Abstract: A method of operating a hearing system for conducting telephone calls as well as a hearing system capable of performing the proposed method. The hearing system includes a communication device (4) with a communication device microphone (3?) for picking up a first sound signal and providing a primary sidetone signal. The hearing system further includes a hearing device with a hearing device microphone for picking up a second sound signal and providing a secondary sidetone signal. A first amplification is applied to the primary sidetone signal and a second amplification is applied to the secondary sidetone signal. Adjusting of the first amplification is dependent on adjusting of the second amplification, or alternatively, adjusting of the second amplification is dependent on adjusting of the first amplification. The primary and secondary sidetone signals are then combined and subsequently output by a hearing device loudspeaker.

Abstract: A method for controlling and/or configuring a user-specific hearing system using a computing and/or communication device. The hearing system includes at least one hearing device customisable according to the individual hearing ability and/or preferences of a user of the hearing system. The method includes connecting the hearing system to a server via a network, connecting the computing and/or communication device to the server via the network, providing by the server a hearing system control and/or configuration service tailored to the user-specific hearing system to the computing and/or communication device, determining and/or selecting at the computing and/or communication device control data and/or configuration data using the hearing system control and/or configuration service, sending the control and/or configuration data from the computing and/or communication device to the hearing system, and adjusting the hearing system based on control and/or configuration data received at the hearing system.
