Why do animals hear sounds that humans can't? what kind of sounds are they?

Question

My kid is looking for all the sounds that only the animals can hear and of course what are those sounds
Thanks!!

Answer 1

HUMAN HEARING SUCKS,.. that's why >.>

You think the world is limited to your senses?

There are Animals with more then five senses. Cats have atleast 7 Senses. It's difficult for humans to lable them, name them, say how they work, or find ways to messure them because being humans.. they lack these senses.

Two such senses, for cats, are seeing through the ground clear down to techtonics and what is described as seeing smells.

We can't messure animal senses very well because we build things to messure around the limits of the person who makes the messurement system. One of my ears has hearing off the human messurement limits. The other is off the average test limits but not off the limits of the best hearing test for humans. Part of these better test require things that do not depend on the hearing of the testER.

Answer 2

well, sound perception depends on the animal's ear structure. some animals can hear ultrasound (at least 20kilohertz) such as mice, and other animals can hear infrasound (below 20hertz) such as whales.

human hearing is limited to somewher between those ranges. and even then, human hearing is affected by age; there was recently a "buzz" about the "kids only" ringtone--it was a cell phone tone too high in frequency to be detected by the average adult, but about all teenagers could hear it. highschool kids used this ringtone while in school to get "silently" alerted for calls and text messages.

Answer 3

Animals can hear higher and lower pitch frequencies than human beings can as well as having larger ears that are better suited to catching sounds gives animals an advantage over human hearing.

Answer 4

* It varies by species. Dogs hear the higher frequencies (ever hear a dog whistle? Me neither). Very low frequencies carry further and are used by elephants to communicate.

Same philosophy goes for sight. We (humans) have a rather narrow range of frequencies we can see (400 to 700 nm). Mant critters can see into the ultraviolet (flowers have a significant ultraviolet signature that bees and butterflies can see), and others see into the infrared (essentially heat).

Answer 5

The sounds that the animals make that we do not hear are ultrasonic sounds (bats), and subsonic (elephants).

Those of course are only examples of two types of the animals...there are others.

Animals of course hear them, because they communicate with the sounds, or use them to locate prey.

The subsonic noise an elephant can carry miles over the savanah. So too can the sounds of whales, only through the oceans.

Answer 6

Dogs can hear frequencies higher than what people can hear. There are very high pitched whistles that people use to call dogs. Dogs hear them and respond - people have no clue they are being used.

Answer 7

Dogs can hear sounds up to 16K cps; cats, up to 20K; bats, up to 100K. The bats use these high-pitched sounds for echolocation.

Answer 8

Really high frequency or low freqeuency stuff that's outside our aural range.

Just saying "frequencies that are outside our aural range" would do in a pinch.
