Abstract
Abstract The remote control of an operational parameter, such as the amplification factor (A) of the amplifier (19), of a hearing aid (1) occurs via acoustic waves (11) transmitted by a transmitter (10) of a remote control unit (2) and received by a pick-up (15) of the hearing aid (1). The acoustic waves can be ultrasonic waves or modulated waves.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
198 words
A combination of a hearing aid, being adapted to be supported upon the head of a user of the aid, and a remote control unit, the remote control unit comprising, control means, that can manually be operated by the user, an encoder unit having an input coupled to the control means and an output, and a transmitter having an input coupled to the output of the encoder unit, the encoder unit being adapted to convert control operations carried out by the user on the control means into a first control signal and to apply this first control signal via its output to the transmitter, for the wireless transmission of the first control signal, the hearing aid comprising a pick-up for receiving the first control signal transmitted by the transmitter of the remote control unit, a decoder unit having an input coupled to the pick-up for receiving the first control signal and an output, the decoder unit being adapted to convert the first control signal into a second control signal for controlling at least one operational parameter of the hearing aid, characterized in that the wireless transmission of the first control signal takes place by means of acoustic waves.
Claim 2
Dependent Claim
198 words
A combination of a hearing aid, being adapted to be supported upon the head of a user of the aid, and a remote control unit, the remote control unit comprising, control means, that can manually be operated by the user, an encoder unit having an input coupled to the control means and an output, and a transmitter having an input coupled to the output of the encoder unit, the encoder unit being adapted to convert control operations carried out by the user on the control means into a first control signal and to apply this first control signal via its output to the transmitter, for the wireless transmission of the first control signal, the hearing aid comprising a pick-up for receiving the first control signal transmitted by the transmitter of the remote control unit, a decoder unit having an input coupled to the pick-up for receiving the first control signal and an output, the decoder unit being adapted to convert the first control signal into a second control signal for controlling at least one operational parameter of the hearing aid, characterized in that the wireless transmission of the first control signal takes place by means of acoustic waves.
Claim 3
Dependent Claim
25 words
A combination as claimed in Claim 1, characterized in that the wireless transmission of the first control signal takes place by means of ultrasonic waves.
Claim 4
Dependent Claim
28 words
A combination as claimed in Claim 1 or 2, characterized in that the wireless transmission of the first control signal takes place by means of modulated acoustic waves.
Claim 5
Dependent Claim
73 words
A combination as claimed in Claim 1, 2 or 3, the hearing aid comprising a series arrangement of a microphone, an amplifier and a receiver, characterized in that the microphone also functions as the pick-up for receiving the first control signal, filter means being provided for deriving the first control signal from the output signal of the microphone, an output of the filter means being coupled to the input of the decoder unit.
Claim 6
Dependent Claim
29 words
A combination as claimed in Claim 4, characterized in that the first control signal lies in a frequency range which is outside the operating frequency range of the receiver.
Claim 7
Dependent Claim
48 words
A combination as claimed in Claim 3, or any one of the Claims 4 or 5, as far as appended to Claim 3, characterized in that the encoder unit in the remote control unit comprises a modulator and the decoder unit in the hearing aid comprises a demodulator.
Claim 8
Dependent Claim
38 words
A remote control unit for use in a combination as claimed in any of the preceding claims, characterized in that the transmitter is in the form of a transducer for the conversion of electric signals into acoustic signals.
Claim 9
Dependent Claim
40 words
A hearing aid for use in a combination as claimed in any one of the Claims 1 to 6, characterized in that the pick-up is in the form of a transducer for the conversion of acoustic signals into electric signals.
