Right ear hearing-loss was seen in 147 cases and left ear in 130 cases. 48 individuals had no hearing-loss, 39 participants had unilateral hearing-loss and 119 participants had bilateral hearing-loss. Most common type of hearing-loss observed was mild hearing-loss 124 participants had no dementia, 82 had dementia. 60 had mild cognitive impairment and 22 had severe cognitive impairment. 49 out of 82 participants with dementia had bilateral hearing-loss.
