摘要： A method at hearing aid and a hearing aid including a processor, a first microphone, a second microphone; wherein the first microphone is arranged to capture ear-canal sounds, and wherein the second microphone is arranged to capture ambient sounds; comprising: an acoustical model (511) configured to generate first values (hk) for the multiple frequency channels based on first parameters (G, A, l); and a statistical model (512) configured to generate second values (rk) for the multiple frequency channels based on values of second parameters (s1, s2, ··· , sn) and a set of basis vectors (u1, u2, ··· , un). An optimizer (509) is configured to obtain an optimized set of parameter values ({G, A, l, s1, s2, ··· , sn}*) including values of the first parameters and values of the second parameters; wherein the optimized set of parameter values is obtained by minimizing a difference between the first sound pressure levels (robs) and a combination of the first values (rk) and the second values (hk). An advantage is that sound pressure levels at the eardrum of the wearer of hearing aid can be accurately determined using a hearing aid with a microphone arranged to capture ear-canal sounds only at a distance from the ear drum.

摘要： 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 (2) driven by the electrical output signal and generating an acoustical signal into the ear canal (11) of a hearing aid user. The hearing aid comprises an ear plug part (1) 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 (1). The invention further provides a method for guiding a hearing aid user during insertion of an ear plug.

摘要： Disclosed herein, among other things, are apparatus and methods to provide improved connections for components of hearing assistance devices. Various embodiments include an apparatus including a receiver case configured to house a hearing assistance device receiver, the receiver case including a spherical receiver spout having an opening. The apparatus also includes a receptacle housing having a spherical socket adapted to mate with the spherical receiver spout to form a ball and socket connection. An insert within the spherical socket is configured to establish a retained interference fit with the opening of the receiver spout when the connection is formed so as to create an acoustic seal therebetween.

摘要： Included are a loudspeaker unit for generating sound waves, a sound conduit tube connected to the loudspeaker unit, and an ear tip connected to the sound conduit tube and having a shape having at least one opening. The sound conduit tube has a shape having: a sound hole having a first opening through which the sound waves generated by the loudspeaker unit enter, and a second opening from which the sound waves are released and to which the ear tip is connected; and a vent hole formed independently of the sound hole, and having a third opening through which a portion of the sound waves released from the second opening enters and a fourth opening from which the portion of the sound waves is released. The second opening of the sound hole and the third opening of the vent hole are connected to an identical opening of the ear tip.
