I'd say most 25 year olds would be tapering off at the 20kHz end around 14-16kHz and at the bottom around 30-50Hz
Yeah. 20-20kHz (huh...20/20 for perfect eyesight, 20/20 for perfect hearing) is the reasonable absolute extents someon in their prime could hear. Obviously there would be a few outside those bounds, but the vast majority of people would be well within them, obvsiouly heavier tapering at the higher end than lower.
