Abstract:

Abstract The auditory training with wide - band white noise is a methodology for the qualitative recovery of the hearing loss in people suffering from sensorineural hearing loss . It is based on the application of a wide - band white modified noise . In a prospective study , we have assessed the modifications of the recruitment coefficient in a sample of 48 patients who have followed a program of 15 auditory training with wide - band white noise sessions . The average improvement of the recruitment coefficient expressed in percentage is a 7 .7498% , which comes up to 23 .5249% in the case of a binaural recruitment coefficient . From our results , it can be deduced that the auditory training with wide - band white noise reduces the recruitment . That is to say , the decrease of the recruitment in high intensities both binaurally and in all ears .
