Tim: Today, we're gonna show you how to soundproof as well as insulate the walls. Now, there's a variety of products you can use, of course. Acoustic padding, fiberglass batting, or very unattractive flannel. [points to Al's shirt]
Al: The easiest way to install your insulation is during construction, before you've put up your dry wall.
Tim: However, if the dry wall's already been installed in your home, we suggest the foam injection method. Heidi, the foam injector, please.
Al: Here you go, Tim.
Tim: Thank you, Heidi.
Heidi: You're welcome.
Tim: For this method, you're gonna have to drill some holes.
Al: But first you wanna find a stud. [Tim dances] I said "stud," not "dud."
