Method for determining frequency dependent uncomfortable loudness level for adjusting hearing aid in test person, involves finding uncomfortable level as level, in which measured conductivity of skin exceeds threshold value at first time

摘要

The method involves providing a test signal to a test person. Conductivity of skin of the test person is detected, during provision of the test signal. The conductivity of the skin is measured via electrodes, which are attached at a bone vibrator. The conductivity is compared with a pre-determined threshold value. Uncomfortable loudness level is determined as a level, in which the measured conductivity of the skin exceeds the threshold value at the first time. The threshold value is larger than the conductivity value of the skin, in a resting condition of the test person. An independent claim is also included for an arrangement for determining the frequency dependent uncomfortable loudness level for adjusting the hearing aid in the test person.
