Soundproofing is an assembly. A thicker sheet of drywall by itself is not one.

Meridian Quality Drywall is the soundproof drywall page for Meridian, Idaho. Quiet walls are an assembly: mass, decoupling, and sealant. A thicker sheet of gypsum by itself is not one.
Mass-loaded vinyl, 5/8-inch Type X in two layers, and resilient channel are the usual tools. They only work as a system. Screwing Type X to the same studs as the first layer, seams stacked, with gaps at the floor, is extra weight with almost no extra quiet.
Assemblies that actually change STC
Offset the second-layer seams. Acoustic sealant at the plates, around boxes, and at the ceiling. Put boxes on different stud bays, or use putty pads. Resilient channel is easy to short-circuit with a long screw into a stud; that screw turns the channel into a rigid connector and the wall is loud again.
Townhome and apartment demising walls in the newer Meridian plats are already supposed to be rated and quiet. A single-family house that wants a quiet office is a different, simpler stack. Call with the rooms on both sides of the wall and whether this is new framing or a retrofit.

Common questions
Will one layer of 'soundproof' board stop a neighbor?
A single layer of specialty board helps a little. A real STC bump is mass plus decoupling: two layers, offset seams, acoustic sealant, and either resilient channel or a staggered-stud wall. Skipping the sealant at the plates undoes the rest.
What rooms in a Meridian house usually get this?
Media rooms, ADUs over garages, bedrooms on a busy wall along Fairview or Eagle Road, and the wall between a home office and a living room. Party walls in townhomes are a spec item, not a guess.
Is QuietRock enough by itself?
Specialty sound board adds mass. Without offset seams, acoustic sealant, and usually a decoupled layer, it is still a loud wall. Brand names do not replace the assembly.
