Auditory acuity of aged people living in different environments is tested and compared
The first group consists of the aged people who live together with one's family and are still engaged in one's occupation.
The second group contains those who live in an institute for older people in cities and the third group consists of aged people living in an institute in the quiet country side separated from social and business activities.
Overall results showed hearing acuity of those living in the normal household is well preserved for their ages. This was followed by hearing of those who live in the urban area and the worst was hearing of those who were separated from normal social activities. Preservation of hearing in aged people was found to be partly dependent upon the maintenance of function of auditory activities.
Those who do not use auditory function in daily life are likely to aquire presbyacusis much readly as compared to those who constantly use the auditory function in daily life.
