Rond de 2000 Hz is dit geleidingsverlies minder groot en lijkt het verlies perceptief te zijn, niet veroorzaakt door disfunctioneren van het slakkenhuis, maar door een gestoorde overbrenging, de zogenoemde Carhart notch. Dit ogenschijnlijk perceptieve verlies zal verdwijnen na operatief ingrijpen. Voorkomen

Objective: To evaluate the ability of the Carhart notch to predict the presence of effusion at the time of myringotomy and to evaluate its incidence in otitis media with effusion. Method: A prospective study that comprised 75 children who were admitted to King Fahd Hospital of the University (KFHU), Al Khobar, Saudi Arabia for myringotomy and possible ventilation tube insertion as treatment 2021-02-24 Audiologist Raymond T. Carhart in 1950 was first to show in these patients a 10–20 dB BC hearing loss in the narrow 1–2 kHz range of input frequencies, with no significant hearing loss at lower and higher frequencies, which has since been named ‘Carhart’s notch’ (CN).

An audiological feature of 2KBD, Carhart notch, is widely known and is traditionally believed to suggest stapes fixation 10; however, few investigations have verified its usefulness. In the present study, we evaluated the significance of Carhart notch in predicting stapes fixation and found that 2KBD was ineffective as a predictive tool.

Introduction: Carhart's notch (CN) is a false depression of bone conduction (BC) thresholds at 2–4 kHz initially described in cases of stapes fixation. This study was designed to estimate the incidence and assess the clinical significance of CN in cases of otitis media with effusion (OME) in children.

The Carhart notch is a depression in the bone-conduction audiogram of patients with clinical otosclerosis. The middle frequencies from 0.5 to 2 kHz, which correspond to the resonance frequency of the middle ear, can be substantially improved following successful stapes surgery.

The Carhart notch is an elevation in the middle-frequency bone-conduction threshold of an ear with clinical otosclerosis. The study population consisted of 138 patients with clinical otosclerosis. Conventional air-conduction (AC) and bone-conduction (BC) and electric bone-conduction (EBC, with Audimax 500 audiometer) thresholds were measured 2 weeks before and 7 months after stapes surgery. The Carhart notch is a depression in the bone-conduction audiogram of patients with clinical otosclerosis.
