Abstract

The authors found that 34.7% of person with no subjective hearing problem showed some hearing loss on their pure tone audiogram. Refering to their age, it was observed that below 40 years the incidence of the cases with hearing loss was minimal (2.5%) and independent to age, and over 40 years hearing loss appeared in increasing incidence with increasing age. The incidence was about 30% in subjects of ages between 40 and 49 years, about 60% between 50 and 59, over 90% between 60 and 69, and over 70 years all subjects showed hearing loss. The authors concluded that it must be very important to consider this fact in diagnosing the cases with hearing disturbance at the otological and/or audiological clinic.
