Protecting Your Hearing

Raising Awareness About Excessive Noise


What is sound

What issound?

  • Vibrations or waves that move through the air or water. Caused by molecules bumping

    into each other.

  • The faster a wave vibrates, the higher the sound; slower waves produce low sound

  • Our voice produces sound because of vocal cords in our throat that vibrate when air is forced through them.


The human ear

The HumanEar

The ear is divided

into 3 parts:

-The outer ear or pinna,

funnels sound waves into the ear canal, which will lead to the eardrum. This is a membrane that stretches across the entrance to the middle ear.

-The middle ear has three tiny bones, the hammer, the anvil, and the stirrup. This is where waves become amplified.

Inside the inner ear is a coiled tube called the cochlea. It is filled with fluid, special “hair cells,” and nerve endings. It signals the brain, which lets you know what sound you heard. You will also find the semicircular canals which help control balance

Sensory hearing loss

Sensory Hearing Loss

Caused by damage to the tiny hair cells in the cochlea. It is permanent.

  • Most common causes:

    • Aging

    • Loud noises. This damage is

      preventable!!


Noise and its effect on hearing

Noise and Its Effect on Hearing

  • Sounds are measured in decibels (dB). Very high levels cause damage to your hearing

  • Hearing loss due to loud noises is common in

    children, adolescents,

    and adults


Noise levels and time to permanent hearing loss

Noise Levels and Time to Permanent Hearing loss


Examples of sound levels in our environment

Examples of Sound Levels in Our Environment

  • Listening to music on earphones at volume level 5, the sound reaches a level of 100 dB, loud enough to cause permanent damage after just 15 minutes per day!
