Hearing loss in rural population : the etiology
Abstract:
Out of the five sensations, hearing is a major one. The gross impairment of hearing especially in the children lead to lack of development of speech and makes the person grossly handicapped. This study consisting of 758 cases from rural area having hearing impairment, was aimed to findout the various aetiological factors resulting in hearing loss. 62.2% of cases belonged to 0-20 years age group. Otitis media (57.25%) was the commonest aetiological factor. Conductive hearing loss was the commonest type of hearing loss in otitis media. 86.17% cases of otitis media were in age group 0-20 years.

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...

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...
