Abstract: According to the present invention, a three-line bus is used for communication between a first digital unit (1) and two other digital units (3). The three-line bus includes a system clock line (SCL) as well as a data transmission line (SD) through which data is sent from the two other units (3), i.e. transmitting units, to the first unit (1), i.e. receiving unit. The system uses an authorization line (WS) for determining which of the two transmitting units (3) is capable of writing data on the data transmission line (SD) and when it can do so. The communication from the first unit (1), now operating as a transmitter, to the two other units (3), now operating as receivers, is made possible by the fact that data signals are also injected in the authorization line (WS) and transmitted through the line together with the authorization control signals.

Abstract: The present invention relates to a method for recording information in a hearing device and/or in a recording unit at least temporally operationally connected to the hearing device. The method consists in that a point in time of the recording and/or a recording frequency as well as the information to be recorded, as data and/or parameters and/or adjustments of the hearing device are adjusted freely or are programmable, respectively. Furthermore, a hearing device is described that is suitable to use the method. By the present invention, a multitude of the parameters being adjustable in a hearing device can be checked or surveyed all together or selectively in real, i.e. actually existing acoustic environments in order to optimally adjust or adapt the hearing device afterwards, that means after the analysis by the fitter, for example.
