One can only hope that English is not the first language of that author.
To actually understand what's going on here, you have to understand how ultrasound kills cells. It does so by cavitation and heating. In order to get
that effect, you have to have enough power. The power used by the machine in the article is quite high, for rat nards it was 2.2W per sq cm, for 15
minutes. This required a fairly high power machine, putting out 3MHz sound, in contact with the rat nards using impedance matching gel, for 15 minutes
per nard, two times.
That's a bit different than playing an ultrasound mp3 at a few inches away. Had you applied the same power output to, say, your eye, it would have
coagulated as well.
Ultrasounds from and to cellphones?
This link is talking about 20kHz signaling using the speaker - which is very low power and about two orders of magnitude the wrong frequency, and not
coupled to YOUR nards via a proper transducer and gel.
Another different ultrasound application for mobile
And this one's talking about external ultrasound generators you can control by USB links. Not about the phone doing it itself. Hint - you actually
have to read the content, not just scan for keywords
“One of the things I didn’t realize, is 90 percent of the world’s people are in range of a cellphone tower,”
Bees smell fear, the human head weighs about eight pounds.
Adding it all up, it's quite scary indeed.
Only if you don't understand what they're talking about.
