Abstract: While anechoic microphone frequency response is a common specification, microphones in use for dialogue are strongly influenced by their relative position to the talker. In this experiment, one reference microphone type and position is taken as representing the correct response for the talker, and other microphones and methods for their use are compared with the reference. Among the positions and types tested are those normally used on a boom for film and television use, and a lavalier. Equalization is designed to minimize the differences between each type and the reference, and in some cases, up to ten parametric bands are necessary to produce a response that is about ±1 dB of the reference over the voice range. Several acoustic conditions were included in the survey, as well as the effects of windscreens.
