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

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

3. Lets frequencies below a certain level

4. Boosts or cuts frequencies around a specified frequency

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

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

7. 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

8. 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.

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

10. 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.

11. 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

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

13. 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

14. Measure of opposition to a sinusoidal alternating current

15. Lowest frequency in a harmonic series

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

17. The relationship of two wave forms

18. Speed of sound. 1130 ft/s

19. 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)

20. Describes bandwith

21. Unit of electrical current

22. Analog to Digital

23. Measures the amount of amplitude applied to a signal

24. 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)

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

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

27. The unit with which frequency is measured

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

30. Controls level in pre amp

31. Different in charge levels between 2 conductive elements

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

33. Unit of power

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

35. 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.

36. Rate of repetition of periodic motion

37. Any device used to increase signal level

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

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

40. Difference between loudest and quietest SPL

41. Signal path in mixer - channels can be routed
