1. A hearing aid comprising a first sensor for sensing a first parameter indicative of a use situation of the hearing aid, the hearing aid defining a direction parallel to the vertical direction when in a use situation,wherein the hearing aid is configured to change into a high power mode or a low power mode in response to a first control signal from the first sensor,wherein the first sensor is a three-axis accelerometer having one axis aligned with the defined direction, and wherein the hearing aid changes from the high power mode to the low power mode by:

  • measuring accelerations of the hearing aid in three directions from the first sensor;

    determining whether an orientation of the hearing aid deviates more than a threshold value from vertical;

    determining whether a total acceleration of the hearing aid deviates less than a predetermined value from earth'"'"'s gravity; and

    changing the hearing aid from the high power mode to the low power mode when the orientation deviates more than the threshold value from vertical and the total acceleration deviates less than the predetermined value from earth'"'"'s gravity in response to the first control signal from the first sensor.
