Unsound

On the one hand, the term unsound refers to methods which are dubious, without reasonable foundation, faulty, unethical, or which follow bad practices. On the other, unsound names inaudible frequencies, whether sound at the peripheries of human audition (infrasonic and ultrasonic) or syntheses as yet uninvented, unheard, or rendered audible only by auditory prostheses.thecontemporaryjournal.org
