Binaural hearing system and method
First Claim
1. A system for binaural signal processing, the system comprising:
- a first speaker and a second speaker respectively configured to be mounted proximal to, and to deliver respective first and second acoustic signals to, the left and right ears of a user;
a first microphone and a second microphone respectively configured to be mounted proximal to the left and right ears of a user; and
a binaural processing device for receiving respective first and second acoustic signals from each of the first and second microphones and for modifying each of the first and second acoustic signals to produce the modified first and second acoustic signals, wherein sound captured at both ears is used to modify the first acoustic signal to produce the modified first signal and sound captured at both ears is used to modify the second acoustic signal to produce the modified second signal, and wherein the binaural processing device is operable when distal from the left and right ears of the user;
wherein the first and second speakers, the first and second microphones and the binaural processing device are connected by a signal network configured to pass signals from the first and second microphones to the binaural processing device and from the binaural processing device to the speakers,wherein the signal network comprises a single wire chained bus loop having a chained configuration in which data from upstream on the single wire chained bus loop is recovered by each of the first and second speakers and the first and second microphones and re-modulated downstream onto the single wire chained bus loop, andwherein the first and second speakers are positioned downstream of the binaural processing device on the single wire chained bus loop, and the first and second microphones are positioned downstream of the first and second speakers on the single wire chained bus loop.

Abstract
A system (202) for binaural signal processing. A first speaker (210) and a second speaker (220) are respectively mounted proximal to, and deliver respective first and second acoustic signals to, the left and right ears of a user. A first microphone (212) and a second microphone (222) are respectively mounted proximal to the left and right ears. A binaural processing device receives signals from the microphones and, based on the microphone signals, determines the first and second acoustic signals. The binaural processing device operates at a distance from both the left and right ears of the user. The speakers, microphones and the binaural processing device are connected by a signal network.
