摘要

The hearing aid has an input converter for receiving an acoustic input signal and convert the input signal into an electrical input signal. A signal processing unit is provided for processing the input electrical signal, and for generating an electrical output signal. An output transducer is provided for converting the electrical output signal into an output signal perceptible as an acoustic output signal for a user. Electrical components are provided, which are free from ferromagnetic materials, where nickel-free capacitors are used.
