High frequency auditory threshold study in normal individuals from 12 to 19 years old

Abstract

This work had as a proposal to determine the high frequency auditory threshold (9000 to 16000 Hz) in normal listener individuals, from 12 to 19 years old, being 28 female and 34 male. Of the 62 pacients, 17 were eliminated (8 men and 9 women), because they demonstred some kind of problem on their audiometry and/or on their imitanciometry. All the 45 individuals went through audiologic anamnesys, meatoscopy, basic audiologic assessment and high frequency audiometry.The results demonstred: a) there weren‘t significant statistic differences between the sex ears variables; b) the auditory acuity decreases progressively as the tested frequency gets higher; c) the auditory threshold remains stable until 10000 Hz frequency, occuring a gradual rasing of this thresholds beginning at the 11200 Hz frequency.
