Abstract
A binaural hearing aid system (100) is adapted to provide binaural beats to a hearing aid user. The invention further provides a method of generating binaural beats.
Claims20
A binaural hearing aid system comprising a first hearing aid, a second hearing aid, a wireless link component and a synchronizer,
- wherein said first hearing aid comprises
- a first acoustical-electrical transducer for transforming an acoustic signal into a first audio input signal;
- a first processor configured to amplify a first processor input signal and provide a first processor output signal;
- a first electrical-acoustical output transducer adapted for converting the processor output signal into sound;
- a first sound generator adapted for providing a first synthesized signal;
- a first frequency shifter adapted for shifting a first electrical audio signal in frequency hereby providing a first frequency-shifted electrical audio signal, wherein said first electrical audio signal is one of said first audio input signal and said first synthesized signal;
- a first summer adapted for adding the first frequency-shifted electrical audio signal to the other one of said first audio input signal and said first synthesized signal to provide said first processor input signal;
- wherein the
- wireless link component is configured for establishing a wireless connection between said first and said second hearing aid of the binaural hearing aid system;
- and wherein the
- synchronizer is adapted for synchronizing the operation of said first hearing aid and said second hearing aid at least with respect to said first frequency-shifted electrical audio signal.

A method of providing binaural beats comprising the steps of:
- providing a first electronic device and a second electronic device adapted for wearing at respective ears of a user;
- generating a first electrical audio signal in the first electronic device and a second electrical audio signal in the second electronic device;
- synchronizing said first electrical audio signal with said second electrical audio signal;
- and
- frequency shifting said first electrical audio signal by a fixed frequency relative to the second electrical audio signal and selected to provide a binaural beat;
- wherein said step of generating said first and second electrical audio signals comprises the steps of:
- generating a pseudo-random number, calculating parameters of a tone from a generated pseudo-random number, generating an electrical audio signal according to the calculated parameters and controlling said generation of the electrical audio signal by using control parameters calculated from a generated pseudo-random number.
