Well, the dB scale was once created on the basis that 1dB was thought to be the "just noticeable difference". Off the top of my head, I think trained listeners can actually notice differences of 0.3 dB, though this sort of thing is going to be frequency dependent too.

The eq-adjustments you'll find online often have adjustments ranging from 1 to 6dB in different frequencies. That's enough to notice.

Comparing settings/devices, it's very easy to notice. Just play some music on your laptop/phone speakers and move the device around a bit, and you'll hear striking differences in highs and lows.

However in isolation, I think most people wouldn't be able to say if a particular sound source is "good" or "bad". It takes a while for you to clock that, no, it's not the teams/zoom call that has bad quality, it's your headset that's dropping mids.

But can they notice the difference on a random track, not on special test audio? Probably not.

My laptop has speakers directed downwards, so putting a palm under it (to reflect sound upwards) increases the quality.
