The website wouldn't load for me. As for the sound, I recommend not using it. If one of your visitors is listening to music or something, then the sound would interfere with that. It might annoy the visitor. Oh, and the browser I'm using is Firefox.
Your site redirects to the Adobe shockwave download page, if you want to use the sound on your page then you should provide the way for the visitor to switch the sound on but you should not enable the sound by default.
