For the recording of parameters of the ear, especially the impedance of the ear canal with a hearing aid introduced into the ear canal, the sonic pressure is measured directly by a first pressure microphone and by a second pressure microphone by inserting of a calibrated acoustic resistance and by an evaluation electronics the impedance 2a is being calculated. By means of this value a periodical and accustical customization of the hearing aid, especially in- the-ear-hearing-aid, can advantageously be ensured.
