Patent ID: 8019103

Claim:
A hearing aid comprising: a first microphone for conversion of an acoustic sound signal into a first electronic audio signal, a first A/D-converter for conversion of the first electronic audio signal into a first digital signal, a signal processor for digital signal processing of the first digital signal into a digital output signal, including amplification of the first digital signal for compensation of a hearing loss of a wearer of the hearing aid, a D/A converter for conversion of the digital output signal into an audio output signal, and a receiver for conversion of the audio output signal into an acoustic audio signal for transmission towards an eardrum of the wearer of the hearing aid, wherein the signal processor is further configured to determine a ratio between a first power of the first digital signal at first frequencies and a second power of the first digital signal at second frequencies to thereby detect a presence of wind noise wherein the first frequencies includes a frequency that is lower than a frequency in the second frequencies.
