Indoors, the sound pressure drop with distance eventually cease. However, the law still holds true for any normal microphone working-distance, and is also true for distances from loudspeakers up to about ten feet. A transducer which converts the electrical output of an amplifier into sound. The measure of a microphone's reaction to handling, bumping, and clanking. A microphone with high shock sensitivity will readily transmit the effects of cable friction, ring clankings, and finger thumpings to the sound system.
Microphones vary widely in their shock sensitivity.
A transducer which converts sound into an electrical output or voltage. An electronic device which permits combination of several signal inputs into a single output. Usually independent preamplifiers, tone and volume controls are provided for balancing input signals. A sound phenomenon, usually undesirable, which occurs when two or more microphones, each receiving the same input signal, are fed into the same mixer creating drastic and shifting voids in certain frequency bands. An acoustically transparent shield placed above the microphone diaphragm, many times around the exterior of the microphone, which sharply reduces the bad effects of explosive vocal sounds but does not affect desired microphone performance.
