<div>Objectives</div>


<div>To determine the quantitative effects of an Tomatis auditory stimulation
method using of clinical measures of hearing and cognitive P300 evoked
potentials.</div>


<div>Method</div>


<div>Seventeen patients were included in this study. Nine patients received
100 non-consecutive hours of auditory stimulation, in the form of a
personalized program. Eight control subjects did not receive any
auditory stimulation. The patients were subjected to a listening test
and cognitive auditory MMN (Mismatch Negativity) and P300 evoked
potentials test before and after stimulation. The control group was
subjected to two distant listening tests (without any interim auditory
stimulation). The average time between the two tests was quite similar
to that of the patient group. The clinical effects of this form of
auditory stimulation were ascertained on the basis of a multiple-choice
questionnaire.</div>
