I don't see the problem with the sound. In the 1980s we had turbo engines, they probably sounded similar to the today's ones and nobody complained.
I believe that today's public got spoiled by the V12/V10/V8 sound of the past 25 years but then I wonder how come that the 1980s public did not get spoiled by the atmospheric engines used by 1985. Probably because the transition was gradual, we had mixed grids for a few years until the turbos fully took over.
Believe me: the turbo engines of the 80's sounded better.
The big difference is that they had two turbos, one for each back of cylinders. So you had two exhausts and two pop-off valve outlets, one of each on each side of the car. The current cars have one big tube in the center of the car.
I am no specialist in physics and sound waves but I recall from my physics lessons that when you combine waves (light, sound) that the resulting wave can be entirely different.
Maybe something like that is happening here as well, combining all the soundwaves into one turbo first and then into one exhaust. is there a soundwave specialist among us who can add something to this. Either make my theory (and me ) look rediculous or tell mare about it?
As for your theory that the public got spoiled over the years, I think that could indeed be the case.
But the atmo engines used in 1985, that were a few races by Tyrrell with a 3 liter Cosworth. No atmos races in 1986 and from 1987 an the 3.5 liters were phased in. The majoritynof them also being Cosworths and the occasional Judd's. the moment that all noise hell really broke loose was when in 1989 you got the newly desegined Post-DFV era atmo engines, including the V10s by Honda and Renault. The first generation of the screamers came along in 1989 but the didn't revv abouve 15000 rpm initially, leta alone the 20000 of the last V10s..
Like you stated, it happened gradually. I wonder if the most staunch supporters of the 2004/2005 V10s and the latest V8s would be that excited about the 1989 V10 and V8 engiens of the day. ther revved slower, thus screamed less and were not as painfully loud as the latest of the breed.
I felt the 1989/1990 breed of engines to be more musical. because of having a somewhat longer stroke, they had more torques and a larger useful rev band thus were more driveable. The 19000 rpm generation had so little torque at lower revs that they coudn't even idle at the rev levels of the past anymore, hence had a narrow useful rev band thus did nothing else but scream because of the necessary high revs to prevent stalling.
As for why there was no complains about less noise with the advance of the turbos in the early 80s. I don't know exactly why. But I do recall from that time that many liked the interest it caused, turbo was a hype at that time, you knew the cars who had such engines were more powerful and faster, And engine management wasn't that well as in later years so in the early years of the turbos you could soe some fantastic firworks coming from the tail. Spectacular to watch! it was a trill to sit near the end of a straight and see the cars slowing down and disappear in the turn.
But if these engines had come at the expense of atmos' that sounded similar the the last V8's and were as noisy, I honestly have no idea what the reactions of the public at large would have been then. The fans of that time were entirely different at that age that the current fans are at their current age.
