It's a big pain that "Lenovo Y700-17ISK subwoofer problem" hasn't been solved for almost two years now:

Our environments now are littered with constant meaningless noises, if anything, evolution will just degrade our hearing.
E: if there are new audio chip manufacturers, I suspect it's just because they think they can do it cheaper than others.Last edited by pmorph; 20 January 2018, 06:12 AM.

So unless people with worse hearing will somehow manage to make more children than those with normal hearing, this won't happen.
What is happening is that people with "bad" traits like genetic illnesses (mild or even very bad) or whatever now can still live fine because of modern technology and medicine, so the gene pool is getting more and more individuals with "bad" traits than back in the day. Back in the "golden days" when men were men, women were women and children were exploited in mines and factories, these individuals would die off or not reproduce as well as the ones with "good" traits.
But this has nothing to do with being in a very noisy environment or not.

For example: Czarist Russia had compulsory army service of 25 years. Wanted to skip it? Hard to avoid unless you were clearly physically not 'normal'. Better have some finger or toe missing... or weird enough, extra. Former was achieved by way of an axe and a chopping block, latter was more a matter of genetic luck. And over a time some regions appeared in Russian Empire where a lot of men had 6th digit - they did not qualify for army service, could create families before getting into late middle age and were thus in a 'much prefered' category as prospective husbands.

A 140 dB SNR in a DAC really is 140 dB. That old 10000W PMPO amplifier OTOH was just a 5W DIN A-weighted amplifier. People think that their ears are golden, when they really aren't. But that doesn't matter, it's business. How businesses work, they need to generate revenue and not only a constant stream, but also annual growth, e.g. 8%.

No they are not real. Do you even understand the extreme precision that would be needed in order to create a true 32-bit output of -1.736 to +1.736 volts? That is a span of less than 4 volts that you accurately need to create over 2 billion different levels of. Some of the best 16-bit DACs used in professional equipment ever used was close to 12-bits of performance.
"This first member of the ESS PRO SABRE series sets a new benchmark in high-end audio by offering the industry's highest dynamic range (DNR) of 140dB. The ES9038PRO also offers impressively low total harmonic distortion plus noise (THD+N) at -122dB in a 32-bit, 8-channel DAC."
