As first described in 1950 by Raymond Carhart, the audiometric profile of classic otosclerosis presumes a "Carhart Notch" (CN) most likely to be found at 2000 Hz. Since that time, there have been multiple reports in the literature reporting CNs likely to be distributed between 500 and 2000 Hz.

Mar 27, 2021 The Carhart notch, an audiological finding mainly of historical importance, is a dip at 2000 hz in bone conduction without a corresponding dip in

2021-03-09 · Abstract. Otosclerosis is a disease process of the ear that stiffens the stapes annular ligament and results in footplate immobilization. This produces a characteristic loss in bone-conducted (BC) hearing of about 20 dB between 1 and 2 kHz, known as "Carhart's notch", for which the specific mechanisms responsible have not yet been well understood.
