Definitions

  • the invention relates to a portable in or on the ear of a hearing aid wearer hearing aid with an input transducer for receiving an input signal and conversion to an electrical input signal, a signal processing unit for processing and amplification of the electrical input signal, an output transducer for converting the processed and amplified electrical input signal in one of the Hearing aid carrier as an audible signal perceptible output signal and an operating device for switching on and off of the hearing aid and for setting a value for at least one signal processing influencing parameters by the hearing aid wearer, wherein means for storing the set when the hearing aid device value of the parameter in the turned off hearing aid and means for automatically setting the stored value of the respective parameter after turning on the hearing aid are.
  • the invention relates to a method for operating such a hearing aid.
  • an input signal is recorded by means of an input transducer and converted into an electrical input signal.
  • an input transducer usually serves as an input transducer at least one microphone which receives an acoustic input signal.
  • Modern hearing aids often comprise a microphone system with a plurality of microphones in order to achieve a direction dependent on the direction of arrival of acoustic signals reception, a directional characteristic.
  • the input transducers may also include a telecoil or antenna for receiving electromagnetic input signals.
  • the input signals converted by the input transducer into electrical input signals are fed to a signal processing unit for further processing and amplification. The further processing and amplification is done to compensate for the individual hearing loss of a hearing aid wearer usually in response to the signal frequency.
  • the signal processing unit outputs an electrical output signal, which is fed via an output transducer to the hearing of the hearing aid wearer, so that the latter perceives the output signal as an acoustic signal.
  • output transducers usually listeners are used, which generate an acoustic output signal.
  • output transducers for generating mechanical vibrations are also known, which directly excite certain parts of the ear, such as the ossicles, to vibrate.
  • output transducers are known which directly stimulate neurons of the ear.
  • parameters relating to signal processing can usually be set by the hearing aid wearer.
  • Such parameters are, for example, the current hearing program for adapting the signal processing in the hearing aid to different environmental situations or the volume setting.
  • the set values of the relevant parameters are usually stored in digital form in a memory.
  • the value of a parameter may also be binary, for example if the parameter merely indicates whether a particular algorithm (e.g., smoke suppression, noise cancellation, etc.) or a particular function (e.g., directional microphone) is on or off.
  • the adjustment is carried out either by directly attached to the hearing aid controls or by means of a remote control for the hearing aid in question.
  • the central component of the signal processing unit of a modern hearing aid is a digital signal processor (DSP).
  • DSP digital signal processor
  • the values of adjustable parameters which influence the signal processing must first be read from a memory after being switched on and transmitted to the digital signal processor.
  • standard settings for the parameters adjustable by the hearing aid wearer are also determined. It also determines in which hearing program the hearing aid is operated by default after switching on. Once set in this way standard settings for the respective hearing aid wearer are then automatically set after each turn on the hearing aid, that is, read from a non-volatile memory and transferred to the digital signal processor.
  • the known hearing device comprises a memory device for storing the values of the parameters which are valid before the hearing device is switched off and for setting these values after the hearing device has been switched back on.
  • the object of the present invention is to simplify the operation of a hearing aid.
  • the basic idea of the invention is based on the fact that the values of the parameters of the hearing aid device which can be set by the hearing aid wearer are stored in digital form in a nonvolatile memory as long as the hearing aid is switched off. After switching on, the numerical values stored in this way are activated immediately so that the signal processing in the hearing aid device takes place immediately after switching on again with exactly the values for the relevant parameters that were valid before the hearing aid was switched off.
  • This has the advantage that the hearing aid automatically takes over the last selected by the hearing aid wearer settings after switching on again and this therefore not again manually for him pleasant settings must select by operating controls.
  • Another advantage of the invention results in the care of children.
  • these devices are often secured by protective covers, so that the controls can not be operated by the children.
  • the corresponding protective cover To operate a control element, the corresponding protective cover must first be removed in this case. In such devices, it is thus particularly advantageous if the last selected settings are valid again after switching off and on again.
  • the values of the parameters which can be set by a hearing aid wearer are advantageously stored in a nonvolatile memory which retains the stored values even when the power supply is interrupted, for example when the hearing aid is switched off.
  • the memory is designed as an EEPROM.
  • the current values of the parameters can either be immediately after each Change to be stored in the memory.
  • the hearing aid device can also first be transferred to a switch-off mode in which the current values are written to the relevant memory before the voltage supply is interrupted.
  • the invention provides that programming of the relevant hearing aid device determines for which of the parameters adjustable by the hearing aid wearer the values set before the switch-off should be valid again after switching on again and for which parameters after switching on again a standard setting is selected. For example, it can be determined in a hearing aid according to the invention that this is always always operated after switching in the hearing program with the program number 1, but with the volume setting is automatically set before switching off the current value.
  • values of parameters set during the switched-off state are not only retained by the user, but also values of parameters which are set automatically by the hearing aid device during operation.
  • the settings made automatically by the hearing aid device are usually based on the result of a signal analysis. Such settings relate in particular to the currently set hearing program, currently used algorithms or functions (noise suppression, directional microphone) or the automatic gain control.
  • the figure shows a hearing aid according to the invention in the block diagram.
  • a microphone 1 For receiving an acoustic input signal and conversion of the acoustic input signal into an electrical input signal, a microphone 1 is present.
  • the electrical input signal is for further processing and frequency-dependent amplification of a Signal processing unit 2 supplied.
  • the further processed and amplified signal is finally converted by a receiver 3 into an acoustic signal and fed to the hearing of a hearing aid wearer.
  • a battery 5 is present, which is connected via an on-off switch 6 with the different electronic hearing aid components.
  • the hearing aid according to the embodiment also has an interface 11 to a PC 12, via which the hearing aid can be programmed.
  • the parameters which can be set by the user or automatically by the hearing aid device can also be used to determine whether a value valid before switching off is also valid immediately after switching on, or whether a standard value should be set for this purpose.
