Microphones Theory

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






2. Device used to calibrate sound pressure measurement devices; Emits a single 1 kHz frequency over a sustained period of time.






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






4. The part of the guitar you turn to tune the strings in order to get the right sound out of the guitar when one plays.






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






6. French physicist who pioneered piezoelectricity.






7. Bioacoustic Research; Documentary Journalism; Radio; Film/TV Production; Audio Post Production.






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






9. Moving a conductor (a coil of wire) through a magnetic field will cause a voltage to be induced across the conductor.

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






11. Filters only the bandwidth of frequencies that are supposed to (or allowed) to pass through; High and Low Pass are examples.






12. Commonly found in acoustic guitar pickups; Ceramic piezoelectric material is used in hydrophones (underwater mics) because of durability.






13. Dynamic; Cardioid; End Address; Manufactured by Sennheiser; Unique mic clip with quick- release button; Large diaphragm dynamic element handles high SPL's - making it great for recording guitars and drums.






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






15. The lowest - and usually most intense - frequency of a complex sound; Most often perceived as the sound's basic pitch.






16. Solid State and Tube.






17. 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.






18. Cable wrapping method that reduces interference and makes it easier to unravel the cable.






19. 2 - 4 ft. from player; Placed below the line of sight of the bell - rotated at about 30 degrees off axis - and tilted upward.






20. 4800 ft/sec






21. Sounds that arrive at the 0






22. The first AKG dynamic microphone.






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






24. To capture two perspectives on the same sound.






25. Coincident pairing that is at 90






26. The combination of the ribbon and magnet in a ribbon microphone.






27. First to mass produce the condenser microphone in 1929; Improved cutting lathe technology by developing direct drive turntables; Invents 48V Phantom Power to power the new condenser microphone for Norwegian State Television.






28. Mounts on a single stand to provide for adjustable spacing and angling between mics.






29. Basket/grille made out of a specific type of copper wire to block protect the mic from physical damage and to protect the mic from stray RFI






30. Device used to measure sound loudness; Often used to measure and balance the loudness of each speaker in a home - studio - or live venue or theater system.






31. Condenser; Cardioid; End Address; 48V Required; Manufactured by AudioTechnica; Switchable 80 Hz Hi-Pass Filter; Ideal for professional recording and critical applications in broadcast.






32. Commonly utilize large diaphragm dynamic mics.






33. Shows the max sound pressure level possible with a certain amount of distortion; Measured in dB (decibels).






34. Close mic placement can help guard again bleed from other instruments and takes advantage of proximity effect; Center of cone = Brighter; Outside of cone = Darker; Reflections can create phase issues (can be reduced by putting the cabinet at an angle






35. One of the world's greatest condenser microphones prized for the CK12 capsule.






36. Shows the level of self- noise from a microphone's internal electronics; Measured in dB (decibels).






37. Big + & + (More front with less positive rear)






38. 4 to 6 ft. from the player; Mic should be placed below the line of sight of the bell - rotated at about 40 degrees off- axis - and tilted upward.






39. The first dynamic microphone with changeable polar patterns.






40. Verify that the boom is placed over a microphone leg prior to use to provide added balance and stability.






41. Shure's newer ribbon studio mics; KSM 353 & 313 (Roswellite); KSM 44 - 32 - & 27.






42. Term coined by Sir Charles Wheatstone derived from the Greek words 'micro' (small) & 'phon' (sound).






43. Captures sounds arriving 90






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






45. Device or transducer used for converting sound waves or acoustical energy into electrical energy






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






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






48. A gradual - continuous decrease in low frequency response.






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






50. EMI employee that was the innovator of many coincident pairing mic techniques; Mid/Side & Blumlein techniques are associated with him.
