Good morning everyone! And thanks in advance for the help; D

I would like to know the answer to any of these questions; D

a) Could an ultrasound be broadcast on a radio or TV station? How? if possible, I've heard it, but if you look at the range of frequencies in which the radio operates like TV does not seem possible

b) The standard speakers, whether radio, car, TV, etc ... could play it? Maybe something between 19000-20000MHz

c) Any page where you can encode or encrypt audio?

d) Any application or website to generate ultrasound?


Greetings and thanks!!! ; D

Why are you asking ? Seems a bid odd to me to want to reproduce ultrasound
a) Could an ultrasound be broadcast on a radio or TV station? How? if possible, I've heard it, but if you look at the range of frequencies in which the radio operates like TV does not seem possible
I think they have a high pass filter.

b) The standard speakers, whether radio, car, TV, etc ... could play it? Maybe something between 19000-20000MHz
If you mean HZ not MHZ most speakers can reproduce that. TV probably not, radio no, with a high end car system maybee-
If you mean MHZ No. only one speaker can reproduce very high frequency that at higher levels: https://www.lansche-audio.com/produkte/plasmahochtöner/

I don't know- But I can tell you some things about encryption of police radio in germany.


d) Any application or website to generate ultrasound?
