Abstract: Systems, devices and methods are provided for diotically presenting second-order gradient directional hearing aid signals. The present subject matter provides an improved signal-to-noise ratio, and presents a desired directional signal to each ear. One aspect is a hearing aid system. In one embodiment, the system includes a first microphone system in a first device and a second microphone system in a second device. The first microphone system has a first output signal, and the second microphone system has a second output signal. Each output signal includes a first-order directional signal. The system further includes a first receiver circuit and a second receiver circuit. The combination of the first output signal and the second output signal provides a diotic presentation of a second-order gradient signal to both the first receiver circuit and the second receiver circuit. Other aspects are provided herein.

Abstract: A hearing aid is provided with a switch that automatically switches the hearing aid input from a microphone input to a voice coil input in the presence of a magnetic field. The magnetic field can be generated by a magnet in a telephone handset.

Abstract: A hearing aid includes a microphone for providing an electrical signal representative of a received acoustic signal, a means for filtering the electrical signal and a means for automatic switching. Upon detecting a presence of a magnetic field, the means for automatic switching enables the means for filtering to modify a frequency response of the hearing aid to boost a low frequency gain and reduce a high frequency gain. Such filtering can be used with or without a telecoil. A hearing aid including a telecoil is configured with a preamplifier, a inductive element, and a switch control integrated onto a single common circuit board.

Abstract: Apparatus for use as an in-the-ear hearing aid. The apparatus includes a housing having a shell and a face plate, wherein the shell is molded to custom fit a hearing aid user's ear. A first non-directional microphone system is included having a first output signal representative of the sound received. A second non-directional microphone system is included having a second output signal representative of the sound received. A switch mechanism is included having an operator extending through the housing for switching the in-the-ear hearing aid between a non-directional mode and a directional mode. In the directional mode, the microphone system is adjustable between a cardioid and super cardioid polar output pattern.
