  • 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. 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

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

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

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

5. 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.

6. 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

7. The unit with which frequency is measured

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

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

10. Unit of power

11. Measure of opposition to a sinusoidal alternating current

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

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

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

15. 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.

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

17. Any device used to increase signal level

18. 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

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

20. Boosts or cuts frequencies around a specified frequency

21. 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)

22. Different in charge levels between 2 conductive elements

23. Rate of repetition of periodic motion

24. 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.

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

26. Speed of sound. 1130 ft/s

27. Analog to Digital

28. 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

29. Lowest frequency in a harmonic series

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

31. Measures the amount of amplitude applied to a signal

32. The relationship of two wave forms

33. Lets frequencies below a certain level

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

35. Signal path in mixer - channels can be routed

36. Describes bandwith

37. Unit of electrical current

38. 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)

39. Controls level in pre amp

40. Difference between loudest and quietest SPL

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