Tell me if you hear anything. It's an MP3 file (really small), of a ringtone that students in the UK have been using to receive phone calls while they are in class without their instructors knowing. Apparently older people cannot hear it at all - but teenagers can because their hearing has not yet degraded. I already listened to it...and heard this high-pitched squeel which is really annoying (you feel it as much as hear it), and I am a lot older than a teenager. But my dad and my uncle could not hear it at all - even when I turned my computer speakers all the way up (although the dog was glaring at me and her ears were cocked).
