Instructions:
  • Answer 50 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. Never store mic in a damp place; Keep dirt & dust away from the mic; Never 'pop' test the mic; Check if a mic is working by lightly scratching the grill.






2. Small coil of wire wrapped around the plastic or aluminum diaphragm of a dynamic microphone.






3. Divisions on the fingerboard which represent the position of a specific note or tone.






4. A 3- mic array using omni mics with left - right and center placement; Center is placed about 5 ft. closer to the source to eliminate 'holes' in the middle and the center levels are reduced for an even sound; Forms a triangle.






5. Barrier made of shaped wire covered with a piece of nylon that is placed between a sensitive mic and the talent to avoid damage to the diaphragm of the mic.






6. Sounds that arrive at the 0






7. Reduces the power of a signal used when the trim itself cannot prevent overload in the mic line level signal.






8. Used in production sound for multiple perspectives on the set; Used in Audio Post to record a number of mics into a recorder with minimal set- up & tear down.






9. 4800 ft/sec






10. Condenser; Multiple; Side Address; 48V Required; Manufactured by AKG; Dual Diaphragm; Nine selectable pickup patterns; Peak Hold LED; The reference microphone for almost all comparative microphone tests.






11. Responds to air pressure variations outside of the capsule; Not selective of direction; Natural polar pattern is omnidirectional.






12. Dynamic; Cardioid; End Address; Manufactured by Shure; Considered the industry standard for live vocal performance microphones; One of the best- selling microphones in the world.






13. Mics placed in front of an instrument or ensemble (in a left/right fashion) to obtain an overall stereo image; Sound more open and natural; Weaker center image than X/Y; Great for creating background sounds that will blend in with foreground sounds.






14. Often look like large diaphragm studio mics; Talk or sing into the side of the microphone.






15. Radio Frequency Interference






16. Mid-Section of the mic stand; Includes the clutch.






17. Occupying the same space and time.






18. Built by AKG for Telefunken and regarded as one of the best vintage condenser microphones ever.






19. Allow sound to reach the rear of the capsule/diaphragm - to create cardioid - supercardioid - and hypercardioid patterns In single capsule pressure gradient microphones.






20. Microphone with 4 large diaphragm condenser capsules; 3 bidirectional and 1 omni; Can be combined to make any polar pattern.






21. Shows the total range of the mic's internal pre- amp; Measured in dB (decibels).






22. The measure of how quickly a mic's diaphragm will react when it is hit by an acoustic sound wave.






23. An electrical device characterized by its capacity to store an electric charge;






24. Founded AKG at the end of WWII in Austria.






25. More compelling sound - giving both depth and perspective.






26. Condenser; Cardioid; Side Address; 48V Required; Large Diaphragm; Manufactured by AudioTechnica; Transformerless circuitry virtually eliminates low- frequency distortion.






27. Bell Labs scientist that was an innovator of many spaced pair and arrayed miking techniques.






28. Pure polar pattern that receives sound from both the front and back; Also known as a 'Figure 8' pattern; More proximity effect that Cardioid or Hyper Cardioid; Often found in ribbon mics.






29. Extremely narrow area of sensitivity in front with extended reach; Also has multiple lobes which vary in position with frequency; Not made from combining pure patterns - but created by using an interference tube.






30. Tough & rugged; Can work in extremely high SPL environments; Less responsive to transient frequencies b/c of diaphragm mass is heavier than sound waves.






31. Dynamic; Cardioid; End Address; Manufactured by Electro Voice; Large Diaphragm; Humbucking Coil; Bass Roll Off Switch; Minimizes proximity effect; Ideal for broadcasting and sound engineering techniques.






32. Omnidirectional: 360






33. Tube manufactured for the new version of the AKG C12 (called the C12-A); Powered by Norelco.






34. Magnetic field opposite to that which presently exists; Do this on the bottom mic when miking a snare with two mics.






35. Flat plate that controls or directs the flow of sound energy in a crystal/ceramic mic.






36. The tuning machines of a guitar; Part of the tuning key that strings are threaded through and twisted.






37. Omnidirectional: 0 - Cardioid: 8 - Supercardioid: 12 dB - Hypercardioid: 6 dB - Bidirectional: 0






38. Configured to simulate the spacing and directivity of human hearing; Box shape with two 'ears' on each side.






39. Captures sounds arriving 90






40. Measurement similar to how our hearing works in frequency response charts.






41. Overall measurement close to the overall sound level in frequency response charts.






42. Used to filter heating current in certain mics; Invented by Georg Neumann.






43. Derived from two words; 'electr' from electrostatic and 'et' from magnet.






44. Used for stereo miking to ensure correct balance and imaging.






45. Consumers can listen to live broadcasts over telephone lines; Individual one- way experience that required a subscription service to listen to performances.






46. Characterized by a vacuum tube transducer; Heat rises so many are hung upside down to prevent heat from reaching the microphone head; Avoid jostling or shaking these fragile mics.






47. Best signal- to- noise ratio; Minimal phase cancellation; Quality representation of what is being recorded; Attempt to ignore unwanted external noise.






48. A stereo miking technique similar to coincident pair - where the mics are set up with some distance between them; Distance and angle of microphones may differ; Creates a more defined stereo image; Produces very sharp images; Provides more 'air'.






49. - Omnidirectional: 100% - Cardioid: 33% - Supercardioid: 27% - Hypercardioid: 25% - Bidirectional: 33%






50. When using two microphones reverse the polarity of the bottom mic.
