I got this information after lot of research...We should say in right ear
It is auspicious to have a darshan of Lord Shiva through the Horns of the Divine Bull on Pradosham days. Recite only Shiva mantra in Nandi's ears (many people recite their woes and prayer requests to Nandi. Shastras indicate reciting Shiva mantra in Nandi's right ears is the right practice. According to Puranas, Nandi's left ear is deaf.

Dr, Can you please explain any proven side effects of living with one ear ? Does it impact ou thught processes and actions?? .I am also like Nandi
Well it all depends on the cause of hearing loss.
If one was born that way then there would be no problems becos the normal ear function usually compensates.
So information is relayed to brain as usual...therefore no real known effect on thought process.
In case of loss of hearing in one ear..one needs to find out the cause..whether it was infective,neuronal or traumatic or part of aging.
Mostly can function normally if the other ear is not as affected ...therefore thought process and actions should not be affected.
But an unproven beneficial side effect of unilateral hearing loss is one can turn a deaf ear to one's wife's nagging!LOL
