Sound waves are collected at the outer ear.... it funnels the sounds into the ear canal
Waves allow us to hear (sound waves) I hope that helps a little :)
It helps you by, if the phone rings you hear it. you can listen for danger
YES its used a lot in subliminal messages
Ultrasonic is sound of a higher pitch and shorter wavelength than humans can hear.
Ultrasonic waves are sound waves with frequencies higher than what humans can hear. Sound waves have frequencies of about 20,000 to 100,000.
the range of sound frequencies that humans can hear is about0to200Hz
Sound Waves are collected by the out ear and channeldeed along the Ear canal to the ear drum,
typically 20-20000 Hz - but this range will decrease with age
Audible sound is what is actually heard. Some people will interpret audible sounds differently depending on their ability to hear as well as their perceptions. Animals can "hear" sounds that humans cannot hear. There are ranges of sound that are normal for humans.

If you mean a noise humans hear, it is spelled sound. The gun made a loud sound.
No, they just use echolocation to tell where things are. Echolocation is making shrill sounds that humans can't hear that bounce off things. The dolphins have special organs that allow them to hear these sound waves.
Sound waves accessible by humans are attenuated in water.
To know if a predator is coming
it creates gaps in the air and then goes to your ear
The sounds animals can hear is based on the frequency that the certain animal can hear. For example, dog's can hear at much higher frequencies then humans can, so if a sound is made that is above our capability of hearing, we will not hear the sound, but the dog will.
