title: [Amplitude and time characteristics of latent auditory evoked potentials in occupational hearing disorders with and without the recruitment phenomenon].
abstract: Cortical evoked potentials (CEP) of workers exposed to industrial noise were recorded by an Amplaid MK-6 unit (Italy). They suffered from neurosensory hypoacusis with or without the recruitment phenomenon. The results were compared with those derived from patients with neurosensory hypoacusis of vascular origin, aggravated by the recruitment phenomenon, and in the cortical structures of the hearing organ in the case of neurosensory hypoacusis of both vascular and noise origin. Increase of the N2 with observations made on normal controls who were not exposed to industrial noise. CEP were found to give reliable information about changes peak latency may be used for differential diagnosis of neurosensory hypoacusis of vascular or noise origin. Decrease of the P2--N2 amplitude in response to 1 kHz stimulation may also help discriminate neurosensory hypoacusis of vascular or noise origin.
