It was interesting video.
First, it said that there are two types of listening. Reductive listenig and expansive listening. Many men do the former one and many women do the latter one. I could be convinced this definition well because girls love chatting!! They would continue chatting forever until they were stopped!!
Second, NIHD was also interesting. I was surprised that one in six American teenagers have this disorder. Maybe, I don't have it. But I like listening to music using ipod and turn up the volume especially on the train, so I think I often do what is bad for my ear health. The video said that the sound of Wind, Water and Bird is good for our ear, so now, Iwant to go the place where there are a lot of nature!!
