Hearing device with a means for receiver current estimation and a method of estimating a receiver current for a hearing device
Abstract:
A hearing device with a unit for estimating the current consumed by the receiver of the hearing device. The hearing device includes a signal input unit for converting an input signal picked up by the signal input unit into a digital audio signal, a signal processing unit for processing the digital audio signal, a digital-to-analog converter for converting a processed audio signal from the signal processing unit, a power amplifier for amplifying a converted audio signal from the digital-to-analog converter, a receiver for generating sound according to an amplified audio signal from the power amplifier, and a battery for powering the hearing device. A receiver current estimation unit has a filter for filtering a receiver current indicative signal derived from the processed audio signal, the filter having a frequency response dependent on an impedance of the receiver. A method is provided for estimating a receiver current for a hearing device.
