NYT story about superhigh frequency ringtones. A new ringtone at a frequency of 17 Khz is supposedly inaudible to most adults, and so highschoolers and others are using it to sneak text messages in school, etc. BUT. An mp3 of the tone is included with the story and I can totally hear it, though it hurts my ears. And I am in my 40s. Can others hear it?
