Abstract: A behind-the-ear hearing device has a hearing device housing and a user-operable switch. At least two microphones are disposed below the switch in the hearing device housing, and the housing is formed with first sound openings that are arranged directly below the switch. The switch is preferably a rocker switch. The microphones can be positioned below a switch in a space-saving fashion and the installation space of the hearing device housing can thus be used optimally.

Abstract: The data records to be stored in the two hearing devices of a binaural hearing system during the adjustment are generally different. With “side definition”, the correct assignment of the two hearing devices to the ears or of the wearer is ensured. To this end, an acoustic signal is transmitted to the wearer by way of the receiver of at least one of these hearing devices. The wearer informs the adjusting facility by way of an input device connected hereto, as to the ear with which the wearer heard this acoustic signal or which spatial characteristic or asymmetry is attributed to this acoustic signal.

Abstract: A hearing device that is operated with a rechargeable battery pack has at least one contact element that is fashioned to accept a charging current in electrical connection with an external charging device. The contact element is resiliently mounted at the hearing device and can be pressed onto a charging contact of the external charging device during a charging state under the application of a positive force. The contact element is located in a first position in an operating state or rest state of the hearing device, and is moved into a second position in the charging state.

Abstract: In a hearing aid device with a directional microphone system it is always to be possible to set the highest possible level of both directional effect and also amplification. To this end it is proposed that the directional effect be set as a function of the amplification set at the time. In particular a maximum directional effect that cannot be exceeded is defined depending on the amplification and stored in the hearing aid device. This makes it possible for the user to always have the greatest possible degree of directional effect with his hearing aid device.

Abstract: The data sets to be stored in the two hearing devices of a binaural hearing system during the adjustment are generally different. During “side definition”, the correct assignment of the two hearing devices to the ears and of the wearer is ensured. To this end, the wearer generates a signal on one of the two hearing devices, which is identified by the adjustment device and is evaluated for side definition purposes.

Abstract: A method for operating a digital, programmable hearing aid is provided that uses both a transmission characteristic of a normal amplification as well as a transmission characteristic of a maximum amplification of an audio signal over a frequency range that can be nearly freely configured. Given a modification of the amplification by settings at the hearing aid as well as using parameters that result from the signal processing, the gain for the overall system is always calculated utilizing all parameters and is potentially limited to the maximum amplification at the respective frequency if this would otherwise be exceeded.

Abstract: In order to improve the feedback compensation in hearing d vices th xtent of compensation is controlled. An estimated signal is acquired with which the intensity of the feedback signal is estimated. The damping of the feedback signal is thus controlled using the estimated signal. With this, it is, among other things, possible to disconnect the feedback compensation given no present feedback such that artifacts can be prevented.

Abstract: A self-powered medical device, which is operated independently of the public utility network, has at least one voltage source, a signal input for accepting an analog input signal and a signal processing unit. The sampling rate for the input signal or the clock frequency of at least one digital component can be varied. Therefore, the energy demand can be reduced according to the requirements of the signal processing or when the discharge state of the voltage source requires a reduction.
