Abstract
Crossed and uncrossed acoustic reflex amplitude was measured in 99 adult subjects. Minor middle ear dysfunction profoundly influenced acoustic reflex amplitude. Reflex amplitude in subjects with minor impedance abnormality was, on the average, decreased by 68% in comparison to a matched control group. There was a complex relationship among age, sensorineural hearing loss, signal bandwidth and acoustic reflex amplitude. Sensorineural hearing loss differentially influenced acoustic reflex amplitude for young versus older subjects. Résumé Nous avons étudié l'amplitude du réflexe acoustique en stimulation ipsilatérale (ou directe) et contro-latérale (ou croisée) chez 99 sujets. Nous avons pu constater que: 1) un léger dysfonctionnement de l'oreille moyenne (surtout le type Ad ou avec pression négative de 50 à 100 mm H2O) influence l'amplitude du réflexe chez un certain nombre de sujets; 2) s'il existe un rapport complexe entre l'aˇge, l'atteinte sensori-neurale de l'audition et la largeur de bande du signal, toutefois une perte sensori-neurale semble influencer différemment l'amplitude du réflexe acoustique chez le sujet jeune et chez le sujet aˇgé.Keywords
