User adjustable weighting of sound classes of a hearing aid

A non-transitory computer-readable medium storing a computer program that, when executed, direct a processor of a hearing aid to:

• acquire a sound signal;
• classify the acquired sound signal with respect to predefined sound classes, wherein a raw class mixing weighting is determined, in which the sound signal is weighted with respect to the sound classes;
• process the sound signal with at least one actuator, wherein the actuator processes the sound signal based on an actual actuator parameterization, wherein each sound class comprises a sound class actuator parameterization for each actuator, and the actual actuator parameterization for each actuator is generated by mixing the sound class actuator parameterization of the sound classes based on the raw class mixing weighting;
• output the processed sound signal to be perceived by a user of the hearing aid;
• receive an adjustment demand for a sound property of the user of the hearing aid;
• modify the raw class mixing weighting into an adjusted class mixing weighting based on the adjustment demand, such that the sound signal is processed with the adjusted class mixing weighting;
• store the adjusted class mixing weighting with respect to the raw class mixing weighting as reference raw class mixing weighting;
• determine a further raw class mixing weighting;
• when the further raw class mixing weighting differs from the reference raw class mixing weighting only by at least a threshold, process the sound signal with the adjusted class mixing weighting stored with respect to the reference raw class mixing weighting.

A hearing aid, comprising:

• a classifier for classifying an acquired sound signal with respect to predefined sound classes, wherein a raw class mixing weighting is determined, in which the sound signal is weighted with respect to the sound classes;
• a sound processor for processing the sound signal with at least one actuator, wherein the actuator processes the sound signal based on an actual actuator parameterization, wherein each sound class comprises a sound class actuator parameterization for each actuator, and the actual actuator parameterization for each actuator is generated by mixing the sound class actuator parameterization of the sound classes based on the raw class mixing weighting;
• a modulator for outputting the processed sound signal to be perceived by a user of the hearing aid;
• a sound property adjuster for generating an adjustment demand for a sound property, when operated by the user of the hearing aid;
• wherein the hearing aid is adapted for
• modifying the raw class mixing weighting into an adjusted class mixing weighting based on the adjustment demand, such that the sound signal is processed with the adjusted class mixing weighting;
• storing the adjusted class mixing weighting with respect to the raw class mixing weighting as reference raw class mixing weighting;
• determining a further raw class mixing weighting;
• when the further raw class mixing weighting differs from the reference raw class mixing weighting only by at least a threshold, processing the sound signal with the adjusted class mixing weighting stored with respect to the reference raw class mixing weighting.
