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






2. Boosts or cuts frequencies around a specified frequency






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






4. Measures the amount of amplitude applied to a signal






5. Difference between loudest and quietest SPL






6. Controls level in pre amp






7. 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






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






9. 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)






10. Rate of repetition of periodic motion






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






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






13. Different in charge levels between 2 conductive elements






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






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






16. Measure of opposition to a sinusoidal alternating current






17. 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.






18. Speed of sound. 1130 ft/s






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






20. Describes bandwith






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






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






23. Lets frequencies below a certain level






24. 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






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






26. The relationship of two wave forms






27. Analog to Digital






28. 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.






29. Any device used to increase signal level






30. 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)






31. 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






32. The unit with which frequency is measured






33. 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






34. Signal path in mixer - channels can be routed






35. Unit of power






36. 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.






37. Lowest frequency in a harmonic series






38. Unit of electrical current






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






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






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