METHOD OF DETECTING A DEFECT IN A HEARING INSTRUMENT, AND HEARING INSTRUMENT
First Claim
1. A method of detecting a defect in a hearing instrument having a first input transducer and an output transducer, the method comprising:
- determining a first transfer function of a first acoustic system including the output transducer and the first input transducer;
determining at least a first reference function for the first transfer function;
comparing the first transfer function with the first reference function; and
detecting a defect in the hearing instrument based on a result of the comparing step.

Abstract
A method for detecting a defect in a hearing instrument that has at least one first input transducer and at least one output transducer. A first transfer function of a first acoustic system, which includes the output transducer and the first input transducer, is determined, and at least a first reference function for the first transfer function is determined. The first transfer function is compared with the first reference function and a defect in the hearing instrument is detected based on the comparison. A hearing instrument with an input transducer and an output transducer is set up to carry out the method.
