I believe when they refer to those panel for sound absorption the manufacturer is using them more for "acoustics" not "isolation"
Well when it comes to sound isolation I will take the opinion of Ted White and the guys over at www.soundproofingcompany.com
and according to them ( soundproofing is their business mind you
) you would get more soundproofing with a single layer of drywall compared to using a drop ceiling ( assuming of course that you put the pink fluffy stuff in the joist cavity in both instances to stop resonances ) ... kick it up a notch and add 2 layers for more mass and you are really starting to take care of mids and high frequencies and some lows ... add green glue between the 2 layers of drywall and now low frequencies are being tamed ... better yet use RSIC/hat channel and decouple the drywall while doing all the above
