23
Q
  • has two plates with a voltage between them
  • one of the plates is made of very light material and acts as the diaphragm
  • the diaphragm vibrates when struck by sound waves, changing the distance between the two plates
A

condenser (capacitor) microphone

24
Q
  • consisting of a coil of wire attached to a thin, lightweight diaphragm that vibrates in response to sound
  • the coil in turn vibrates within the field of the magnet and a signal is generated in proportion to the acoustic vibration the mic receives
A

dynamic microphone

25
omnidirectional
equally sensitive to sound from all directions, having no specific directionality
26
cardioid
has maximum sensitivity from the front, less sensitivity from the sides, and minimal sensitivity from the back of the diaphragm
27
hyper-cardioid
has focused sensitivity from the front, but sound from the rear is not suppressed quite as mcuh
28
A/B technique
spacing a pair of cardioid or omnidirectional microphones apart in such a way that they cover the space but do not create phase issues for each other (. | | )
29
XY technique
two cardioid microphones of the same type and manufacture with the two mic capsules wither as close as possible or within 12 inches of each other ( X )
30
ORTF technique
two cardioid microphones with a spacing of 17 sm between the microphone diaphragms and with an 110 degree angle between capsules ( \/ )
31
