Problems solved by technology

[0005] Both methods use additional measuring equipment and require additional time-consuming steps during hearing instrument fitting
In addition, they suffer from translation errors caused by measurement conditions not exactly corresponding to real wearing conditions

Embodiment Construction

[0098] The detailed description set forth below in connection with the accompanying drawings serves as a description of a number of different configurations. The detailed description includes specific details to provide a thorough understanding of various concepts. It will be apparent, however, to one skilled in the art that these concepts may be practiced without these specific details. Several aspects of the apparatus and methods are described in terms of a number of different blocks, functional units, modules, elements, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). Depending on the particular application, design constraints, or other reasons, these elements may be implemented using electronic hardware, computer programs or any combination thereof.

[0099] Electronic hardware may include microprocessors, microcontrollers, digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic devices (PLDs), gat...

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.

Description

technical field [0001] The present application relates to hearing devices and in particular to adapting a hearing device to a particular user, eg adapting the gain to provide a requested sound pressure at the user's ear. The present application also relates to the use of a hearing device, a method of operating a hearing device, and a combined system comprising a hearing device and a programming device. [0002] Embodiments of the present invention may be used, for example, in applications such as hearing aids, headphones, headsets, active ear protection systems, or combinations thereof. Background technique [0003] There are uncertainties regarding the sound pressure produced by the hearing instrument when the hearing instrument is at or in the user's ear. The uncertainty arises from individual ear characteristics that are not known a priori. Individual ears may vary in geometry, ear canal volume, and tympanic membrane properties. These factors affect the auditory perfor...
