Not so sure about that, mixing engineers have to do very precise manipulation of sound and there’s plenty of them working well into their 40ies and beyond. While of course aspects of your hearing deteriorate, it should still be pretty simple to pick out the artefacts of compressed audio if you’ve gotten attuned to them at a younger age… At least for heavier compression, something like a 320kbps MP3 or 256 AAC is hard to distinguish from lossless but that’s also true for young folks.
