title: [Frequency-dependent cochlear microphonics in inner ear hearing loss with various pitch thresholds].
abstract: Promontory recordings of the cochlear microphonics (CM) after stimulation with 0.5, 1 and 2 kHz tone bursts at 120 dB SPL were performed on normal subjects and patients with various, levels of sensory hearing loss. A significant correlation was found between frequency-related CM amplitudes and the configuration of the pure-tone audiogram. Such recordings provide objective information on hearing abilities at low and middle frequencies and are thus a relevant tool in clinical audiometry.
