Title: USER ADJUSTABLE WEIGHTING OF SOUND CLASSES OF A HEARING AID
Abstract:
A method for operating a hearing aid (10) comprises: acquiring a sound signal (20); classifying the acquired sound signal (20) with respect to predefined sound classes (36), wherein a raw class mixing weighting (46) is determined, in which the sound signal (20) is weighted with respect to the sound classes (36); processing the sound signal (20) with at least one actuator (30), wherein the actuator (30) processes the sound signal (20) based on an actual actuator parameterization (32), wherein each sound class (36) comprises a sound class actuator parameterization (38) for each actuator (30), and the actual actuator parameterization (32) for each actuator (30) is generated by mixing the sound class actuator parameterization (38) of the sound classes (36) based on the raw class mixing weighting (46); and outputting the processed sound signal (24) to be perceived by the user of the hearing aid (10). The method further comprises: receiving an adjustment demand for a sound property (42) of a user of the hearing aid (10); and modifying the raw class mixing weighting (46) into an adjusted class mixing weighting (48) based on the adjustment demand, such that the sound signal (20) is processed with the adjusted class mixing weighting (48).
