From broad band treatments to bass trapping, Helmholtz baffles and vertical splayed wall treatments it just depends on the design of your room and the needs for your sonic signature.
Whatever it is that you require, contemporary acoustic treatments are the answer.

Fiberglass, Rockwool, Polyester, Cotton, and Sheep Absorption Coefficients
“Measurements are done according to a standard test method such as ASTM C423 or ISO. In some cases, the measured sound absorption coefficient is greater than 1.00. As recommended by the test method, these values are reported as measured and not adjusted. Differences in coefficients of less than 0.15 are not significant.”
Slat Absorbers and Drum Isolation Riser
“I am in the process of building several traps, slot resonators, etc. for my new home studio…and I am seeking HELP! I would like to know what everyone here recommends in the way of treating the room. “
Standard EN 12354-6
“Contains a method for estimation of sound absorption and reverberation time in enclosed spaces. Annex D of the standard gives a method for estimation of reverberation time in spaces where absorption coefficient varies much between the pair of opposite surfaces. “

SuperChunks bass traps: How to make
“The SuperChunk is accomplished by cutting up mineral fiber panels into triangles and then stacking them so as to fill the entire corner from floor to ceiling. Panel thickness is immaterial, but the thicker they are the fewer you have to cut, and thicker ones may be cheaper per volume.
The interaction of acoustic treatment in an experimental sound control room. J.A. Fletcher
“In small studios or control rooms the predicted reverberation time is often significantly different from that measured. The prediction is normally made from the absorption coefficients of the acoustic treatment and other materials as measured in a reverberation room.”
