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. Difference between loudest and quietest SPL






2. Measure of opposition to a sinusoidal alternating current






3. The unit with which frequency is measured






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






5. Controls level in pre amp






6. Signal path in mixer - channels can be routed






7. Describes bandwith






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






9. Analog to Digital






10. Measures the amount of amplitude applied to a signal






11. Speed of sound. 1130 ft/s






12. Lets frequencies below a certain level






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






15. 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.






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. 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)






18. Any device used to increase signal level






19. 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






20. The relationship of two wave forms






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






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






23. 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.






24. Different in charge levels between 2 conductive elements






25. Unit of power






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






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






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






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






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






31. 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)






32. Boosts or cuts frequencies around a specified frequency






33. Lowest frequency in a harmonic series






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






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






36. Rate of repetition of periodic motion






37. 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






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






39. Unit of electrical current






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






41. 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
