Definitions
- the present invention relates to a hearing aid with a Radio device for signal transmission, in particular to a second hearing aid, wherein the radio device comprises an antenna device for sending and / or receiving. Further concerns The present invention relates to a hearing aid in which measures are taken for noise reduction and a corresponding method for noise reduction in hearing aid reception signals of the wireless transmission system.
- hearing aid technology is the bidirectional, wireless Coupling of the hearing aids with binaural supply, d. H. the Supply each ear with one hearing aid each, one for many audiologists aspire to goal. Due to the spatial and the energetic restrictions, however, is the use the previously known, wireless transmission systems impossible under real conditions. In particular, the realization the function of sending out of the hearing aid is out with reasonable energy consumption so far not feasible been.
- hearing aids are known which via a binaural coupling based on a wireless transmission link but with unidirectional FM transmission systems with audio bandwidth (CROS / BiCROS systems) and high energy consumption can be used.
- CROS / BiCROS systems unidirectional FM transmission systems with audio bandwidth
- the object of the present invention is therefore to a wireless coupling of hearing aids with improved energy consumption to provide.
- this object is achieved by a hearing aid with a radio device for signal transmission in particular to a second hearing aid, wherein the radio device comprises an antenna device for sending and / or receiving, and wherein the antenna device is a self-excited oscillating circuit includes.
- the invention provides a hearing aid with a Receiving device for receiving a plurality of values at least a radio signal, the receiving device being a median filter device having a mean value of several values for Störsignalverminderung can be determined.
- the invention is based on the idea of a transmission path over the low rate control data can be transmitted. Preferably, this can be done by a Half-duplex transmission line can be realized. For reasons the effectiveness should be for the transmission of the long wave range be used. This is preferably possible economically by an inductive coupling with the respective realize other hearing aid.
- the use of a quartz oscillator for a frequency reference for data transmission from spatial Reasons not possible. Therefore, conveniently, the following described antenna oscillator transmitter side as a frequency standard used for the transmission system. Next the determination of the transmission carrier frequency over the resonance frequency of the antenna oscillator can for the transmitted Data stream a bit clock (bit clock) by dividing down derived from the carrier frequency.
- bit clock bit clock
- the transmitting antenna is an LC oscillator consisting of a coil and a capacity used, the about a high quality, z. B. Q> 10.
- This LC oscillator ensures high efficiency. He can, for example be stimulated in the transmission case with low power and then swings open. The case in the resonant circuit resulting high reactive currents ensure good radiation the coil (leakage inductance). For data transfer can this self-excited resonant circuit in its resonant frequency detuned and thus used for frequency modulation.
- the LC resonant circuit for both the generation a carrier frequency for transmission as well as for clocking the receiving device, in particular a contained therein Filter device to be used.
- the data rate is determined by the carrier frequency and a predetermined divider.
- the Radio device of the hearing aid from a Transmitter circuit 1, an antenna circuit 2 and a receiver circuit 3.
- a data processing unit 4 is connected to the receiver circuit 3 connected.
- the transmitter circuit 1 comprises an amplifier 11, which via a switch S1 to the Antenna circuit 2 is connected.
- the antenna circuit 2 which consists of a parallel circuit a coil L1 and a capacitor C1, by appropriate feedback with the amplifier 11 excited with resonant frequency.
- Parallel to the amplifier 11 is a series circuit of a capacitor C2 and a switch S2 connected. If the capacitor C2 is connected to the capacitor C1 , the resonance capacity increases, increasing the resonant frequency sinks. Thus, with the help of the switch S2 the Resonant frequency can be varied.
- the coil L1 in the antenna resonant circuit 2 allows a good Radiation in the long wave range. If now the switch S2 is switched to the clock of the data to be transmitted is from the coil L1 is a corresponding frequency-modulated data signal radiated wirelessly.
- the LC antenna circuit 2 can in one realized a compact resonant circuit very small space become.
- the resonant circuit 2 is also relatively low-energy to operate, since he only through the amplifier 11 needs to be triggered shortly. It just has to be that one Energy is supplied by the radiation of the coil L1 is lost.
- the receiver circuit 3 is also connected to the antenna circuit 2 connected. Does the antenna circuit 2 as a receiver, so the signal in the receiver circuit 3 is first in a Preamplifier 31 and then a bandpass filter 32 supplied. Freed from inconsiderable frequency components the signal is further amplified in an amplifier 33, optionally further processed and a median filter 34 supplied. This median filter 34 filters out, for example five values out the middle and takes care of that for a very good suppression or reduction of disorders. The output of the median filter 34 is with a Evaluation unit 35 connected. From the output of the evaluation unit 35, the received signal leaves the receiver circuit 3 and is sent to a further processing device 4, for example used for transmission control or an interface represents, transmit.
- a further processing device for example used for transmission control or an interface represents, transmit.
- Antenna Oscillator 2 is not only the resonant frequency of the antenna oscillator as a carrier frequency but also transmitted a corresponding Bittakt.
- the high impedance to the antenna circuit 2 connected receiving part. 3 is constantly active and directs besides the bittakt also the means Frequency modulation transmitted information from the received signal from.
- the receiving part or the receiver circuit 3 is thus capable of being inductively transmitted from the low energy Signal with suitable reduction of noise components a narrowband information transmission for hearing aids to ensure.
