Abstract (en)
A method of determining parameters of a BTE hearing aid having at least one ITE microphone and at least one BTE microphone, the method includes: determining Head-Related Transfer functions HRTF l ( f ); determining a hearing aid related transfer function H l , i ITEC f of a i th microphone of the at least one ITE microphone for direction I; determining a hearing aid related transfer functions H l , j BTEC f of a j th microphone of the at least one BTE microphone; determining transfer functions G i IEC f of a i th cue filter of at least one cue filter filtering audio sound signals of the at least one ITE microphone; and determining transfer functions G j BTEC f of a i th cue filter of the at least one cue filter filtering audio sound signals of the at least one BTE microphone; wherein the transfer functions G i IEC f and the transfer functions G j BTEC f are determined using a processing unit based on equation: min G i IEC f , G i BTEC f ˆ‘ l = 0 L - 1 W l €– W f ¢ HRTF l f - £ i ¢ G i IEC f ¢ H l , i IEC f - jGjBTECfHl , jBTECf ¢ p .
