WHITE NOISE IN THE STUDY OF AUDITORY FUNCTION IN COCHLEAR IMPLANT USERS
Petrov Sergey Mikhailovich
Abstract. Implanted patients perceive acoustic stimuli with a new sensory system, so we need to study normal auditory phenomena in CI-subjects. In this paper the spectral summation of loudness was investigated. 6 postlingual implanted subjects gave a numerical estimate of the loudness of the three-channel bands presented to them. The reference point is 10 score of the loudness of the white noiseband of 100 dB SPL. The bandwidth of this band is equal to the frequency range of the implant Combi-40-5200 Hz.
Keywords: white noise, three-channell bands, numerical estimate of loudness, CI fitting, SHCHUP.
