A rabbit can hear predators approaching from up to 2 miles away.
To help it hear approaching predators.
The friend above the water will hear the sound of an approaching boat first because sound travels faster through water than through air.
Because the speed of sound travels at +- 1300 km/h and the car that is approaching isn't that fast. So u first hear the sound before the car reaches u.
They use their ears to hear sounds
the denser the medium the faster the sound of speed. it is experimentally proved. for example if a train is appraching and you cant hear the sound you can hear it if you put your head (ear) on the railtrack. but do move quickly if you see the train approaching.....
Susan and Lucy hear footsteps approaching in the snow, followed by jingling harness bells, which indicate that Father Christmas is coming.
well bats have a very good sound detecting system because they can hear their prey or predators approaching better, as a matter of fact i know you have heard the phrase used 'i'm as blind as a bat', well it turns out bats have very good seeing too!!
Rats have excellent hearing that helps them detect predators or approaching threats. Their ears can rotate and move independently, allowing them to locate the source of sound accurately. This keen sense of hearing is crucial for their survival in the wild.

Thanks for the question. This phenomenon may have something to do with the fact that you may be in the approaching car's way, and they may want you to get out of the way. If the horn sounds only as the approaching car reaches you, it may be too late for anything to be done - hence most people opt for a sounding of the horn at some distance away. You hear the sound before the car reaches you because sound travels faster than the car is travelling.
Rabbits are lagomorphs which means they have large back feet, gnawing teeth, and large ears. Since they have large ears, they can hear all the sounds around them. Whenever a rabbit hears a sound, his or her ears turn in that direction. It's their instinct. When all rabbits were wild, they depended on their sound catching ears! So coyotes or another predator could be detected before the coyote has some fast food!
The Doppler effect alters how we hear sound by changing the pitch or frequency of the sound wave when the source of the sound is moving towards or away from us. If the source is approaching, the frequency increases, resulting in a higher pitch; if it is moving away, the frequency decreases, leading to a lower pitch.
