Sound travels down the ear canal then strikes the ear drum creating a vibration. Then the ear drum moves the hammer, which strikes the anvil. The anvil now pushes against the stirrup, causing it to move. These little bones make the sound louder. The anvil causes the stirrup to hit against the cochlea sending sound waves to the inner ear. From there the tiny hairs of the Auditory nerve sense movement of the liquid in the cochlea and sends it to the brain. This sound is processed in the temporal lobe. http://www.childrensuniversity.manchester.ac.uk/interactives/science/brainandsenses/ear/

Why an animal might hear better than a human

# data[].attributes.body
From a baby's sigh to a cruise ship foghorn, the average human ear can hear sounds between 20 and 20,000 Hertz

your family pet can hear about two times better than you!

they can also hear sounds approximately four times farther away than humans.

dogs have a much better hearing range than we do. What you hear at 20 feet, your dog can hear from 80 feet away.

The reason dogs can hear better then is that they have 18 or more muscles that control a dog’s pinna, or ear flap. These  muscles allow a dog to finely tune the position of his ear canal to find a sound, hear it more accurately, and from farther away. For this reason, dogs with upright ears, like terriers, tend to have superior hearing to dogs with floppy ears, such as hounds. It also means that dogs are much more sensitive to loud noises than are humans. Loud noises that are tolerated by humans may be scary or even painful to dogs.

Why do some sounds have a high or low pitch?

1. the stronger the vibration, the louder it is
2. the faster something vibrates, the higher the pitch
3. the slower something vibrates, the lower the pitch

1. The wax moth
2. Elephants
3. Bats
4. Dolphins
5. Cats
6. Dogs
7. Owls
8. Rats
9. Horses
10. Pigeons

The greater wax moths main predator is the bat is its number one predator it's going to need to outwit it with its hearing.

Horses need to have a good hearing as well as they actually have many predators in the wild — they are a flight animal and rely heavily on their hearing, which is much better than their sight. The horses range is 55 herz to 33 kiloherz. They can move their ears in any direction the sound came from.

Pigeons have a low hearing frequency which allows them to detect storms and hear over a long distance.

The ear flaps, or pinnae, are the fold of skin and cartilage that we normally think of as ears. They collect sound waves and send them into the ear canal. Animals such as dogs and horses have bigger ears and can hear more. From http://www.childrensuniversity.manchester.ac.uk/interactives/science/brainandsenses/ear/

# data[].attributes.body
The ear canal is a tube that connects the outer ear flab with the inner ear. Sound waves are reflected by the ear flap and travel down the ear canal to the ear drum.  From http://www.childrensuniversity.manchester.ac.uk/interactives/science/brainandsenses/ear/

# data[].attributes.body
The ear drum is a thin layer -or membrane- at the end of the ear canal. Sound waves travelling down the ear canal strike the ear drum, causing it to vibrate. From http://www.childrensuniversity.manchester.ac.uk/interactives/science/brainandsenses/ear/

# data[].attributes.body
The hammer is a tiny bone connected to the ear drum, and in turn the anvil. When sound waves cause the ear drum to vibrate, the ear drum moves the hammer, which then strikes the anvil.  From http://www.childrensuniversity.manchester.ac.uk/interactives/science/brainandsenses/ear/

# data[].attributes.body
The anvil is a tiny bone between the hammer and the stirrup. When the ear drum moves the hammer, the anvil is stuck and it pushes against the stirrup. This causes it to move. These tiny bones make the sound louder.From https://mix.office.com/watch/13mgauwinjt57

The stirrup is a tiny-the smallest bone in the human body-which is connected to the anvil and the cochlea. From https://mix.office.com/watch/13mgauwinjt57

The cochlea is a snail shaped chamber which is  filled with liquid and lined with cells that have tiny hairs on top-the cells are called hair cells .Once the stirrup hits the cochlea it sends waves through the liquid inside it. These waves move the tiny sensitive which make up the start of the auditory nerve

# data[].attributes.body
The auditory nerve begins in the cochlea, as thousands of tiny hairs. The hairs sense movements in the liquid inside the cochlea and carry this information to the brain, which interprets the sounds we hear. http://www.childrensuniversity.manchester.ac.uk/interactives/science/brainandsenses/ear/
