True, but testing your hearing in the ultra-high frequencies gives you an 
early warning sign that you are starting to have hearing damage.  Also, 
early detection of hearing problems, especially if they are only in one ear, 
can be an early warning sign of other medical problems such as Meniere's 
disease or acoustic neuroma (tumor on the auditory nerve).




/ I'll also buy the statement that in the end our work is about human 
hearing and listening... since regardless of how well a visual route can get 
you down the same road or not.... you cant appreciate the sound of music 
without your ears.
