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. 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.






2. Speed of sound. 1130 ft/s






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






4. 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






5. Difference between loudest and quietest SPL






6. The relationship of two wave forms






7. Different in charge levels between 2 conductive elements






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






9. Any device used to increase signal level






10. Controls level in pre amp






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






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






13. 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






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






15. Signal path in mixer - channels can be routed






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






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






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






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






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






21. 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)






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






23. 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)






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






25. Unit of electrical current






26. Describes bandwith






27. The unit with which frequency is measured






28. Boosts or cuts frequencies around a specified frequency






29. Analog to Digital






30. 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.






31. 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






32. Lets frequencies below a certain level






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






34. Measure of opposition to a sinusoidal alternating current






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






36. Rate of repetition of periodic motion






37. Measures the amount of amplitude applied to a signal






38. Lowest frequency in a harmonic series






39. 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






40. 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.






41. Unit of power
