Definitions
- the present invention relates to a hearing aid with an acoustic pickup to record a trouble-free or disturbed Acoustic signal and a control device for controlling of hearing aid parameters.
- the present concerns Invention a method for controlling a hearing aid.
- Hearing aids are used in various types of hearing situations and must provide the patient with the desired acoustic Communicate stimuli.
- the patient wants to Road traffic to perceive an omnidirectional Sound perception and when talking to a conversation partner experience a directed sound perception.
- the hearing aid wearer should use both corded as well as with cordless phones and with cell phones low-interference calls can be possible.
- Hearing aids are usually capable of different To cope with hearing situations by being from the hearing aid wearer switched to different hearing programs can be.
- a typical hearing program is the telephone hearing program, where the acoustic signals coming from the microphone of the hearing aid, according to the spectrum of telephone signals be filtered to remove distracting ambient noise suppress in other spectral ranges.
- High quality Hearing aids usually have multiple microphones, through a special hearing program to achieve a Directivity can be interconnected.
- Hearing aids are usually switched or controlled using switches, buttons or controls on the hearing aid housing.
- BTE behind-the-ear hearing aids
- ITE in-the-ear hearing aids
- CIC devices complete in the channel
- a hearing aid can automatically be included in a telephone hearing program be switched on or an auditory coil activated, if a magnetic field is detected by the handset of a telephone device is emitted.
- a magnetic field for example the conductivity, change
- Switching element for example, a displaceable magnet can be used.
- the actual contact elements fall under the category non-contact switches and can e.g. B. as so-called Thermowell contacts, also called reed contacts are known or as magnetic field semiconductors, which also Hall generators are designed to be.
- Thermowell contacts also called reed contacts are known or as magnetic field semiconductors, which also Hall generators are designed to be.
- the object of the present invention is therefore the automatic switching and control of hearing aids with regard to improve on the respective listening situation.
- this object is achieved by a hearing aid with an acoustic transducer to record a trouble-free or disturbed acoustic signal and a control device for Control of hearing aid parameters and an analysis device for analyzing the acoustic signal for interference signals and Delivering an analysis result to the control device, so that the hearing aid, in particular individual transmission parameters or entire hearing programs, based on the analysis result is controllable.
- the stated task is solved by a Method for controlling a hearing aid by picking up a interference-free or disturbed acoustic signal, analyzing the Acoustic signal after interference signals and control of the hearing aid, in particular individual transmission parameters or entire hearing programs, based on the analyzed interference signals.
- the useful signal namely the acoustic signal, that carries the acoustic information
- Sensor to be detected signal e.g. B. one magnetic DC signal
- a digital hearing aid 1 comprises according to FIG. 1 two microphones 2, 3 and optionally an audio coil 4.
- the two Microphones 2, 3 record the corresponding sound and convert it for further processing for the control device 5.
- the hearing coil or the induction pickup 4 the radiated by an induction system or a telephone coil Signal inductively recorded and for further processing also forwarded to the control device 5.
- the Control device 5 analyzes the sensors 2, 3 and 4 received signals and controls the transmission function between transducers 2, 3, 4 and one Speaker 6.
- the hearing aid is now switched or controlled or its hearing programs and / or transmission parameters not a signal from a switch or a constant signal an external device such as B. the static magnetic field signal a telephone handset coil.
- an external interference signal used for switching or controlling.
- the acoustic Interference signal superimposed on the useful signal can, for example be a broadcast signal from a mobile phone that despite shielding measures can be heard in the audio area.
- FIG. 2 There the time-division multiplex frame structure of data packets is described, as usually used in mobile radio technology becomes.
- the frameworks are subdivided hierarchically starting from hyperframes into subordinate superframes, Multiple frames and TDM frames.
- the frame length is of multiple frames in the traffic channel typically 120 ms, in the organization channel 235.4 ms and that of a TDM frame 4.615 ms.
- the corresponding transmission frequencies for TDM frames are in the audible range at around 200 Hz. Even higher ones Harmonics of the transmission frequencies of the multiple frames are in the audible range.
- Wireless telephone systems use certain defined frequency bands, in which they transmit their data packets.
- the Telephone standard DECT for cordless phones includes, for example Transmission frequencies between 1880 and 1900 MHz.
- the Sending a data packet takes approx. In the DECT telephone standard 417 ⁇ s.
- the individual data packets are grouped sent in 10 ms intervals.
- the digital D network for mobile phones based on the GSM standard based works in the range of 900 MHz with 992 channels, where 124 frequencies with 8 channels each in time multiplex be used.
- the channel grid is 200 KHz.
- the GSM-like DCS1800 standard based e-cellular network predefined frequency bands in the range of 1800 MHz.
- the American analog AMPS system with 666 channels and 30 KHz channel grid operated in the 800 MHz range.
- the interference interspersed in the hearing aid is now used to determine if the patient is using a cell phone phone.
- the distance between the mobile phone and the hearing aid may decrease can be clearly determined by threshold analysis whether there is an active telephone system near the hearing aid.
- disturbances, caused by wireless phone systems are in many frequency ranges.
- the high carrier frequencies of the transmission signals or the relatively low-frequency, characteristic signal patterns, with which the data packets are transmitted become.
- the immediate evidence of a bedding in, from a mobile phone originating carrier signal can be narrowband Signal detection is done. With a level meter, the in the hearing aid interspersed carrier signals in the typical Spectral range can be recognized.
- the electromagnetic interference is included the transmission rate of the data packets modulated. These modulations can be recognized in the signal processing of the hearing aids and are often perceived as disturbances in the audio area. Narrow band filtering for interference signals with packet frequency would, for example, provide a clear reference to the present Enter DECT fields on the hearing aid if their intensity is one Limit exceeded. Once the intensity of these interference fields drops again, it can be assumed that the Radiotelephone removed from the hearing aid or the phone call has ended.
- FIG. 3 shows a typical signal curve f (t) of a Interference signal, such as that caused by a time slot-oriented radio telephone system is caused.
- the increases in amplitude are clear can be seen in time slots 0 and 80.
- the function curve g (t) shows that for evaluation in FIG. 3 below processed audio signal.
- the hearing aid can use the characteristic interference signals are switched or controlled.
- characteristic interference signals individual hearing aid parameters can be changed automatically. For example, the hearing aid be switched to a predetermined gain if telephoning the hearing aid wearer with a mobile phone is recognized. Likewise, the filter bandwidth of the hearing aid be reduced when the hearing aid is making a call with a Cordless phone registered.
- hearing programs are changed at the same time by a hearing program switched to another.
- the hearing aid if it detects the proximity of a telephone device, from a hearing program for directed hearing into a hearing program can be switched for omnidirectional listening.
- interference signals to control and switch Hearing aids is not just in the area of walkie talkies limited. Rather, it is also possible for the hearing aid when detecting interference signals caused by digital television, Music transmission caused by headphones and the like switch to a suitable hearing program.
