All About Deafness

Holland High School

Deaf Education

Outer ear
Outer Ear

The Outer Ear is the part of the ear that you see.

This part of the ear is shaped round so it can send sound to Middle Ear.

Without the Outer Ear shape-round, we wouldn’t hear as well (the sound could become faint).

The Outer Ear sends sound to the Middle Ear.


Middle ear
Middle Ear

Inside the Middle Ear are 3 little bones called the Hammer, the Anvil, and the Stirrup.

The 3 bones are connected to the Ear Drum.

When sound waves come into your Middle Ear, it causes the Ear Drum to vibrate like a drum.

These vibrations can make the 3 little bones move as well.


Inner ear
Inner Ear

The Inner Ear (Cochlea) has 3 parts.

In the Center of Ear called Vestube.

Inside Vestube there are little hairs and liquid.

When the ear drum starts to vibrate, the liquid moves and the hair moves to make the message send to the brain through the auditory nerve.



Understanding your audiogram
Understanding your Audiogram

Audiograms inform you of your level of hearing based on a test of various sound frequencies given by an audiologist (hearing doctor).

Your hearing is based on decibels (dB) at each frequency or (Hz-hertz).

To test your hearing - click the link below.

All about deafness

The yellow banana shaped figure represents all the sounds that make up the human voice when speaking at normal conversational levels.

  • Near total silence - 0 dB

  • A whisper - 15 dB

  • Normal conversation - 60 dB

  • A lawnmower - 90 dB

  • A car horn - 110 dB

  • A rock concert or a jet engine - 120 dB

  • A gunshot or firecracker – 140 dB

    Above is the decibels or dB of sound for each area of hearing.


Ranges of hearing loss
RANGES OF HEARING LOSS that make up the human voice when speaking at normal conversational levels.

The audiogram shows the ranges of hearing loss for adults. The ranges that are listed are fairly standard across the United States although some variations do exist.

-10dB to 25dB = Normal range (Grey)

26dB to 40 dB = Mild hearing loss (purple)

41 dB to 55 dB = Moderate hearing loss (red)

56 dB to 70 dB = Moderately Severe hearing loss (green)

71 dB to 90 dB = Severe hearing loss (yellow)

over 90 dB = Profound hearing loss. (blue)
