A hearing device having an input unit for converting an acoustic input to a first signal, an output unit for converting a second signal to an acoustic output and a signal processing unit for generating said second signal from said first signal based on a setting indicating a characteristic of a user's ear, said signal processing unit coupling said input unit and said output unit, to a corresponding method for providing a hearing aid and a corresponding computer program. In order to provide an adaptive hearing device and a method for providing a hearing aid which allow for a compensation for the change in a characteristic of a user's ear, in particular for the change to the ear of a child during growth and which are of a low complexity and do not need additional sensors.

Adaptive hearing device and method for providing a hearing aid

The invention relates to a fitting equipment for fitting a hearing aid, the equipment comprising a computer having a display, where the computer is provided with a fitting software adapted for controlling parameters of the hearing aid upon control of indicators in the software, where the indicators are visible on the display, where a default fitting rationale may be chosen and where in the fitting software at least two variant settings which are offset in relation to the default setting are provided and may be activated from the software by means of the computer, where in the first variant setting the release time in both the LF and HF channels are lengthened and the amount of gain for soft inputs is reduced in both the LF and HF channels and where in the second variant setting the release time in the HF is shortened and the soft gain is increased in both the LF and HF channels.

Hearing aid fitting

The invention relates to a method for reducing feedback caused by electromagnetic interference between an induction coil and an output transducer, a voltage supply or an amplifier or a combination thereof, the method comprising: producing by means of a filter an equivalent of an electromagnetic feedback path in a system with a pickup coil and subtraction of the equivalent of the feedback signal from the input signal in order to obtain feedback reduction. The invention further relates to a device for implementing the method, the device comprising an induction coil and an output transducer, voltage supply or an amplifier or a combination thereof. The device further comprises filter means for generating an equivalent of an electromagnetic feedgack signal occurring between the induction coil and an output transducer, a voltage supply or an amplifier or a combination thereof and means for subtracting the equivalent from an input signal in order to obtain feedback reduction.
