Basically, a wave will hardly be affected by objects that are smaller than the wavelength. That means that shorter wavelengths are more appropriate for detecting objects.
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.
the bats do not produce supersonic sounds.they produce ultrasonic sounds.Thats the reason we cant hear them
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)
Sound requires a medium, such as air or water, to travel through. In the absence of a medium, such as in empty space, there are no particles for sound waves to propagate through, so sound cannot travel.
In a forest, sound waves are absorbed or scattered by the trees, leaves, and other vegetation, preventing them from bouncing back and creating an echo. The dense foliage acts as a barrier that absorbs and diffuses sound, reducing the chances of echo formation.

i need sound on skype
Sound can.
you cant
There is no air for sound to travel through.

light can but sound cant as there is no air
A shoe.
you cant
You cant.
the sound will get louder until you cant ignore it
