Think I read that the inverse scoop of our ears sensitivity to sound (google ‘Fletcher Munson curve’) changes as sound gets louder.
It gets flatter, which means that we tend to like a scooped Eq at low volume but need it flatter at high volume to achieve the same perceived sound.
There’s more to it than that, in terms of a band mix etc, but in terms of a soloed bass track this does make sense of why we like scoop in the house, flat on stage.
