Abstract
The sound pressure level at the eardrum may be determined by constructing an optimized model of the ear canal and then calculating the simulated sound pressure level at the eardrum. The model is obtained by comparing real-ear-to-coupler differences between the sound pressure level measured at a fixed distance from a hearing instrument and a simulation of the measurement, optimizing the model by varying the length and/or diameter of the canal model, repeating the simulation and determination of simulated real-ear-to-coupler difference until the differences between the measured and simulated values are minimized. The optimized real-ear-to-coupler difference at the eardrum may then be determined and in turn the sound pressure level at the eardrum may be calculated. The sound pressure level at the eardrum may then be used to acoustically fit the hearing instrument to the person.
