I don't have any kind of real gear to measure and tell you that, I can only guess. I also don't think it's a linear decrease across entire rpm range.
I can def say it's more than 2%
20 or 30 maybe? Who knows.
To my ears, it seemed that bottom half of rpm is where most of the changes are. 1.5k - 4k rpm car sounds way to quiet.
At 3000 rpm it sounds about the same as 1800rpm with active sound on. With peak torque kicking in at 1800 rpm, there's just no need to cruise above 2k.
