A hearing aid () comprising a receiver () and at least one first microphone for transforming an acoustic signal surrounding a hearing aid user into an electrical signal, where the hearing aid comprises an ear plug part prepared for fitting tightly into the car canal () of a hearing aid user such that an inner volume is formed in the inner part of the ear canal between the car plug part and the car drum of the hearing aid user. The car plug part comprises a second microphone () arranged for transforming an acoustic signal in the volume into an electrical signal. The hearing aid comprises estimating means for estimating the effective size of the air leak between the inner volume and the surroundings based on the acoustical signal detected in said volume by said second microphone () from a known acoustical signal below 1000 Hz generated by the receiver. The hearing aid further comprises notification means for notifying the hearing aid user if the size range of the air leak is outside a predefined range.

Hearing aid with means for estimating the ear plug fitting

A hearing aid comprises a microphone for transforming an acoustic signal surrounding a hearing aid user into an electrical signal, a signal processing means for processing the electrical signal into an electrical output signal and to a receiver () driven by the electrical output signal and generating an acoustical signal into the ear canal () of a hearing aid user. The hearing aid comprises an ear plug part () prepared for being arranged in the ear canal of a hearing aid user. The hearing aid comprises sound generation means for generating an acoustic guiding signal to be provided for a limited period through said receiver during insertion of the ear plug part into the ear canal, in order to be applied by the hearing aid user to optimize the positioning of the ear plug part (). The invention further provides a method for guiding a hearing aid user during insertion of an ear plug.

Hearing aid with guiding means for insertion

The present invention relates to isolated nucleic acid sequences encoding polypeptides having pyranose oxidase activity. The invention also relates to nucleic acid constructs, vectors and host cells containing the nucleic acid sequences as well as recombinant methods for producing the polypeptides.
