In the lecture, there was a mentioning of a hearing disorder called NIHD. I myself may be one of those that have NIHD since I'm in a rock band and I was using cheap earphones...
And the day before we watched the lecture, I found this application on my i-phone called "Sea". It's basically the sound of waves just playing, but I remember the WWB's (Wind, Water, Birds) which are called harmonious.
So now, I'm trying my best to protect my hearing by doing the 7 things that were suggested. I'm also thinking of buying earplugs to protect my ears during my band practices.
