What are our senses?

Hearing is one of our 5 senses!

What are some sounds that we hear every day?

© 2011

How do we hear?

We use our ears to hear different sounds in the environment.

Parts of the Ear

Outer Ear

Parts of the Ear

Middle Ear

The middle ear is made up of the ear drum and three bones called the malleus (hammer), the incus (anvil), and the

stapes (stirrup).

Parts of the Ear

Inner Ear

The inner ear is made up of the cochlea and the auditory nerve. The small hair cells inside the cochlea help us

hear the sounds.

What is sound?

Sound travels in waves, called vibrations.

These vibrations hit the different parts of the ear and help us hear all the different sounds!

© 2011

Sound

Sound vibrates at different frequencies.

Frequency is how fast a sound wave vibrates through the air.

© 2011

Frequency of Sound

The vibrating frequency can be fast or slow.

Fast frequencies make high sounds.

Slow frequencies make low sounds.

© 2011

So How Do We Hear?

We hear when sound waves travel through our ear and vibrate the hair cells in our

cochlea.

How the ear works...

© 2011

Sounds can be Loud or Soft•Sounds are measured in Decibels (dB)

•Low dB = Quiet sound•High dB = Loud sound

© 2011

Sound Level Meter

•Measures the dB in the environment

Let’s see what different dB readings we can get!!

© 2011

Sound Level Meter - Quiet

© 2011

Sound Level Meter – “Shhh”

© 2011

Sound Level Meter – “Ahhh”

© 2011

Sounds can be Loud or Soft

•Sounds start to become harmful when they reach:

A. 30-35 dB C. 85-90 dBB. 55-60 dB D. 125-130 dB

Hearing Loss

You can get a hearing loss when a part of your ear does not work the way that it

needs to for hearing all the sounds in the environment.
