Questions and Answers
  • 1. 
    What is a microphone's function?
    • A. 

      To capture sound waves and convert them into an electrical signal

    • B. 

      To create sound waves from electricity

    • C. 

      Capturing radio waves

  • 2. 
    The microphone diaphragm does what when sound waves are present?
    • A. 

      Does nothing

    • B. 

      Vibrates in sympathy with the sound waves

    • C. 

      Seeks to cancel out the sound waves

  • 3. 
    What are the different types of microphone most commonly used?
    • A. 

      Dynamic 'moving-coil', Dynamic 'Ribbon' and Condenser

    • B. 

      LCD, LED and Plasma

    • C. 

      Carbon granule, acid and piezo

  • 4. 
    A Shure SM57 is what kind of microphone?
    • A. 

      A moving-coil dynamic

    • B. 

      A Ribbon mic

    • C. 

      A condensor

  • 5. 
    Dynamic moving coil mics have a coil of wire attached to the diaphragm.  This coil moves back and forth near a fixed magnet to produce the electrical signal.How does the extra weight on the diaphragm affect the microphone?
    • A. 

      It make the mic more sensitive to sound waves

    • B. 

      It makes the mic less sensitive to sound waves - especially to high frequency or 'bright' sound

  • 6. 
    Condenser microphones have no coil attached to the diaphragm.  Instead their diaphragm is formed from a capacitor - (akin to a electricity storing bucket).  This diaphragm is very light.A light diaphragm will make a condenser mic:
    • A. 

      Very sensitive to sound waves, including 'bright' high frequency waves

    • B. 

      Insensitive to sound

  • 7. 
    The Rode NT2, AKG Perception 170 and Neumann U87i are examples of what kind of microphone?
    • A. 

      Ribbon mic

    • B. 

      Dynamic moving-coil

    • C. 

      Condenser

  • 8. 
    Delicate acoustic instruments like acoustic guitars and violins often have a wide 'Dynamic range' (or volume difference between the quietest and loudest sound they produce), but also extended high frequencies in their sound characteristics.Which type of microphone would be the best to capture all the subtleties of the instruments?
    • A. 

      Dynamic moving coil mic

    • B. 

      Carbon granule mic

    • C. 

      Condenser mic

  • 9. 
    Which type of microphone has a 'Capacitor' forming part of its diaphragm and requires an electrical power supply to charge it up?
    • A. 

      A condenser mic

    • B. 

      A dynamic moving-coil

  • 10. 
    The 48 volt electrical power supply required by condenser microphone is inaudible but flows up the microphone lead.  This spooky phenomena lends it its name: 
    • A. 

      Phantom Power

    • B. 

      Ectopower

    • C. 

      Ghostly Gain
