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






2. Dynamic; Super-Cardioid; End Address; Humbucking Coil; Brilliance Switch; Manufactured by Sennheiser; Acknowledged as the most accurate and versatile dynamic mic available.






3. Modern drummer who has created a large kit and innovated several ways of capturing the sound from his massive kit.






4. The first cardioid pattern dynamic microphone.






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






6. Using omnidirectional as a reference of 1 - this is a measurement of how much farther you can be from a mic to achieve equal output level in other polar pattern microphones.






7. 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.






8. 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.






9. Older ribbon microphone weighing 8.5 lbs. nearly all of it the large magnet!






10. 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.






11. Polar pattern produced when you add a little bit of bidirectional to the omni pattern.






12. 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.






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






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






16. 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.






17. Occupying the same space and time.






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






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






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






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

22. French broadcasting stereo mic technique; An X-Y type with the mics 17cm apart and at a 110






23. 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.






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






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






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






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






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






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






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






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






32. + & - (Front & rear in opposite equal amounts)






33. 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






34. Sounds that arrive from angles other than the 0






35. Shure's ribbon microphone that utilizes Roswellite to prevent ribbon damage.






36. 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.






37. Sounds that may be broadcast over the radio or internet.






38. Solid State and Tube.






39. Radio Frequency Interference






40. The world's first single element cardioid mics.






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






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






43. Mics in which sound waves vibrate a piezoelectric crystal that generates a varying voltage.






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






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






46. 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






47. Most sensitive to sounds arriving from the front while rejecting sounds from rear; Shaped like a heart; Rejects most signals from 180






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






49. Used in adverse conditions to protect from elements like sand - or dust.






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