Progression of sensorineural hearing impairment in aided and unaided ears

Abstract:
The possibility of "adult onset auditory deprivation" has been proposed as a condition of extensive deterioration of speech discrimination in unaided ears. Pure tone thresholds and speech discrimination were studied in a follow-up examination on 500 patients using hearing aids unilaterally. The follow-up time ranged from 5 to 24 years. In average the same amount of deterioration was obtained in both ears. Deterioration in pure tone thresholds increased after the age of 80 years and speech discrimination after 65 years respectively. The results obtained gave no support to the concept of adult onset auditory deprivation in unaided ears.

Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of their outer...
