Abstract (en)
[origin: EP3783921A1] A method for adjusting a frequency dependent gain of a hearing device (10) comprises: receiving an amplification level (38) selected by a user of the hearing device (10); selecting offset gain values (40) for frequencies in a bass range (34) based on the amplification level (38); reading fitting gain values (30) for the frequencies stored in the hearing device (10), wherein the fitting gain values (30) have been selected to compensate a hearing loss of the user; determining direct sound indicator values (32) for the frequencies, wherein an direct sound indicator value (32) for a frequency specifies a level of direct sound in front of an ear drum in an ear canal of the user at that frequency; setting an adjusted gain value (36) in each frequency depending on the offset gain value (40), the fitting gain value (30) and the direct sound indicator value (32); applying the adjusted gain values (36) to an amplifier (20) of the hearing device (10), such that a sound signal in each frequency is amplified with the corresponding adjusted gain value (36).
