One thing to note about the standard egg-crate-foam (often used in packaging) as "sound absorbing" is its flamability. Highly flamable. There are some very dead former members of the band Great White who will attest to its flamability (burned down a club they were playing in in just a couple of minutes!) I know this because my other hobby is playing, writing and recording music. I did extensive research about cheap sound deadening material for my home studio. I ended up using a rigid fiberglass insulation from Owens Corning 705 series. It is high temperature tolerant, and actually used in industrial mechanical sound reduction. Another thing is that egg-crate-foam only absorbs a very small range of high frequencies, plus it doesn't absorb them very well. As a test, light a small piece with a lighter, then pull the flame away. If it continues to burn... bad, bad, bad.
