Sound treatment products include, but are not limited to, Acoustic Panels such as our R3B Wall Panels, acoustical foam products with varying convoluted facing, patterns, shapes and colors. Probably the more versatile. Then there are acoustic baffles which are primarily hung on ceilings and act as a sound diffuser & absorber. Many baffle systems can be found in industrial settings.

Soundproofing on the other hand is different in the sense that the primary focus is preventing sound wave pass-through.  Massive, dense materials and composites like thick concrete and iron provide good sound wave pass through resistance measured as   "TL" = transmission loss (the amount of dB SPL or sound pressure attenuated by an object or material).

In hind side though, products like "Hebel" made by companies such as CSR Bradford for example provide good sound proofing capabilities whilst being fairly light in weight.

There are many methods and techniques used in soundproofing buildings, such as multilayer plaster combined with acoustic insulation and brick or steel reinforced concrete. In recording studios, the usual soundproofing method will be "false floors, ceilings and walls. This method works quite well when combined with acoustic panels on the walls or ceiling to control reverb and slap echo and also provide extra transmission loss capability. Remember, sound pass-through reduction = soundproofing. Sound / echo / reverb absorption = acoustic treatment).
