Almost all loudspeakers are designed with amplifying circuits, or output speakers, or both, that would not magnify sounds in the ultrasonic frequency (over 20 kHz).
the bats do not produce supersonic sounds.they produce ultrasonic sounds.Thats the reason we cant hear them
Humans cannot hear ultrasonic sound because our ears are not sensitive enough to detect frequencies above 20,000 Hz, which is the upper limit of human hearing. Ultrasonic sound waves have a frequency higher than 20,000 Hz, making them outside our audible range.
subsonic is lower than 20Hz, and hypersonic(aslo called ultrasonic freq.)is higher than 14000Hz-16000Hz(you cant hear ultrasonic freq.,some people hear 50-14000,some 150-16000, even some like me hear 20-16500)my specter of hearing freq.is 32-16347Hz(I have been on tests)
i think you cant classify electro magnetic waves. all em waves have sam energy.
to produce vocal sounds you have to keep singing but try not to sing to much that you strain your vocal sound to much so that you cant sing any more that happened to me

Actually you can. A photovoltaic cell (a.k.a. solar panel) does precisely that.
Humans cannot hear ultrasonic sound because our ears are not sensitive enough to detect frequencies above 20,000 Hz, which is the upper limit of human hearing. Ultrasonic sound waves have a frequency higher than 20,000 Hz, making them outside our audible range.
Heat waves (infared) and sound waves.
vibrations caused by the sound waves travel thru the water making the water vibrate causing sound. that is why you cant hear someone talk under water at great distances. the water is denser than the sound waves
9000
yes i cant answer it
Ocean
s waves cant travel through it
men cant produce
uv rays can give u sunburns but radio waves cant
Its not cause they are wild enough, NOAnimal cell cant produce sugar because they are not photosynthetic.how is it that it is cause they are wild, wow
