Abstract
A method of fitting a hearing aid gain (100) adapted to take the vent effect into account. The invention is also directed at a hearing aid fitting system adapted to carry out said method.
Claims12
A method of fitting a hearing aid gain, comprising the steps of:
- providing a plurality of sets of measured values of an acoustic feedback metric and a vent effect based on inserting a hearing aid of a specific type into a plurality of at least one of real ears and artificial ears;
- using the plurality of sets of measured values to determine a relationship between the acoustic feedback metric and the vent effect for said specific type of hearing aid;
- measuring an acoustic feedback metric for a hearing aid to be fitted, when inserted in a user's ear;
- estimating a vent effect for the hearing aid to be fitted based on the determined relationship and the measured acoustic feedback metric;
- determining a correction gain based on the estimated vent effect;
- and
- incorporating the correction gain in the gain of the hearing aid to be fitted, wherein the hearing aid to be fitted is of said specific type.
4 more elements
A hearing aid system operationally connected with a server that is adapted to:
- receive from a multitude of hearing aid systems a measured acoustic feedback metric and the specific hearing aid type,
- use the received acoustic feedback metrics to optimize a hearing aid system setting based on a statistical analysis of the measured acoustic feedback metric,
- provide the optimized setting to the hearing aid system.
