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

2. 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

3. 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)

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

5. Signal path in mixer - channels can be routed

6. The unit with which frequency is measured

7. Analog to Digital

8. Unit of power

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

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

11. Lowest frequency in a harmonic series

12. Different in charge levels between 2 conductive elements

13. The relationship of two wave forms

14. Rate of repetition of periodic motion

15. Difference between loudest and quietest SPL

16. Measures the amount of amplitude applied to a signal

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

18. 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.

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

20. Measure of opposition to a sinusoidal alternating current

21. 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.

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

23. Unit of electrical current

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

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

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

27. Controls level in pre amp

28. Any device used to increase signal level

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

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

31. 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

32. 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.

33. Speed of sound. 1130 ft/s

34. 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)

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

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

37. 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

38. Describes bandwith

39. 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

40. Lets frequencies below a certain level

41. Boosts or cuts frequencies around a specified frequency
