Where isolation performance is the whole point — and a partition that is merely 'acoustic' will not be enough.
Studios are the one project type where the partition is not a background element but the main acoustic instrument. A vocal booth, a control room and a live room all need different characters: one must isolate almost completely, one must allow controlled listening, and one must keep instruments from bleeding into microphones.
The difficulty is that studio isolation is a system problem. Panels alone do not achieve a high Sound Reduction Index; the result depends on mass, decoupling, sealing at every edge and — most of all — on how flanking transmission is handled. Air conditioning ducts, cable penetrations and structural connections routinely undo an otherwise excellent wall.
Studios also impose a practical constraint that other projects do not: the space is small. The partition thickness, the depth of the cavity and the space lost to isolation all reduce usable floor area, so the acoustic target and the interior dimensions have to be designed together.
A laboratory rating is measured in ideal conditions. In a small room the installed performance is what matters, and it depends on sealing, flanking and workmanship. Ask how the supplier supports site performance rather than only quoting a single number.
Isolation improves markedly when the two faces of the wall are mechanically decoupled, typically with independent stud frames or resilient connections. This is a construction detail that should be specified explicitly, not left to chance.
Small gaps dominate the acoustic result. Head, base and perimeter details, plus every cable and duct penetration, must have a defined sealing method that survives installation and later service work.
Sound travels around a wall through floors, ceilings and adjacent structures. Good isolation requires that these paths are addressed — otherwise the partition's performance is limited by the building, not the product.
Drums, bass and low voices carry energy that is hard to stop. A wall rated well on speech frequencies may still transmit low frequencies, so the specification should reflect the actual sources the room will hold.
High isolation needs mass and depth. The required wall build-up competes with usable room dimensions, so it should be resolved at design stage rather than after the layout is fixed.
Quoting a laboratory rating as if it were the installed result, then discovering on site that sealing and flanking were never resolved.
Resolving the wall in detail but treating air conditioning ducts as an afterthought, which becomes the dominant noise path.
Specifying heavy panels on a structure that cannot carry the load, forcing a late change to a lighter and less effective system.
Designing the room before the wall build-up is known, leaving too little space for adequate isolation.

There is no single figure. A control room adjacent to a live room and a vocal booth next to a corridor have different requirements, and low-frequency content often sets the practical limit. The target should be set from the activities on each side and the background noise that must be maintained, then checked against what the wall build-up can achieve in that specific construction.
No. Panels are one part of a system. Isolation is usually limited by sealing, flanking paths and structural connections, so the detail of how the wall meets floor, ceiling and adjacent walls matters as much as the panel rating.
They can, where the design allows for the mass and decoupling needed. The advantage is that the room can be reconfigured; the risk is that demountable joints are harder to seal consistently. If demountable construction is required, the sealing method at joints and edges should be demonstrated rather than assumed.
Ducts must be treated as part of the acoustic design, typically with lined ductwork, silencers and careful routing. A partition alone cannot control a path that passes around it, so the duct strategy belongs in the same design conversation as the wall.
