It depends on what you are trying to do and how much of the room natural resonance characteristics need to be controlled. A lot of music studios have quite large parts of the studio free of sound deadening material, since using too much material can make a room sound dull and lifeless for an acoustic set, rather like an anechoic chamber. It also depends on the foam material, its surface texture, and the foam structure. Polyurethane-type, open cell foams are best. Polypropylene foam with closed cell structure is too elastic to be suitably efficaceous, whilst open celled polypropylene will work, but to a lesser extent than polyurethane. Expanded polystyrene has relatively little sound absorbency, tending to bounce the sound in a manner determined by its surface texture. Thin foams will tend to absorb only high frequencies, whilst thicker foams will attenuate low frequencies, too. Most acoustic foams are 2 to 4cm thick, although 1cm or less of foam will produce noticeable effects. Furniture, curtains, rugs and carpets can have quite a marked influence on room resonances, as will people. It is also worth considering the type of clothing people wear in the studio; "quiet clothes" made from natural woven or knitted type fabrics are better than synthetics. Jewellery can be surprisingly "clinky". I have seen studios with egg cartons on the walls, and people have considered the results to be satisfactory.

This link might give some ideas, and contains a further link to some limited acoustic data for their foams.
