Abstract: An acoustic sensor assembly includes a housing having an external-device interface and a sound port to an interior of the housing. An electro-acoustic transducer and an electrical circuit are disposed within the housing. The electro-acoustic transducer separates the interior into a front volume and a back volume, where the sound port acoustically couples the front volume to an exterior of the housing. The back volume includes a first portion and a second portion. The electrical circuit is electrically coupled to the electro-acoustic transducer and to the external-device interface. One or more apertures acoustically couple the first and second portions of the back volume and are structured to shape a frequency response of the acoustic sensor assembly.

Abstract: An acoustic motor assembly includes a substrate with a diaphragm ring that is integrally formed with the substrate. The diaphragm ring forms an opening extending through the substrate. The assembly also includes an electrically charged plate extending over the opening; a diaphragm extending over the opening and vertically displaced from the electrically charged plate; and a stitch coupling the electrically charged plate to the diaphragm. Sound energy creates a movement of the diaphragm, and the movement is effective to create an electrical signal representative of the sound energy.

Abstract: A method for measuring sound pressure at a tympanic membrane of a wearer's ear including a high frequency range with a hearing assistance device. The hearing assistance device comprises a processor connected to a sensor in the ear canal. The device provides a measure of the sound pressure level at the tympanic membrane of the wearer using a null frequency and a null Q measured at a distant position away from the tympanic membrane. The method does not require a precise knowledge of the ear canal, nor does it require an elaborate calibration step. In various embodiments, the present approach works at low and high frequencies.
