Can iPhone detect ultrasound?

You can't detect any frequencies higher than the Nyquist frequency, which is half the sample rate you are working at. From what I can see, the iPhone won't let you sample at higher than 44.1kHz, meaning that there will hardly be any frequency information above 22kHz.

Can dogs hear ultrasonic?

Ultrasound is sound with a frequency greater than the upper limit of human hearing, which is around 20 kilohertz (20,000 hertz). Dogs are capable of hearing sounds up to 50 kilohertz and possibly even higher, so if you're wondering whether dogs can hear ultrasound, the answer is a resounding yes.

Can a baby hide on an ultrasound?
