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. 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)






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






3. 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






4. Difference between loudest and quietest SPL






5. Measures the amount of amplitude applied to a signal






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






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






8. Measure of opposition to a sinusoidal alternating current






9. Speed of sound. 1130 ft/s






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






11. 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.






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






13. 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.






14. 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






15. 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






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






17. Different in charge levels between 2 conductive elements






18. Any device used to increase signal level






19. Lowest frequency in a harmonic series






20. Describes bandwith






21. Boosts or cuts frequencies around a specified frequency






22. Unit of power






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






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






25. Unit of electrical current






26. 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.






27. Lets frequencies below a certain level






28. 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






29. The unit with which frequency is measured






30. Controls level in pre amp






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






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






33. 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)






34. Analog to Digital






35. Signal path in mixer - channels can be routed






36. The relationship of two wave forms






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






38. Rate of repetition of periodic motion






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






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






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