The disclosure presents a method and an amplifier system for minimizing variation in an acoustical signal caused by variation in gain of an amplifier, comprising a battery for providing a supply voltage to the amplifier, a digital signal processor for providing the acoustical signal to the amplifier, a controller unit receiving an enablement signal when the supply voltage is in an offset mode, and based on the enablement signal requesting a measured voltage during a time period, and a first analog-to-digital converter configured for measuring the supply voltage to the amplifier when receiving the request from the controller unit or the first analog-to-digital converter is configured for measuring the supply voltage to the amplifier continuously, and where variations in the measured voltage relates to variations in the supply voltage during the time period. Furthermore, the controller unit is configured to predict offset modes (i.e. changes) in the supply voltage based on the enablement signals and a fitting of the measured voltages, and wherein the controller unit is configured to generate a compensating signal based on the fitting and transmit the compensating signal to the digital signal processor, the digital signal processor is then configured to minimize variation in the acoustical signal at the output of the amplifier by compensating the variation in gain of the amplifier based on the compensating signal.

Hearing device comprising an amplifier system for minimizing variation in an acoustical signal caused by variation in gain of an amplifier

A hearing aid device for processing signals comprising audio in order to assist a hearing impaired user and being configured to be arranged at, behind and/or in an ear of the user is disclosed. The hearing aid device comprises at least one input transducer, an output transducer, an antenna, a wireless interface, and a signal processing unit. The at least one input transducer is adapted for receiving signals comprising audio. The output transducer is adapted for providing signals comprising audio to the user. The antenna is adapted for wirelessly communicating with a respective external device. The wireless interface is adapted for receiving and/or sending data via the antenna. The signal processing unit is adapted for processing signals comprising audio in order to assist a hearing impaired user. Furthermore the signal processing unit is adapted for extracting speech signals from the signals comprising audio and for generating control signals based on the speech signals. At least one of the control signals generated by the signal processing unit is adapted for controlling the respective external device. The wireless interface is adapted for sending the at least one of the control signals to the respective external device via the antenna in order to control the respective external device.

Hearing aid device with speech control functionality

A hearing aid device configured to be partly or fully inserted into the ear canal of a user is disclosed. The hearing aid device comprises a receiver (loudspeaker) adapted to generate and send an air-borne acoustic signal towards the eardrum when the hearing aid device is partly or fully inserted into the ear canal. The hearing aid device further comprises a microphone configured to receive acoustic signals. The hearing aid device comprises a processing unit configured to determine if the hearing aid device is positioned in a correct position in the ear canal on the basis of the acoustic signals received by the microphone.
