Ultrasound exists outside our hearing range (20 Hz to 20 Khz). You won’t hear anything if it is around you. But we are known to be able to be influenced by ultrasound that is as high as 100 Khz. You won’t hear it but your brain will. The first thing you will know about it is when you get a feeling of something or your thinking might shift a little and you might say, “now where did that come from”. Just like that. And that could be an ultrasound signal getting through.
Bats communicate with ultrasound. You won’t hear what they are saying unless you use a special microphone that can record high sound frequencies.
The only reason you can hear these bats is because these are “sounds created by heterodyne bat detector.” Heterodyne means to record at a high frequency sound which you cannot hear by an ultrasound microphone and then to reduce it into the hearing range so you can hear it. So there is a lot about ultrasound that goes on in the background that you don’ know about because you cannot hear it but they get to say “hello” to your brain and when they do you will sense/feel it but not hear it.
Below is a random ultrasound recording. No bats but you do get some chatter. See what you think of it?
Living under an ultrasound canopy and you don’t know it.
I transferred this file to audacity so I could do some editing to remove the noise and hear the chatter more clearly.

Base frequency modulation.
Ultrasound is the invisible interface for the human mindbodysoul. Through ultrasound resonance the body in the future can be manipulated to anything it wants to be. Chemical processes in the body could be targeted to carry out specific processes. As you have seen above ultrasound modulation and resonance could take out a tumour. Perhaps in the future also a weapon could be in the making where resonance could vaporise a human being. Drones designed not to carry bombs but ultrasound vaporises. Then ultrasound polygraphs will take over the present version measuring electrical activity and blood pressure monitoring to see if a person is lying. Or realtime spacial ultrasound monitoring people who inhabit a space, say in a shopping centre. Then there is ultrasound to grow new teeth for granma:
Sound: not just for hearing.
Boom Boom Bang Bang with sound.
Unbelievable?
coming up next: the ultrasound “Vapouriser”:
Ultrasound like Dr Who, Invisible Man and Double O 7 coming together.
update: composite investigation.
Electromagnetic induction loop using ultrasound software. Here it is the algorithm that matters as to how it interprets the signal. Remember the final input signal is always electrical via an em induction pickup. The ultrasound microphone does the same, the microphone picks up sound and creates an electrical signal to be fed into the software for processing. The software has an algorithm designed to process a specific type of signal: sound or an em signal but the electrical signal generated is specific to its sensor. The algorithm will processes either as all it needs is an electrical signal. Here an em loop receiver against an in-ear headphone picking up sub vocal murmur. I hardly but silently recited “jack and jill” under my breath. If you looked at me you would have thought that I was just staring into space but there was a gentle murmur in my breath. results: The result of the scan was transferred to audacity to create an MP3 file. The MP3 file is an original with no editing.
