Patent ID: 7936890

Claim:
A hearing aid system for generating auditory spatial cues, comprising: a first microphone unit configured to convert sound received at a first microphone to a first electric signal on a first output and received at a second microphone to a second electric signal on a second output; a first delay unit connected to said first output and configured to delay said first electric signal; a first calculation unit connected to said first delay unit and said second output and configured to sum said delayed first electric signal and said second electric signal and to generate a first summed signal; a processor unit connected to said first calculation unit and configured to process said first summed signal and to generate a processed signal; and a speaker configured to convert said processed signal to a processed sound, wherein said first microphone and said second microphone are separated by a predetermined first distance, and said first delay unit is adjusted to provide a predetermined first time delay of said first electric signal causing said first calculation unit to generate a first auditory spatial cue representing a first spatial dimension in said first summed signal to a user.
