Definitions
- the present invention relates to a hearing aid having a self-test capability.
- the operator of the hearing aid may be the hearing impaired user of the hearing aid or an audiologist fitting, fine tuning or otherwise working with the hearing aid.
- a hearing aid having at least one input transducer for transforming an acoustic input signal into a first electrical signal, a signal processor for compensating a hearing deficiency by generation of a second electrical signal based on the first electrical signal, an output transducer for conversion of the second signal into sound, and at least one probe means for determination of a signal parameter at a first point in the signal path of the hearing aid.
- the hearing aid may comprise a test controller for detection of a defect in the signal path of the hearing aid.
- the test controller may be connected with and adapted to control at least one test signal generator, such as a tone generator, a noise generator, a digital word generator, etc, at least one probe means for determination of a signal parameter, such as signal level, frequency spectrum, phase characteristic, auto-correlation, cross-correlation, etc, and at least one signal switch provided in the hearing aid.
- the at least one signal switch is provided for connecting a desired test signal generator or a desired probe means to a desired point in the signal path for testing of a desired part of the hearing aid. Further signal switches may be provided for coupling hearing aid components into or out of the signal path of the hearing aid.
- the signal path is constituted by components and transmission paths of the hearing aid that receive and transmit signals that are derived from the first electrical signals of the hearing aid.
- test controller may be adapted to control respective signal switches to disconnect all of the at least one input transducers from the signal path of the hearing aid and to activate a probe means for determination of the signal level at a selected or predetermined point in the signal path whereby the noise level generated by input circuitry of the hearing aid may be determined.
- the value of a signal parameter as determined by the at least one probe means may be compared to a reference value that may be stored in a memory in the hearing aid. If the detected value lies outside a predetermined range comprising the reference value, it may be signalled to the operator of the hearing aid that the hearing aid comprises a defect.
- the type of defect may also be signalled. For example, a specific tone or a specific sequence of tones may be generated by the output transducer signalling that the hearing aid is defect to the hearing impaired user. A specific tone or a specific sequence of tones may correspond to a specific defect.
- the hearing aid is connected to a hearing aid programming device with a display, the fact that the hearing aid comprises a defect may be displayed on the display and, further, an indication of the type of defect may be displayed.
- the noise level is greater than a predetermined reference value, it may be signalled that the hearing aid comprises a defect.
- the processor is preferably divided into a plurality of channels so that individual frequency bands may be processed differently, e.g. amplified with different gains.
- the hearing aid according to the invention may further comprise a filter bank with bandpass filters for dividing the first electrical signal into a set of bandpass filtered first electrical signals, and wherein the processor is adapted to generate the second electrical signal by individual processing of each of the bandpass filtered first electrical signals and adding the processed electrical signals into the second electrical signal.
- the test controller may be adapted to selectively connect a desired test signal generator or a desired probe means to the output of a selected bandpass filter.
- a probe means for level detection may be connected to the output of a selected bandpass filter in order to determine the noise level in a selected frequency band.
- a test signal generator is provided that is controlled by the test controller for generation of a desired electronic signal that is transmitted to the output transducer of the hearing aid for conversion into a sound signal.
- the hearing aid is situated in a compartment with hard walls so that a large part of the generated acoustic signal is received by the at least one input transducer.
- the test controller is further adapted to control a signal switch to connect a selected probe means, such as a level detector, etc, to one of the at least one input transducers for determination of a signal parameter, such as the signal level, of the respective generated first electrical signal.
- the determined value of the signal parameter may be compared to a reference value that may be stored in a memory in the hearing aid, and if the detected value is less than the reference value, it may be signalled as previously described to the operator of the hearing aid that the hearing aid comprises a defect.
- the type of defect may also be signalled. For example, it may be displayed on the display of a programming device that the input port to the input transducer in question should be checked for ear wax.
- the input transducer connected to the signal path may be the pick-up coil.
- the pick-up coil in the hearing aid may be tested in a way similar to the one described previously for an acoustic input transducer, since the output transducer typically generates a significant magnetic field that is picked up by the pick-up coil.
- the probe means may be connected to the output of a selected bandpass filter to determine signal level of the generated first electrical signal in the corresponding frequency band.
- the probe means may be sequentially connected to the outputs of more or all of the bandpass filters to determine the signal parameter in question in more or all frequency bands. In this way the frequency spectrum of the generated first electrical signal may be determined, or harmonic distortion may be determined.
- the test controller may be adapted to connect a selected probe means for level detection to the output of a bandpass filter that comprises a third harmonic of the output of the test signal generator for determination of harmonic distortion.
- Signal switches may be provided for connecting a test signal generator, such as a tone generator to the input of the signal processor, and for connecting a probe means to the output of the signal processor whereby the gain of the signal processor may be determined. Further, the gain of the signal processor may be determined as a function of the frequency.
- the compression of the signal processor i.e. gain as a function of input level may be determined, e.g. as a function of frequency.
- an adaptive feedback loop comprising an adaptive filter in the hearing aid to compensate for acoustic feedback.
- Acoustic feedback occurs when the input transducer of a hearing aid receives and detects the acoustic output signal generated by the output transducer. Amplification of the detected signal may lead to generation of a stronger acoustic output signal and eventually the hearing aid may oscillate.
- the adaptive filter estimates the transfer function from output to input of the hearing aid including the acoustic propagation path from the output transducer to the input transducer.
- the input of the adaptive filter is connected to the output of the hearing aid and the output signal of the adaptive filter is subtracted from the input transducer signal to compensate for the acoustic feedback.
- a hearing aid of this type is disclosed in US 5,402,496.
- the test controller may be adapted to verify operation of the adaptive feedback loop, e.g. the test controller may control a signal switch to disconnect the feedback loop from the signal path and increase the gain of the signal processor until oscillation occurs.
- the hearing aid is situated in the compartment with hard walls during this test.
- the test controller may further be adapted to reconnect the adaptive feedback loop to the signal path whereby oscillation should seize if the adaptive feedback loop operates correctly.
- the hearing aid may comprise a test signal generator for injection of a digital signal at a selected second point in the digital part of the signal path of the hearing aid, e.g. at the input of the signal processor.
- a hearing aid without defects will generate a signal with certain parameter values at the selected first point in the signal path.
- the parameters may relate to frequency, amplitude, spectrum, modulation, phase, etc, and the parameter values of a hearing aid operating without defects are desired values.
- the test controller may further be adapted to compare the parameter values of the actual response signal with the desired values to determine whether the hearing aid comprises a defect. If an actual value lies outside a predetermined range comprising the respective desired value, it may be concluded that the hearing aid in question comprises a defect. The presence of a defect may be signalled to the operator of the hearing aid as previously described.
- the self-test may be initiated upon user activation of at least one switch positioned on the hearing aid housing, or on a hearing aid programming device, or on a remote control unit for the hearing aid, or on a fitting system, etc.
- Preferably two switches has to be activated simultaneously or sequentially to avoid accidental activation of the self-test.
- Fig. 1 shows a hearing aid 10 having two input microphones 12, 14 and a pick-up coil 16.
- a signal switch matrix 18 selectively connects any of the input transducers 12, 14, 16 to a desired A/D converter 20, 22.
- the output signal 24 from A/D converter 20 is split into a set of bandpass filtered signals 24 1 , 24 2 ,...,24 n by a set 26 of bandpass filters.
- the processor 28 is divided into a plurality of channels so that individual frequency bands may be processed differently, e.g. amplified with different gains.
- the processor 28 generates the second electrical signal 30 by individual processing of each of the bandpass filtered first electrical signals 24 1 , 24 2 ,...,24 n and adding the processed electrical signals into the second electrical signal 30.
- a D/A converter 32 converts the digital output signal 30 to an analogue signal 34.
- An output transducer 38 converts the analogue signal 34 into sound.
- circuits indicated in Fig. 1 may be realised using digital or analogue circuitry or any combination hereof.
- digital signal processing is employed and thus, the signal processor 28 and the filter bank 26 are digital signal processing circuits.
- all the digital circuitry of the hearing aid 10 may be provided on a single digital signal processing chip or, the circuitry may be distributed on a plurality of integrated circuit chips in any appropriate way.
- Signal switches 36 1 , 36 2 ,...,36 p are provided throughout the signal path of the hearing aid circuitry for connecting a test signal generator 40, e.g., a tone generator 40, or a probe means 42, e.g. a level detector 42, to the respective points in the signal path of the hearing aid 10.
- a test controller 44 controls the settings of the signal switches 36 1 , 36 2 ,...,36 p for detection of a defect in the signal path of the hearing aid 10.
- the control lines connecting the test controller 44 with each of the respective signal switches 36 1 , 36 2 ,...,36 p are not shown in Fig. 1.
- the test controller 44 further controls the signal switch matrix 18 for connecting microphones 12, 14 and pick-up coil 16 to and disconnecting them from the signal path of the hearing aid 10. Further, the test controller 44 is adapted to control the test signal generator 40, e.g. to generate an electrical signal of a selected frequency, e.g. 1 kHz, e.g. with a selected amplitude and/or frequency modulation, and to control the probe means 42 for determination of a selected signal parameter, such as the rms value. For example noise level in frequency band 2 may be determined by the test controller 44 controlling the signal switch matrix 18 to disconnect all of the input transducers 12, 14, 16 from the A/D converters 20, 22 and connecting the level detector 40 to the output 24 2 of a bandpass filter 26 2 .
- a selected signal parameter such as the rms value
- the test controller 44 may control the signal switch 36 1 to connect the test signal generator 40 to the input of the signal processing circuitry 26, 28 and simultaneously disconnecting the input from other signal sources, and the signal switch 36 4 to connect the probe means 42 to the output of the signal processor 28 facilitating test of any of the signal processing algorithms performed in the signal processing circuitry 26, 28.
- signal parameters of the output signal generated by the signal processor without any defects in response to the test signal may be stored in a memory (not shown) in the hearing aid 10, and the test controller 44 may compare the parameters of the actually generated output signal of the signal processor 28 with the corresponding stored parameters in order to determine whether the hearing aid 10 comprises a defect.
- a signal switch 36 3 for interrupting the signal 30 before the signal switch 36 2 and controlled by the test controller 44 is also provided. Having interrupted the signal 30, the test controller activates the tone generator 40 to generate a signal of a selected frequency, e.g. 1 kHz, that is transmitted to the output transducer 38 of the hearing aid 10 for conversion into a sound signal.
- the hearing aid 10 is situated in a compartment with hard walls so that a large part of the generated acoustic signal is received by the at least one input transducer 12, 14.
- the test controller 44 further controls signal switch 36 i to connect probe means 42 to one of the at least one input transducers 12, 14 for determination of the signal level of the respective generated first electrical signal in the respective frequency band i.
- the self-test is initiated upon reception of a signal 48 from the activation means 46.
- the activation means may be constituted by one or more switches positioned on the housing of the hearing aid 10 or the activation means may comprise interface means that is adapted to receive a command 49 for initiation of the self-test from an external device, such as a remote control unit, a hearing aid programming device 50, a fitting device, a personal computer, etc.
- the hearing aid 10 may be connected to a hearing aid programming device 50 with a display 52.
- the operator may initiate the self-test by pressing a specific key or set of keys 54 on the programming device 50.
- the device 50 displays that it is ready to perform a self-test as shown in Fig. 2.
- the self-test is performed upon activation of key 56.
- the programming device transmits a corresponding command to the activation means 46 of the hearing aid 10 and indicates that the self-test is in progress as shown in Fig. 3.
- the test described in the previous section may reveal that no second signal is generated by one of the microphones 12, 14.
- a probable cause may be that the input port to the microphone has been occluded by ear wax, thus the operator is asked to check if this is the problem in Fig. 4. If no problems have been revealed during the self-test, a corresponding message is displayed as shown in Fig. 5.
- the input transducer connected to the signal path may be the pick-up coil 16.
- the pick-up coil 16 in the hearing aid 10 may be tested like an acoustic input transducer 12, 14, since the output transducer 38 typically generates a significant magnetic field that is picked up by the pick-up coil 16.
- the test controller 44 controls the signal switch matrix 18 to disconnect all of the input transducers 12, 14, 16 from the signal path, and connects the test signal generator 40 to the signal path through signal switch 36 1 .
- the probe means 42 is connected to the output of the signal processor 28 through signal switch 36 4 .
- the gain of the signal processor 28 is determined as a function of the frequency.
- the compression of the signal processor 28, i.e. gain as a function of input level may be determined, e.g. as a function of frequency.
