First, a BIG THANK YOU to Viffermike, garyinmotion and everyone else who has contributed a LOT of good information regarding this topic!
I brought my 2019 CGTS home in early November. It hibernated. Now the weather has finally improved and I drove it again yesterday to run some errands. I was struck by the general sound level in the car (with the windows up). I was somewhat disappointed by the drumming, droning sounds I was hearing. I wondered why Porsche hadn't done a better job with the sound deadening. Years ago, for car and airplane travel, I purchased a pair of noise-cancelling headphones to attenuate the very types of sounds that I was hearing in my new car. This morning, when searching for pictures of the rear bumper beam for a trailer hitch that I am designing, I ran across this thread. I immediately went out to the garage and checked my car. There is no Soundaktor control box attached to the left-rear bodywork as in earlier cars. But there was a 7.5-amp fuse in position ten of the top row of the fuse panel in the right-rear bodywork. I immediately pulled the fuse and went for a drive, accompanied by my wife (her first ride in the car). The difference in sound was immediate and impressive. As others have noted, the sounds are now much more natural, clean and pleasant. The fuse will not be going back into the panel. And I don't care where the control box is located.
To make fuse removal and installation easier, simply use a fuse puller. They are inexpensive and are available at auto parts stores. They are also available for free at junk yards--no respectable junk yard counterperson would charge for a fuse puller. I have included a picture for reference (two fuse pullers shown).
