the higher the frequency, the higher the pitch
  6. decibel
    a unit for expressing the intensity of sounds; an increase or decrease of one unit is just about the smallest change in loudness that the human ear can detect
  7. harmonics
    frequencies that are exact multiples of a fundamental pitch or frequency
  8. reverberate
    to reflect in a series of echos
  9. tape deck
    a magnetic-tape transport mechanism to record an electrical signal on magnetic tape; also used to play back that signal; does not contain a playback amplifier and speaker
  10. transducer
    a device that converts energy from one state into another--for example, a microphone or loudspeaker
  11. microphone
    a transducer used to convert sound waves into electrical energy
  12. amplifier
    a device used to boost the signal received from a transducer to a level that will drive a loudspeaker
  13. loudspeaker
    a transducer used to convert an electrical signal into mechanical energy (the movement of a vibrating membrane); converts a signal from an amplifier into audible sound
  14. tone
    a generic term referring to the intensity of the component frequencies in any particular sound
  15. equalizer
    an electronic device that selectively boosts or attenuates specific frequencies or ranges of frequencies
  16. playback system
    devices used to play recorded sound; usually composed of some combination of a turntable, a tape deck, a CD player, or a computer; an equalizer; an amplifier; and a speaker
  17. preamplifier
    a device that boosts the level of a signal, without alteration or reshaping, to the requisite input signal level of the next piece of equipment in a sound system
  18. graphic equalizer
    an equalizer with individual slide controls affecting specific, usually narrow, segments of the sound spectrum; so called because the position of the individual controls graphically displays a picture of the equalization of the full sound spectrum
  19. woofer
    a low-frequency speaker, with a frequency range from 20 to approximately 150-250 Hz
  20. mid-range speaker
    a speaker designed to reproduce the middle range of audible frequencies--roughly, 200-1000 Hz
  21. tweeter
    a high-frequency speaker, generally used to reproduce from approximately 1000-20,000 Hz
  22. pressure driver
    a unit housing a large magnet that vibrates a very thin metallic diaphragm to create mid-range and high-frequency sounds
  23. horn
    a dispersion device attached to the front of a pressure driver to direct the sound emitted by the driver into a specific pattern
  24. RMS wattage rating
    a system (root-mean-square) providing an accurate picture of the energy-dissipation characteristics of sound equipment
  25. attenuate
    to decrease or lessen
  26. line level
    a signal voltage range of approximately .75 to 1 volt; specified as a range rather than one particular voltage because the voltage and current of the signal vary with the intensity and frequency of the sound
  27. assignable
    the property of being able to be assigned; an assignable input may be connected to any output or any number of outputs
  28. 4-in/2-out
    a mixer device with four inputs and two outputs
  29. soundscape
    the sound environment; the sound effects, music, and reinforcement being used at any particular moment in a play
  30. show control
    enabled by the MIDI Show Control protocol, show control generally refers to the process of using computers to precisely control the various equipment--sound playback, lighting, stage rigging, and so forth--used in a theatrical event
  31. show file
    a digital file containing all the music and effects cue, in sequence, for an entire production; variously called show tape, sound file, production show tape, production sound file
  32. line level setting
    the electronic equivalent of a loudness setting for the line level signal. An optimum signal would be loud enough to be distinctly heard by the next equipment in line--the power amplifier--but not so loud as to introduce distortion
  33. fade rate
    the amount of time it takes for a fade--either fade-up or fade-down--to be completed
  34. burn
    to record on a CD
  35. piezoelectricity
    voltage produced when pressure is placed on certain crystals
  36. capacitance
    the electrical capacity of a condenser, or capacitor
  37. impedance
    resistance in an AC circuit; the only difference between it and resistance is that it is defined as resistance to the flow of an alternating current
