Patent ID: 7783064

Claim:
A hearing aid system, comprising: a left hearing aid having a first input signal for supplying the left ear of a hearing aid user; and a right hearing aid having a second input signal for supplying the right ear of the hearing aid user, wherein the left and right hearing aids each include: a transmission unit for transmitting the input signal of the respective hearing aid to the respective other hearing aid; and a signal processing device for generating in the respective hearing aid a first and second acoustic mono signal from a side-selective weighed average of the first and second input signals, wherein the first acoustic mono signal is generated in the left hearing aid by averaging the first and second input signals after significantly weighting the first input signal in the left hearing aid, and wherein the second acoustic mono signal is generated in the right hearing aid by averaging the first and second input signals after significantly weighting the second input signal in the right hearing aid, providing side-selectivity in each respective hearing aid such that the first acoustic mono signal lies closer to the first input signal for the left hearing aid and the second acoustic mono signal lies closer to the second input signal for the right hearing aid.
