Would be nice if someone more knowledgeable in audiology could chime in. I easily found picrel online and I can hear a sinewave at 18khz on my desktop. I'd more likely bet I am doing something wrong with the setup. I pinged a place in town to see what it would run me to take a test. I'd love it if they could legally certify the results or something or make it publicly verifiable in any way.
