Definitions

  • the present invention relates to a sound signal processing method of the kind set forth in the preamble of claim 1 and a device for implementing such a method.
  • control parameters may comprise, but are not limited to, the output signal from the signal processor unit, time of day, ambient temperature, ambient air humidity, ambient light, telecoil detection, voice recognized spoken control words, pulse rate of the user, etc., all of these parameters being supplied to the programmable controller in order to detect different conditions with respect to e.g. the environment, the "state" of the user, etc.
  • the different parameters may initially influence the generated control parameters according to a preprogrammed function in the programmable controller, but will during a training period be changed and adjusted in accordance with the preferences of the user, as communicated to the programmable controller, thereby providing a trainable performance of the signal processing, in which the starting point is fixed, but the adjustments are unknown and the final programming is unlimited.
  • the signal processing method is preferably implemented in micro-processor technology and comprises fixed and adjustable programming, the adjustments of the adjustable programming being normally performed by the user possibly in cooperation with a fitter.
  • the digital signal processor unit may be implemented in micro-processor technology as a fixed calculating structure, e.g. a FIR-filter, an IIR-filter, a neural network or the like, with variable parameters controlled by the programmable controller which is preferably implemented in the same micro-processor as the signal processing unit.
  • the programmable controller may perform functions like spectral analysis, statistical analysis, mathematical functions, logical functions, etc., in order to generate appropriate control parameters for the digital signal processor unit.
  • the hearing aid shown in Figure 1 includes a main signal path comprising a microphone 1, an A/D-converter 2, a digital signal processor unit 3, a D/A-converter 4 and a telephone 5.
  • the processing in the digital signal processor 3 is controlled by several control parameters supplied from a programmable controller 6.
  • the programmable controller 6 generates the control parameters continuously and dynamically as a function of the digitized version of the signal to be processed, delivered by the A/D-converter 2.
  • the programmable controller 6 is also receiving the digital output signal from the digital signal processor unit 3 for influencing the generating of control parameters for the digital signal processor 3. Further parameters, as mentioned above, may be supplied to the programmable controller 6 for influencing the generating of control parameters.
  • the digital signal processor unit 3 is understood to be a fixed calculating structure, e.g. a FIR-filter, an IIR-filter, a neural network or the like. It is essential when choosing this fixed calculating structure with adjustable parameters that the structure can change in characteristics by adjusting the parameters so that the desired signal processing can be achieved.
  • a fixed calculating structure e.g. a FIR-filter, an IIR-filter, a neural network or the like. It is essential when choosing this fixed calculating structure with adjustable parameters that the structure can change in characteristics by adjusting the parameters so that the desired signal processing can be achieved.
  • the main signal path is of a constant nature comprising A/D-, D/A-converter and the digital signal processing unit 3 which once and for all can be constructed to have sufficient accuracy and resolution to achieve the desired high signal quality.
  • New forms of signal processing will only indirectly influence the signal path by being implemented in the programmable controller 6 which means that the system will not have to be redesigned with respect to signal/noise-ratio etc., for each new algorithm to be added.
  • the adjustment of the hearing aid will possibly comprise a basic adjustment of the hearing aid in order to compensate for the hearing loss of the patient, which adjustment will be based on traditional audiologic diagnostics and/or other, possibly individual characteristics like lifestyle, personal qualities, etc., and followed by further adjustments of the system in the user's own environment in accordance with the user's preferences. The aim of these adjustments will be to provide the user with a sound perception in accordance with the users preferences under different conditions.
  • the system for fitting the hearing aid will comprise the physical hearing aid and possibly stationary equipment at the fitter laboratory and user portable equipment for use in the user's own environment.
  • the communication between the user and the fitting equipment may be performed by voice control, manual keyboard control, physiologic activity control, using electrodes or other sensors connected to the user, etc., and the communication between the fitting equipment and the hearing aid may be wired or wireless.
  • FIG. 2 schematically shows the signal processing system.
  • the programmable controller 6 is built up of three components, a pre-processing block 7,8, a neural network block 9 and a post-processing block 10.
  • the signal processing unit 3 is composed of a filter block 11 succeeded by a gain block 12, both getting parameters from the post-processing block 10.
  • the pre-processing block 7,8 the overall rms-energy (RMS Total ) 8 of the input signal and the ratio between energy at high and low frequencies (Tilt) 7 in the input signal are estimated.
  • the control parameters RMS Total and Tilt change the processing parameters for the signal processing unit 3, i.e. the filter coefficients and the gain scaling, dynamically and continuously.
  • the individual adjustment of the system performance to fulfil the user's preference is carried out by training the neural network 9 to match the individual requests according to the control parameters.
  • the achieved functionality is schematically shown in Figure 3.
