| 摘要 |
The invention relates to a digital hearing aid system comprising a signal path with an input transducer, a signal processor and an output transducer, where a part of the system is intended for delivering sound into an ear canal of a hearing aid user, where this part leaves the ear canal with an non obstructed cross sectional area corresponding to a vent channel with a diameter of at least 3 mm, and where the signal path is designed to have a signal delay less than 8 ms. Preferably the hearing aid signal path furthermore comprises means for providing an adaptive feedback compensation. Furthermore the signal processor is adjusted to provide increased gain in low frequency areas.
