Glad to see people coming up with (new) ideas.
I do not agree to put this function "! Resetrank" You come to play on the server, you keep your course, it is the community side, what you acquire you keep it.
After that if you really have good reason, it seems to me that you can ask a high ranking administrator to do it manually.
For the sounds that you propose, for my part, I'm more to say the least possible. Otherwise you do not hear people talking and anyway there will be no perfect sound for everyone. a lot of work for no great satisfaction.
Again this is only my personal opinion.
