I feel like people always feel attacked when you point out that a difference probably isn’t real. But I think we need to stop saying you don’t hear it. Human hearing is clearly not merely the process of tranducing sound pressure. You cannot separate objective “sound pressure at the ear drum over time” from whatever other post-processing happens in your brain, and the latter has been repeatedly established to be a significant factor, which you can test for yourself easily enough if you doubt it. This makes it easy to make the attribution error that something is producing a different sound wave, rather than merely changing the cognitive aspect of “hearing”.
