摘要： An apparatus for determining cochlear dead region comprising a sound generation unit, an output transducer, and a control unit. The control unit causes the sound generation unit to provide a first electrical sound signal representing a first frequency band adjacent to a frequency region of interest, with a first bandwidth, a first sound pressure level and a first subsequent electrical sound signal representing a first subsequent frequency band comprising the frequency region of interest with a first subsequent bandwidth, a first subsequent sound pressure level, and a first subsequent time delay to the first electrical sound signal. In response, the output transducer generates a first output sound and a first subsequent output sound with the first subsequent time delay. A user compares the first output and first subsequent output sounds and decides, whether he hears a difference between the two sounds and gives a positive or negative decision input.

The flexible sealing part comprises a core hole permeable for sound transmitted from the air filled tube through a core pathway. The air filled tube is further configured to be arranged in a user's ear canal to transmit sound generated by the BTE unit to a tympanic membrane of the user. The flexible sealing part is arranged in a bony portion of the user's ear canal when in use. The diameter of the flexible sealing part is at least as large as the diameter of the bony portion of the ear canal of a user to close the ear canal.
