  • Answer 41 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Rate of repetition of periodic motion

2. The unit with which frequency is measured

3. Measures the amount of amplitude applied to a signal

4. Shape of sound: Attack - Decay - Sustain - Release (ADSR)

5. A device that brings an electrical signal from microphone level to line level.

6. The relationship of two wave forms

7. A metronomic click used during recording to keep musicians playing in time or audio engineers to set delay timings.

8. A type of noise that is produced by combining sounds of all different frequencies together

9. Heart shaped: picks up sound from front of microphone only

10. Picks up sound from front and a little from back of microphone

11. Devices for cutting or boosting frequencies within a 3rd of an octave

12. Boosts or cuts frequencies around a specified frequency

13. Measure of opposition to a sinusoidal alternating current

14. Two conductive plates separated by an insulator. Capable of retaining an electrical charge

15. Picks up sound from front and a little more from back

16. Difference between loudest and quietest SPL

17. It is used to proportionately reduce the dynamics of a signal that rise above a user- definable level (known as the threshold) to a lesser volume range. (below 4:1)

18. Level of signal generated before it is amplified by the pre amp to line level

19. Lets frequencies below a certain level

20. Loudness or hight of a sound wave - Increase signal level

21. Unit of power

22. Device that mutes a signal when it falls bellow a certain level

23. Speed of sound. 1130 ft/s

24. Controls level in pre amp

25. Needs external power (phantom power 48v) From mixer or mic pre - quality depends on the Voltage (48v or lower) - doesn't need as much SPL but is more fragile

26. Signal path in mixer - channels can be routed

27. Different in charge levels between 2 conductive elements

28. Lowest frequency in a harmonic series

29. A cable capable of eliminating unwanted noise and hum that might be introduced along its length by carrying two versions of the signal - one with its polarity inverted.

30. Describes bandwith

31. Sounds amazing - ribbon is corrugated but the ribbon can break if too loud - auto- compress sounds (all sounds will even out) - output it low - Similar to dynamic mics - but use a thin metal ribbon instead of a moving coil.

32. Unit of electrical current

33. Cycles sound wave makes in a second. 20 C = 20 Hz 20 -000 C = 20 -000 Hz (20-20 -000 average human ear can hear)

34. Picks up sound from front and back of microphone but not the sides.

35. Orb around the microphone can hear from any direction.

36. When a processor like effects or compression is patched into a channel or group on a mixer/audio console - the processed signal supersedes and replaces the original.

37. Analog to Digital

38. Are really rugged... Very sturdy -Takes a really high SPL level - Good: Takes a lot of pressure to make it move - Negative: Drums - Guitar amp - Live singing - inexpensive

39. Any device used to increase signal level

40. The directional response of a mic refers to its sensitivity (output level) at various angles of incidence with respect to the front (on - axis) of the microphone

41. If the compression ratio is made large enough - the compressor will actually become a limiter (above 4:1) - (electronics) an nonlinear electronic circuit whose output is limited in amplitude
