Method and system for fitting a hearing aid

A computer program containing executable program code which, when executed on a computer, executes a method for fitting a hearing aid gain, comprising the following steps for at least one frequency band:

• measuring a loop gain of an in-situ hearing aid;
• estimating an effective vent parameter for the hearing aid by determining that vent parameter as said effective vent parameter that provides the best fit between a number of predetermined loop gains and the measured loop gain;
• calculating a correction gain based on said effective vent parameter;
• and
• correcting said hearing aid gain by means of said correction gain.
