1. A method for operating a hearing device having two acceleration sensors each providing a sensor signal being used to determine an orientation of a head of a user, which comprises the steps of:
- carrying out a calibration measurement for compensating for a skew position, with a long-term mean of a respective sensor signal being established in the calibration measurement;
using sensor signals of both of the acceleration sensors in combination for establishing the orientation;
combining the two sensor signals to form an overall signal, by means of the overall signal the orientation of the head is established, the two sensor signals each having a gravitational acceleration component and are combined to form the overall signal in such a way that gravitational acceleration components are eliminated and the overall signal is independent of gravitational acceleration; and
setting an operating parameter of the hearing device in dependence on the orientation.

Abstract
A method operates a hearing device. The hearing device contains two acceleration sensors, which each provide a sensor signal and by which an orientation of the head of the user is established. The sensor signals of both acceleration sensors are used in combination for establishing the orientation, and an operating parameter of the hearing device is set depending on the orientation.
