Device and method for determining a hearing range

摘要

The object is to allow the adjustment of hearing aids without the use of sound-insulated acoustic booths. For this purpose provision is made for estimating a sound pressure level in front of the eardrum (5) from the sound pressure level in front of the hearing aid (2). Acoustic masking is determined from the estimated sound pressure level in front of the eardrum by means of a psycho-acoustic model. The actually measurable hearing range of the patient and therefore the optimum adjustment of the hearing aid can then in turn be determined from this.
