I don't know what you could do.. but the ads with the sounds really suck.. they are so damn annoying.. I like listening to music while surfing the net.. and when those things play it gets really annoying.
ah the ads are so annoying. I can barely stand to browse since I have headphones one. Its the flash ads at the bottom that are making the sound. Usually you can opt out of sound ads and such when dealing with ad affiliates. Sometimes you have to send them and email asking them though.
