[Acoustic distorsion products: technic, reproducibility and audiometric value. A new technic for the clinical evaluation of hearing].
Acoustic distorsion products are sounds emitted by the cochlea, in relation with the outer hair cell properties and the micromechanical properties of the Organ of Corti, in response to an acoustic stimulation by two primairies F1 and F2. Acoustic distorsion product 2F1-F2 have been recorded in two populations: 10 normally-hearing subjects and 10 subjects with pure sensorineural hearing losses. Three points are discussed: (i) the test-retest reliability, (ii) the clinical tolerance and (iii) the clinical applications of this test.
