Patent number: 8848953Abstract: A method for the operation of a hearing device with at least one receiver includes carrying out a fixed second frequency shift of an electrical receiver signal supplying the receiver or of a predefinable frequency range of the receiver signal and a variable first frequency shift of the receiver signal or of a predefinable frequency range of the receiver signal. The first frequency shift is changed depending on the occurring feedback. A frequency shift which effectively prevents feedback is advantageously carried out, while artifacts of the frequency shift are minimized.Type: GrantFiled: June 28, 2011Date of Patent: September 30, 2014Assignee: Siemens Medical Instruments Pte.

Patent number: 8811641Abstract: A hearing aid device has an input converter for receiving an input signal and converting the signal into an electrical input signal, a signal processing unit for processing and frequency-dependent amplification of the electrical input signal and generating an electrical output signal, an output converter for converting the electrical output signal into an acoustic output signal, and a sound detector facility for identifying sounds in a signal. Facilities increase an amplification above a normal amplification for a frequency range in which an identified sound contains signal components. Further facilities set the normal amplification of an electrical input signal in dependence on a signal frequency. The amplification is restricted to a maximum amplification in a specific frequency range. The amplification exceeds the normal amplification or the maximum amplification for the duration of the identified sound and at most for a duration which lies below a setting time of a feedback whistling.Type: GrantFiled: April 2, 2012Date of Patent: August 19, 2014Assignee: Siemens Medical Instruments Pte.

Patent number: 8737656Abstract: A hearing device has a signal-processing apparatus for processing an input signal into an output signal, and a feedback-canceller apparatus for reducing feedback artifacts on the basis of the input signal and the output signal. The feedback-canceller apparatus has an adaptive, first filter, for establishing a set of filter coefficients for a predefined feedback situation. The feedback-canceller apparatus is configured to store the set of filter coefficients. It has at least one second filter, which can be operated directly parallel to the first filter on the basis of the stored set of filter coefficients. The adaptive, first filter can be continuously adapted to a current feedback situation, and the feedback-canceller apparatus is configured such that in the current feedback situation it automatically selects either the first or the second filter. As a result, it generally only requires a simple switchover, but not a complete adaptation.Type: GrantFiled: February 28, 2011Date of Patent: May 27, 2014Assignee: Siemens Medical Instruments Pte.

Method for improving the comprehensibility of speech with a hearing aid, together with a hearing aid
Patent number: 8644538Abstract: The understanding of speech is to be improved in cases of hearing loss in which certain frequency ranges can no longer be perceived even at high volume or amplification, as applicable. A frequency transposition is performed on an input signal coming into a hearing aid and specific features of an electrical input signal are detected and a transposed signal is filtered as a function of the specific features detected in the electrical input signal. The hearing aid provides appropriate facilities for detecting specific features of the electrical input signal and filtering facilities for filtering the transposed signal. The objective of this is to detect particular properties of the input signal, in particular signal properties which are characteristic of fricatives, which may possibly be lost as a result of the frequency transposition, and at least partially to restore them in the transposed signal.Type: GrantFiled: April 2, 2012Date of Patent: February 4, 2014Assignee: Siemens Medical Instruments Pte. Ltd.Inventors: Sebastian Pape, Maja Serman -
Patent number: 8588444Abstract: A method operates a hearing device having at least two omnidirectional microphones emitting microphone signals and a detection unit for defining acoustic feedback. The method includes connecting a first electrical connection of the microphones to one another in order to form a first signal with directional effect, an adjustment of the directional effect of the first signal such that the acoustic feedback in the first signal is maximized, and an analysis of the first signal by the detection unit for defining the acoustic feedback. It is advantageous that the feedback can be detected by a signal with an improved signal-to-noise ratio. Feedbacks are therefore recognized more reliably and more rapidly.Type: GrantFiled: December 22, 2010Date of Patent: November 19, 2013Assignee: Siemens Medical Instruments Pte.

Patent number: 8433086Abstract: A hearing apparatus and in particular a hearing device is to be provided, in which interference noises are to be reduced however as natural an acoustic image as possible is consequently retained. To this end, a hearing apparatus with a first signal processing channel, into which a noise reduction device is integrated and a second signal processing channel, which has the same input as the first signal processing channel and into which no noise reduction device, but instead a level limitation device is integrated, is proposed. An adding device adds the output signals of both signal processing channels to form an overall output signal. A passive input level-dependent noise reduction can thus be realized, with which quiet signals can be heard again despite the noise reduction.Type: GrantFiled: June 26, 2008Date of Patent: April 30, 2013Assignee: Siemens Medical Instruments Pte. Ltd.Inventors: Heike Heuermann, Sebastian Pape

Patent number: 8396236Abstract: Feedback in a hearing device and, more particularly, in a hearing aid should be compensated for before it becomes audible. To this end, a method is proposed for compensating for a feedback signal in a hearing device with an input-transducer apparatus, a signal-processing apparatus and an output-transducer apparatus, in which method a feedback signal is compensated for, which feedback signal is fed back to the input-transducer apparatus from the output-transducer apparatus or the signal-processing apparatus. More particularly, a probability of having a plurality of notches, equally spaced apart from one another, in the spectrum of an input signal is established, which input signal originates directly from the input-transducer apparatus or which is a difference signal between the signal directly from the input-transducer apparatus and a compensation signal serving for compensation. The compensation is modified or the signal-processing apparatus is amplified as a function of this established probability.Type: GrantFiled: February 9, 2011Date of Patent: March 12, 2013Assignee: Siemens Medical Instruments Pte.
