The application relates to a hearing assistance device and to a method of performing a real ear measurement. The method comprises providing a first controlled acoustic feedback path from an output transducer to a measurement input transducer via a standard acoustic coupler; generating a first probe signal; estimating and storing a first estimate of the first controlled acoustic feedback path; and providing a second controlled acoustic feedback path from the output transducer to the measurement input transducer via the residual volume between the ITE part of the hearing aid device and the user's eardrum; generating a second probe signal; estimating and storing a second estimate of the second controlled acoustic feedback path; and determining a real ear to coupler difference from said first and second acoustic feedback estimates. An alternative and relatively simple method of determining an RECD-value in hearing assistance device of a particular user is thereby provided.

Method of performing an RECD measurement using a hearing assistance device

The present invention relates to a hearing aid logging data and learning from these data. The hearing aid () comprises an input unit () converting an acoustic environment to an electric signal; an output unit () converting an processed electric signal to a sound pressure; a signal processing unit () interconnecting the input and output unit, and generating the processed electric signal from the electric signal according to a setting; a user interface () converting user interaction to a control signal thereby controlling the setting; and finally a memory unit () comprising a control section storing a set of control parameters associated with the acoustic environment, and a data logger section receiving data from the input unit (), the signal processing unit (), and the user interface (); and wherein said signal processing unit () configures the setting according to the set of control parameters and comprises a learning controller adapted to adjust the set of control parameters according to the data in the data logging section.
