MaxHart85231281734137 Posted April 17, 2009 Share Posted April 17, 2009 my dad is building a walk in cooler (hes a big homebrewer) he got all the insulated walls from a local liquor store that was reduing there coolers, my question is hes got alot of this stuff left over, think it could be a good sound proffer, or just to break up noies around a room, its about 5 to 6 in wide, with alumium on the top and back and filled with foam???? any ideas?

Axe2Grind123 Posted April 17, 2009 Share Posted April 17, 2009 . . . its about 5 to 6 in wide . . . You mean 5-6" thick, ya? Yeah it would work, recommend covering the aluminum with fabric or something if it will face into the room Link to comment Share on other sites More sharing options...
brianh Posted April 17, 2009 Share Posted April 17, 2009 There are three major things you need to know about "soundproofing" a room, in order of importance: 1. Good isolation from external noise and vibration (weakest at doors, windows, and gaps, holes or other noise pathways in the construction) 2. Low background noise level (in a studio environment, noise is usually caused by HVAC and equipment cooling fans). 3. Appropriate Reverberation Time (RT). This does not necessiarly mean that the room should be encased in acoustcally absorbtive materials - some RT is desirable. When it comes to isolation, there are two things you need to aim for: a) an airtight space; walls, ceiling and floor constructed of materials with significant mass (and therefore low resonance). For instance, hollow stud and drywall construction has low mass and high resonance and therefore makes a poor isolator. But concrete or brick constructions are high mass/low resonance and therefore make great isolators. Coupled with air-tight, sound isolating windows and doors, rooms built this way can make pretty good practice and recording spaces. But to answer your question - freezer insulation could be a decent sound isolation material. The trick would be to make sure the rest of the space is sealed up tight because noise, like water, seeks the path of least resistance and will go right through the most robust wall construction if there are holes or gaps in it.
