  • a hearing aid is usually used to treat a hearing impairment.
  • At least one electro-acoustic input transducer of the hearing aid for example a microphone, converts a sound signal from the environment into an electrical audio signal, which is processed as a function of the hearing impairment and, in particular, is amplified as a function of the frequency band.
