    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.

  • Patent number: 8161816
    Abstract: A method and apparatus for administering a hearing test that emits a test sound with changing volume with respect to elapsed time. The volume changes according to a pre-determined relationship between the volume and elapsed time. The hearing test utilizes the elapsed time until a subject signals the test sound is audible, and the pre-determined relationship, to determine the subject sound pressure level threshold for the test sound.

    Abstract: Disclosed is a method and system for allowing a recipient of a hearing aid device, and in one aspect, a bilateral hearing aid system, to locate the source of a sound signal about the recipient. The method uses localisation cues in the sound signal and modifies these to provide useable localisation cues to generate a stimulating signal for application to the recipient. In one example, a detected localisation cue such as an interaural level difference (ILD) is transposed to a lower frequency.

  • Patent number: 8150044
    Abstract: Methods for personalized listening which can be used with an earpiece are provided. A method includes capturing ambient sound from an Ambient Sound Microphone (ASM) of an earpiece partially or fully occluded in an ear canal, monitoring the ambient sound for a target sound, and adjusting by way of an Ear Canal Receiver (ECR) in the earpiece a delivery of audio to an ear canal based on a detected target sound. A volume of audio content can be adjusted upon the detection of a target sound, and an audible notification can be presented to provide a warning.

  • Patent number: 8150049
    Abstract: The present invention relates to a digital hearing aid, which models the structures of external ear canals, sizes and shape characteristics of which differ between respective persons, obtains resonance gains generated due to the structural characteristics of the external ear canals, and performs digitization and signal processing to allow the resonance gains to be used as the gain factors of the digital hearing aid, and thus applies the gain factors to digital signal processing units. Further, the present invention proposes a gain obtainment unit capable of taking both resonance gains, generated due to the structural characteristics, and gains, obtained through a hearing test, into account, thus reducing the time required for gain fitting and possible errors, and optimizing the performance of the digital hearing aid for each individual.

  • Publication number: 20120076313
    Abstract: The adjustment of a hearing device is to be improved and configured in a more user-friendly fashion. To this end, a method is proposed whereby the hearing device is set individually to the user and is inserted at least partially into the auditory canal of the user. Finally an in-situ measurement of the acoustic impedance of the auditory system of the user including at least part of the auditory canal of the user is implemented with a tympanometric method. An automatic correction of the individual setting of the hearing device can take place on the basis of the results of the in-situ measurement.

  • Patent number: 8144904
    Abstract: Sound quality and speech comprehensibility are to be improved for hearing device wearers when watching television. Provision is made for this purpose to record acoustic signals at a recording site on a data medium. The acoustic signals are recorded simultaneously with a first microphone as a first recording. The data medium is played back on an individual playback device in an individual environment. Here the signal played back from the data medium is re-recorded as a second recording with a second microphone. The two recordings are connected to each other, subtracted in particular, and the result is used to adjust a hearing device program. It is thus possible to take into account individual acoustic environmental conditions in the hearing device program.

  • Patent number: 8139778
    Abstract: The training of a hearing apparatus in respect of an individual adjustment is to be developed in a more user-friendly manner. To this end, provision is firstly made to automatically classify a hearing situation, to adjust a parameter of the signal processing facility of the hearing apparatus and to automatically learn the adjusted parameters for the current hearing situation. A temporal monitoring of the steps “classifying” and “adjusting” is however carried out here and the automatic learning is only triggered if the classified hearing situation and the adjustment of the parameters have not changed over a predetermined time period. This not only simplifies the training, but also enables a more rapid training by means of automatically triggered training events.

  • Patent number: 8139779
    Abstract: The aim of the invention is to make using a hearing device and in particular a hearing aid more comfortable and more effective for the user. To this end the setting of a portable hearing device is to be checked. First the acoustic data of a sound from the environment of the hearing device is recorded and/or determined simultaneously with the setting of the hearing device with at least one setting value. The setting of the hearing device is evaluated against the chronologically matching, recorded acoustic data in the hearing device using at least one predeterminable criterion. If necessary, the hearing device outputs an appropriate message. By this means a hearing aid wearer can, for example, be alerted to contact an acoustician, if the settings he made on the hearing aid are not effective.
