This has been happening for some time now. When ever i visit this site at the very top of the page i get a buzzing sound from my speakers, but as i scroll down the buzzing fades to about half.
It doesnt happen on any other site i go to, just here. Any idea what is causing this?

 

The issue is an interference issue or a driver issue with your system that is possibly tied to video/cpu usage. It's not extremely uncommon issue and it's not directly from the site.
