The present invention relies on the need for characterizing the response of the auditory, notably for diagnostic purpose and adjusting of the hearing apparatuses. For this, the inventors have found a new marker, which is the peak-to-plateau ratio of the peri-stimulus time response. The access to this value is easier to obtain than previously known markers. In particular, such value may be obtained in a non-invasive way opening the path to a non-invasive marker of ear disorder.
