Using Acoustic Foam to treat a room.

 It is a common misconception that the funky shaped foam panels we see in recording studios are somehow designed to sound-proof the room and stop noise getting either out or in.

They're not. These foam panels are designed to treat the sound within the room in order that the object sounds can be as neutral and natural as possible without the room adding in all kinds of extra characteristics that will not exist in the intended listening environment.

Peter Mason goes into the subject in much greater detail below.

There is an increasing number of online home-made videos and tutorials showing various aspects of the drum making and drum finishing processes, some of these are are reasonable and some are not so great. Many of the 'how its made' variety give an insight into the major drum manufacturer's plants and processes that are very informative, but use machines and techniques that the small-time or hobby builder can never hope to use. John Dutra's Guerrilla Drum Making represents the first professionally produced tutorial that I have come across regarding Drum making that relies on common or garden tools and techniques - I am mightily impressed.
