(possible offtopic rant)
I find it fascinating that canned music has become almost ubiquitous these days. Wherever I go, some 80% of the people surrounding me are wearing earplugs and are apparently listening to something. Yes, I'm guilty as h€ll myself, I listen to the radio on my cellphone on every bus commute. And I have about a thousand music albums at home, on vinyl, CD and harddisk, and I listen to some of that almost daily.
However, when it comes to wearing earplugs while in the wild, I just can't understand why. When I'm out in the nature, I want to experience nature fully, though all my five senses. I don't understand why someone would like to listen to canned music instead of the birds and the animals I encounter. I love the (relative) silence underwater; no-one can talk to me, and the only sound I hear is my own bubbles. To me, that's an almost Zen-like experience and adds to my love of the underwater world. Jacques-Yves Cousteau even used that feature in one of his books ("The Silent World", well worth a read or three).
I guess I'm showing my age here, but I'd recommend the OP to at least try to actively experience the lack of sound - at least sound which we are able to hear - underwater. It might well be a rewarding experience.
