  • Method for determining unbiased signal amplitude estimates after cepstral variance modification
    Patent number: 8208666
    Abstract: A method for determining unbiased signal amplitude estimates () after cepstral variance modification of a discrete time domain signal (s(t)), wherein the cepstrally-modified spectral amplitudes () of the discrete time domain signal (s(t)) are ?-distributed with 2{tilde over (?)} degrees of freedom. A bias reduction factor (r) is determined using the equation r 2 = ? ? ~ ? ? ? ? ( ? ~ ) - ? ? ( ? ) , where 2? are the degrees of freedom of the ?-distributed spectral amplitudes of the discrete time domain signal (s(t)) and ? ? ( x ) = - 0.5772 - ? n = 0 ? ? ( 1 x + n - 1 1 + n ) ; then the unbiased signal amplitude estimates () are determined by multiplying the cepstrally-modified spectral amplitudes () with the bias reduction factor (r) according to the equation =r.

  • Faceplate for hearing devices and method for producing a faceplate
    Patent number: 8204264
    Abstract: A faceplate of a hearing device housing with a component fitted in an opening of the faceplate and an associated method are provided. The faceplate is formed from a first material. When a predefinable distance between the support surface of the components in the opening and the surface facing away from the exterior of the faceplate is not reached, a second material is applied below the support surface to the surface of the faceplate such that the predefinable distance is produced. As a result, even with fitted components, for instance the volume controller or program selection switch, the mechanical stability of the faceplate is ensured.

  • Loss protection system for hearing aid devices
    Patent number: 8189835
    Abstract: The miniaturization and wearing comfort of hearing aid devices increasingly runs the risks of a hearing aid device worn on or in the ear of a user getting lost without user realizing. The invention relates to a hearing aid device system comprising a first and a second hearing aid device which is worn on the head or body of a user to provide an electronic loss protection system which is reliable and easily manageable for a user. The first hearing aid device controls a presence of a radio link and/or a signal level of a signal sent from the second hearing aid device and received in the first hearing aid device. If the radio link breaks or the signal level drops below a threshold value, an information signal is generated by the first hearing aid device to inform the user of the loss of the second hearing aid device.

  • Ear mold with vent opening through outer ear and corresponding ventilation method
    Patent number: 8189836
    Abstract: A method and hearing aid mold are provided for a hearing device with a first segment for insertion into the auditory canal of the user, a second segment, which projects into the concha of the user when inserted, and a vent, which runs from the first segment into the second segment. A vent opening, which may be enclosed by a titanium ring, is directed in the second segment toward the outer ear of the user, so that an exchange of air can be achieved between the auditory canal and the rear of the outer ear through an opening in the outer ear. Ventilation of the auditory canal from the rear of the outer ear reduces the risk of feedback.

  • Hearing aid with UV sensor and method of operation
    Patent number: 8184837
    Abstract: A hearing aid and a method for operating a hearing aid include a signal processing device operable by using different signal processing parameters and a UV sensor connected to the signal processing device. The signal processing device can set at least one signal processing parameter as a function of an output signal of the UV sensor. At least one predetermined signal processing parameter can be set in each case for within and outside of enclosed spaces. It is possible to reliably distinguish between environmental situations within and outside of enclosed spaces by using the UV light intensity in the environment to be measured by the UV sensor, so that the method of operation of the hearing aid, e.g. of an aural program, is advantageously automatically matched to these two environmental situations.

  • Hearing aid with a drop safeguard
    Patent number: 8175305
    Abstract: A hearing aid with a drop safeguard has an accelerometer, an electrical circuit, and a memory. The accelerometer generates an electrical signal in dependence on an acceleration of the hearing aid. The signal is transmitted to the electrical circuit which uses this to determine a jerky acceleration of the hearing aid. The electrical circuit saves the respectively current settings of the hearing aid to the memory in the case of a jerky acceleration of the hearing aid. After the hearing aid is dropped, the settings can be reconstructed from the memory so that as a result this prevents the settings of the hearing aid from being changed.
