Abstract
Directivity has been found to be desirable in sound-collecting systems to improve the ratio of direct to generally reflected sounds and otherwise to discriminate against undesirable sounds. The bidirectional ribbon microphone is a pressure-gradient instrument, in which the response corresponds to the velocity component in a sound-wave. The pressure ribbon microphone is resistance controlled, and the response is a measure of the pressure component in a sound-wave. Combination of the outputs of the pressure and velocity ribbon microphones produces a unidirectional characteristic. This microphone has been found to be useful in sound motion picture recording, radio broadcasting, and sound reinforcing systems in which the desired sounds originate in front and the undesired sounds to the rear of the microphone.
