Is thr some bug that SPAM sounds play auto on IF page opening

As u can see I have opened this forum itself, 'suggestions and comments' and ear splitting noise came with the bell option u can see where I have used the suggested (Ctrl+M) to mute it. It has been happening for a couple of days to me now that whenever I open random IF page these loud BG noise (I think from the ads on the page) plays! It is annoying not to mention painful cz I'm wearing headphones and it is just so loud!!

Just see if there is some sort of bug!

PS: Only happened on IF pages. So it is not in my laptop!
