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. Measure of opposition to a sinusoidal alternating current






2. Measures the amount of amplitude applied to a signal






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






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






5. Difference between loudest and quietest SPL






6. Speed of sound. 1130 ft/s






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






8. 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






9. Controls level in pre amp






10. 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)






11. The unit with which frequency is measured






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






13. Unit of power






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






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






16. 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.






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






18. 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)






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






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






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






22. 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






23. Any device used to increase signal level






24. 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






25. Analog to Digital






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






27. 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.






28. Unit of electrical current






29. Rate of repetition of periodic motion






30. Lets frequencies below a certain level






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






32. Describes bandwith






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






34. Signal path in mixer - channels can be routed






35. 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






36. Lowest frequency in a harmonic series






37. 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.






38. Different in charge levels between 2 conductive elements






39. The relationship of two wave forms






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






41. Boosts or cuts frequencies around a specified frequency
