Classification: CPC H | IPC H

Claim 0:
1. A method comprising:
determining a least squares estimate and a reduced dimensionality estimate that both estimate a relative transfer function between secondary path measurements and associated acoustic transducer-to-eardrum responses of a hearing device;
determining a cutoff frequency for an individual based on a secondary path measurement performed on the individual;
determining a first acoustic transducer-to-eardrum response below the cutoff frequency using the secondary path measurement and the least squares estimate;
determining a second acoustic transducer-to-eardrum response above the cutoff frequency using the secondary path measurement and the reduced dimensionality estimate; and
predicting a sound pressure level caused by the hearing device at an eardrum of the individual using the first and second acoustic transducer-to-eardrum responses.
