microphones Flashcards
acoustic energy
electric signal
dynamic
not affected by climate easily, higher levels of snd, rugged, cheaper, magnetic cable
diaphragm
thin, movable membrane that moves with snd
Moving coil
diaphragm moves it
condenser
natural snd, excellent freq. response, high sensitivity 48v, can be fragile, uses conductive plates
ribbon
technically dynamic, both diaphragm and transducer, very fragile, 10x thinner than hair
stereo mic
two capsules in one, mono or stereo, good for spatial image
digital/USB
has pre-amp, plug in and go, great for quick computer needs
shotgun mic
long, directional, interface tube to reject unwanted snds, condenser
boundary mic
pressure zone, plate mounted mic, place on surfaces, discrete and for large areas
lavalier/body mic
super discrete, wireless and hands free, great for stage/film
binaural
mimic human ears, meant for audience to wear headphones, great for spatial snd
Guitar Pickups
detects string vibrations and harmonics
Polar Patterns
cardioid (unidirectional), figure-eight (bidirectional), omnidirectional
Proximity effect
hand cupping impedes pattern, boost low end freq.
