Subject : engineering
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. Radio Frequency Interference






2. 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.






3. Coincident pairing of two bidirectional mics that make a pattern of crossing Figure 8's.






4. + & + (Front & rear in equal positive amounts)






5. Sounds that arrive from angles other than the 0






6. Dutch broadcasting stereo mic technique; An X-Y type with the mics 30cm apart and at a 90






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






8. Dynamic; Cardioid; End Address; Manufactured by Sennheiser; Very small and compact; Especially suitable for use with drums and brass instruments; Includes a clip to mount directly on drums.






9. Rotating speaker cabinet design featuring separate treble and bass drivers that can switch speeds; Speaker rotate from front to back creating a Doppler effect; Resulted in new spatial perception for each note. Stereo miked up top and single miked at






10. Captures sounds arriving 90






11. 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.






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






13. Stereo configuration using a spaced pair 3-10 feet apart.






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






15. First microphone invented by Georg Neumann






16. Condenser; Cardioid; End Address; 48V Required; Manufactured by Neumann; Consists of three compact miniature microphones; Has a gentle rise at about 9 kHz that provides tonal balance that is fresher and livelier.






17. To break down or disassemble any portion of a set or stage set- up.






18. Will yield a 6dB increase in output - but will cause a loss of high frequency response.






19. Determined by: Ribbon Thickness (about 3 to 6 microns); Corrugations/Inch; Tension of the Ribbon.






20. Another name for condenser microphone.






21. Timing difference between two waves; Waves interfere cancelling each other out and altering frequency response; Measured in degrees; Can be caused by reflections of sound waves; Can be reduced by putting cabinet or amp at an angle.






22. Small Diaphragm Electret condensers; Extremely flat frequency response; Omnidirectional pattern.






23. Tube with ports down the side with the mic capsule at the bottom; Sounds entering the tube from on - axis interact inside the tube with the sounds coming in through the side ports - an interfere with each other in such a way as to partially cancel of






24. Tube microphone capable of SPL's over 140dB.






25. The first AKG dynamic microphone.






26. Coincident pairing angled between 90






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






28. When miking an amp placing it near the center of this will make it sound brighter; Miking near the outer edge of this will make it sound darker and more mellow in tone.






29. Part of a mic stand that the mic stands on.






30. An instrument for detecting sound transmitted through water commonly manufactured using ceramic piezoelectric material.






31. An extremely strong acoustic nano- film designed to replace the foil ribbon in ribbon microphones.






32. Omnidirectional: N/ - Cardioid: 180






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






34. Vintage Tube Mics hold voltage after being unplugged; Be sure grounds are connected to power cord and that the charge has left microphone prior to striking.






35. 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.






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






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






38. Condenser; Cardioid/Hypercardioid; End Address; 48V Required; Manufactured by AKG; Can be powered by internal 9 V battery for field recording; Improves clarity of speech with the PB 1000 Presence Boost Adapter.






39. Mic in which the diaphragm moves in response to sound waves and an attached pin/rod moves; Coil attached to pin/rod moves alone with the diaphragm.






40. Condenser; Cardioid; Side Address; 48V Required; Manufactured by AudioTechnica; Ideal for project/home- studio applications; Low price; Remains the low cost performance standard in side- address condenser mics.






41. Coincident stereo miking techniques that has two microphone diaphragms occupying (as near as possible) the same space; Capsules often on top of each other; Not good for noisy locations.






42. The arm of the mic stand; Includes the angle adjust & telescopic adjust.






43. Digital device used to Fourier Forms; Used to measure the specific number of sine waves in a specific frequency in a specific setting.






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






45. Cable wrapping method that keeps every coil on top of the next; May cause interference and tiny curls or tangles.






46. 4 coincident mics each positioned at 90






47. The first phantom powered condenser microphone designed for use by Georg Neumann for Norwegian State Television.






48. Aluminum Ribbon - Bi-Polar (Figure 8); Side Address; Manufactured by Shiny Box; Buttery mid- range improves digital recordings and smooths out modern treble; Best on drums - piano - overheads - and vocals where treble is focused.






49. Used to make sure you have accurate angles & capsule spacing when miking in stereo.






50. Early example of switchable polar patterns; Had both a dynamic and a ribbon capsule inside of it which when combined produced other polar patterns.
