Abstract
A highly discreet and accurate voice pickup device includes a standard miniature pressure gradient type microphone element provided and mounted very close to the side of the user's head, preferably near the user's ear. The microphone element is oriented so that its direction of maximum sensitivity is parallel to the side of the user's head, and points toward the user's mouth so that it will pick up the user's speech sounds as the sounds diffract and travel along the side of the user's face and head, to the microphone element. The microphone element can be configured with low pass networks at front and rear ports of the microphone element, which cooperate with air volumes within the microphone to provide additional directional properties that advantageously vary with frequency and further enhance the noise-rejection capability of the microphone element.
