I read somewhere that you lose high pitch hearing first, which is why the young could hear the CRTs when the elderly could not. I tried to google for this (actually DDG) but all I got was SEO spam.

By not needing to design for as wide a frequency range, they should be able to either make them less expensive, or more accurate, or both.

They complained of an irritating repeating high pitched noise that gave one a lingering headache and sense of nausea that lasted for about 20 minutes after leaving the area. If I concentrate very hard I can hear it myself but age and probably one too many loud concerts has rendered that range basically silent to me.
