Studies have proven that ultrasonic sound does not reverberate. This means that once the ultrasonic sound hits a surface, it disappears. Any animal that is living in any kind of crevice, such as a bat, they won't even hear the sound at all.
ADDED. That's not correct: you have misunderstood "the studies" and the basics of sound. Ultrasound will not normally give rise to reverberation because as its frequency rises its absorption losses through the air rise, on top of the attenuation by distance. Some surfaces will absorb sound, but generally ultrasound is easily reflected from any suitable surface, and the bat will hear a sound within its own hearing frequency-range. This is how bats navigate and hunt!
To create an ultrasonic wave emitter to repel bats, you can use commercially available ultrasonic repellers specifically designed for this purpose. These devices emit high-frequency sound waves that are unpleasant for bats, causing them to leave the area. Ensure that the emitter is placed strategically to cover the target area effectively.
Bat echolocation is an example of ultrasonic sounds, as bats emit high-frequency sound waves that bounce off objects and allow them to navigate and hunt in the dark.
Ultrasound
Ultrasonic waves can be produced in the laboratory using a device called an ultrasonic transducer. The transducer converts electrical energy into mechanical vibrations, which generate the ultrasonic waves. These waves can be used for various applications, including medical imaging, cleaning, and material testing.
The ultrasonic device emitted high-frequency sound waves to clean the jewelry.
Not as far as I'm concerned.
They don't work. i would advise against.
No, ultrasonic mosquito repellers do not work. Extensive tests have been run on them. The facts is, mosquitoes don't even have ears. ... i agree they dont work but mosquitoes can defenetly hear. they dont have ears as such but they have complex hearing organs.
No, pest repellers do not work beyond a narrowly defined target area but yes, they do work within their identified range. They nevertheless will be particularly effective in conjunction with row covers and sticky traps.

My experience with electronic pest repellents is that they do work. I have used them to keep possums and rabbits out of vegetable patches, birds and also kangaroos out of orchards. They emit a sonic type frequency that the target animal doesn't like, it doesn't cause them any harm or to humans either. The noise is undetectable to humans. Be Happy, Barry

Ultrasound
Yes
Yes, Ultrasonic liposuction does work wonders for people with a lot of weight to lose. It is very safe and effective and does not have any serious complications.
Infrasonic waves are waves which are below humans hearing range while ultrasonic waves are waves which human beings can hear. Example-bat,dog etc and human beings (respectively)
Bats are known for producing ultrasonic sounds for navigation and communication. They emit high-frequency calls that bounce off objects to help them navigate and locate prey.
