Microphones and Educational Media.
This paper describes the types of microphones that are available for use in media production. Definitions of 16 words and phrases used to describe microphones are followed by detailed descriptions of the two kinds of microphones as classified by mode of operation, i.e., velocity, or ribbon microphones, and pressure operated microphones, which include crystal, moving coil, carbon granule, and capacitor microphones. It is noted that microphones are also classified according to the way they respond to sounds emanating from different directions: the omnidirectional microphone picks up sounds from all directions, whereas uni-directional microphones are sensitive to sounds from directly in front of the microphone. The latter include cardioid, supercardioid, and hypercardioid microphones. Specialty microphones are also mentioned: the parabolic reflector, lavalier, machine gun, tie-clip, zoom, and pressure zone microphones. A description of a conference microphone--i.e., one that maximizes the clarity of speech around a table--concludes the paper. (DB)
