I would like to refer to this film I watched about sound and listening.
First of all, I knew that there is a hearing disorder called NIHD. As I often listen to music with sound loud. But so far, I have never had any kind of trouble as it was shown in the film.
It is a good idea to listen to the sounds of nature, those which are produced by Mother Nature. They ease us. As I have been beset by many harmful and irritating sounds since I came here, I will just listen to natural sounds of nature when I go back to my hometown.
