Abstract

A portable hearing assistance device comprises an input unit, an output unit, a forward path between the input unit and the output unit, and an energy source for energizing components of the hearing assistance device. The hearing assistance device further comprises a control unit to control activation (or deactivation) of a low-power mode of operation of the hearing assistance device. When the low-power mode is activated—the draw of current from said energy source is reduced compared to a normal mode of operation of the device, the activation (or deactivation) being influenced by a combination of at least two different control input signals to the control unit, each control input signal being a signal selected from 1) signals relating to current physical environment, 2) signals relating to current acoustic environment, 3) signals relating to current wearer state, and 4) signals relating to current state or operation mode.
