To assess clinical utility of the distorsion product emission, 69 subjects were examined. Experiments showed in general a significant relation between the presence of distorsion products and the hearing losses. However the correlation coeficients did not exhibit higher values than 70 %. Therefore simple conclusions about the hearing threshold of an individual ear can't be drawn from a single distorsion product measurement.
