Program That Blocks Audio From Ad Banners?

i am tired of hearing annoying ads when i go to websites.. i don't mind seeing a banner.. but there is something really annoying when i hear it.. it's prolly cause i'm listening to music and it ruins the song...... bah... please help me i've been looking but all i can find is articles about banning music.. lol... thanks for the help

 

get adblock for firfox (extension). It does what It says

 

i've had it for along time..... but it's not exactly what i'm looking for.. i want to single out sound only...... any other suggestions?
