Abstract
The application relates to a hearing device comprising an input unit for providing an electric input audio signal, a configurable signal processing unit for processing an audio signal and providing a processed audio signal, and a reversible output transducer for converting an electric output signal to an acoustic output sound. The hearing device further comprises a measurement unit configured to convert a sound pressure level to an electric signal, termed the measurement signal, and a control unit configured to determine a present electric impedance of the output transducer or a measure indicative of said present electric impedance from said measurement signal. This has the advantage that no additional microphone or other measurement equipment is needed to provide a (e.g. in-situ) real ear measurement of sound pressure level. The invention may e.g. be used to control audio signal processing in hearing aids, headsets, ear phones, active ear protection systems, or combinations thereof.
