You could. But it holds no water Ben.

If you ask someone to first listen sighted and they say they can hear a difference and then introduce a screen to remove visual bias, and then ask again, the only variable is the introduction of a screen. Any test-induced stress (ââ'¬Å"the act of forcing yourself to listenââ'¬Â) is a constant both sighted and unsighted. Beige cloth covered screens do not cause people to suddenly and inexplicably loose their faculty of critical listening.

This is the anti-scientific sentiment put about by John Atkinson of Stereophile, who of course has much vested interest to do so.
