Just out of general info, Rod "never uses acoustic caulk"

What should I use to fill gap around doorframe for best isolation?

As JF said, the two are not interchangeable. And neither GG nor construction adhesive "stop vibrations".

Since the greats Eric Desart and Rod Gervias have covered the topic i will just link their thoughts.

Rod/eric desart on green glue, great read.

Rod-Adhesive is only a disadvantage

Double drywall

Rod never uses construction adhesive in his builds

Isolation: Wall structure stability

Rod green glue vs adhesive

Any Green Glue Users care to comment?

Rod don't use regular glue for drywall, glued mass acts like a single sheet, unglued layers do not.

Double drywall

If creaks are an issue there are techniques to fix it, including headless screws, and screwing up from the underside of the sheathing. The Wyle report specifically states that adhesive on studs makes the assembly worse.

IR-811 shows floor assemblies, and tests with screws not partially unscrewed.
In general construction practices. Whether it be residential or commercial. We glue the subfloor down to the joists as well as nailing with 2 3/8" nails To make sure that over time the floors dont creak..... this is a fact. Whether it applies to acoustics in some way, im only assuming that itd be related. Other wise there wouldnt be a product like green glue.
