Systems and methods for generating and/or implementing a modified audiogram

A system for fitting a hearing device to a user, the system comprising:

• a memory storing instructions;
• and
• a processor communicatively coupled to the memory and configured to execute the instructions to:
• access a modified audiogram for the user of the hearing device, wherein the modified audiogram is based on a frequency lowering scheme that maps at least some audio frequencies included in a first set of audio frequencies to relatively lower audio frequencies to form a second set of audio frequencies, the modified audiogram indicating a set of modified hearing thresholds of the user at the first set of audio frequencies, which set of modified hearing thresholds is based on a set of hearing thresholds for the user at the second set of audio frequencies, wherein:
• the modified audiogram is generated by:
• applying the frequency lowering scheme to a set of reference hearing thresholds at the first set of audio frequencies to obtain frequency lowered reference hearing thresholds at the second set of audio frequencies;
• determining, based on the frequency lowered reference hearing thresholds and the set of hearing thresholds of the user at the second set of audio frequencies, the set of modified hearing thresholds at the second set of audio frequencies;
• and
• applying an inverse of the frequency lowering scheme to the set of modified hearing thresholds at the second set of audio frequencies to obtain the set of modified hearing thresholds of the modified audiogram at the first set of audio frequencies;
• determine, based on the modified audiogram and an input frequency-based target gain generation model, one or more target gain values for the user of the hearing device;
• and
• fit the hearing device to the user based on the one or more target gain values.
