Bearing in mind that many of us listen at least a metre away from our speakers and that most of our rooms have absorbent furniture, I'd venture to suggest that "in room" there is little coming to our ears much above 12KHz anyway. FM radio is brick-walled at 15KHz and a fair number of LP's have to be rolled away above 15KHz to prent the cutter head taking off. Much used analogue master players have well worn heads and these are only replaced when the 15KHz levels on the master tapes (one of four test-tone frequencies) cannot be brought flat with the adjusters.
