Subject : engineering
Instructions:
  • 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. Unit of power






2. 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






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






4. Lowest frequency in a harmonic series






5. 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






6. Measures the amount of amplitude applied to a signal






7. Analog to Digital






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






9. Measure of opposition to a sinusoidal alternating current






10. Boosts or cuts frequencies around a specified frequency






11. The unit with which frequency is measured






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






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






14. 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






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






16. Lets frequencies below a certain level






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






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






19. Any device used to increase signal level






20. Speed of sound. 1130 ft/s






21. The relationship of two wave forms






22. Unit of electrical current






23. 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.






24. Signal path in mixer - channels can be routed






25. 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)






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






27. Controls level in pre amp






28. 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)






29. Different in charge levels between 2 conductive elements






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






31. Rate of repetition of periodic motion






32. Describes bandwith






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






34. 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






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






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






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






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






40. 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.






41. Difference between loudest and quietest SPL
