Calibration of Microphones by the Principles of Similarity and Reciprocity (A Reissue)

Document Thumbnail

As for ap-lication of the reciprocity principle to the calibration of a microphone, three transducers are used: the microphone to be calibrated, a reversible microphone-loudspeaker, and a loudspeaker. The absolute sensitivity of a microphone may be obtained from two experiments involving the three transducers and electrical standards of voltage, current, and frequency. For the application of the principle of similarity, two velocity microphones are used having linear dimensions in the radio 1:x. Under these conditions the configuration of the response characteristics will be the same, but shifted 1:x in frequency. The principles of similarity and reciprocity have been applied to the calibration of a commercial velocity microphone.
