Patent ID: 7369669

Claim:
A hearing aid system, comprising: a first microphone system positioned in a first device for receiving sound and providing a first output signal representative of the sound received, wherein the first output signal includes a first-order gradient directional hearing aid signal from the first microphone system; a second microphone system positioned in a second device for receiving sound and providing a second output signal representative of the sound received, wherein the second output signal includes a first-order gradient directional hearing aid signal from the second microphone system; a first receiver circuit positioned in the first device for aiding hearing in a first ear of a wearer, the first receiver circuit being connected to the first microphone system to receive the first output signal and connected to the second microphone system to receive the second output signal, wherein the first receiver circuit includes a first receiver and a first signal processing circuit, and the first signal processing circuit includes a first summer for summing the first-order directional hearing aid signal from the first microphone system and the first-order directional hearing aid signal from the second microphone system to provide a second-order gradient signal to the first receiver; and a second receiver circuit positioned in the second device for aiding hearing in a second ear of a wearer, the second receiver circuit being connected to the first microphone system to receive the first output signal and connected to the second microphone system to receive the second output signal, wherein the second receiver circuit includes a second receiver and a second signal processing circuit, and the second signal processing circuit includes a second summer for summing the first-order directional hearing aid signal from the first microphone system and the first-order directional hearing aid signal from the second microphone system to provide the second-order gradient signal to the second receiver.
