Testing whether some humans can hear high frequencies inaudible to "normal" humans

Dear List,


My friend thinks that his child can hear frequencies that are inaudible to other humans because of which he sometimes reacts with alarm that no one else understands. Is there a way we can verify this systematically? In my electronics lab during my undergrad one of my friends tested my hearing by varying the frequency output of a signal generator. Is there  a possibility of doing that on a PC?


Also, I would highly appreciate any references on music therapy for language delayed children. I am interested in vocal music training in particular but would appreciate any general music training as well for therapeutic purposes.


Best Regards,
