Deafness By Sound
Deafness is a disability that affects the way you hear the world around you. Deafness can make life harder for you to live. Deafness can be very mild to very extreme.
What is Deafness?
How is Deafness caused?
Deafness can be caused in many ways like illness, injury or genetically. The most common way of getting Deafness is by sound, listening to music too loud or being near loud things can cause Deafness by sound.
How does sound lead to Deafness?
Thank you for watching my Prezi
Every day we experience sounds in the environment. Like sounds from your TV to the traffic on roads, usually we hear these sounds at safe levels that don't affect our hearing. Although, when we are exposed to sounds that are too loud or loud sounds that last a long time sensitive parts in our ear can be damaged.

Whisper Quiet Library 30dB
Normal conversation 60-65dB
Telephone dial tone 80dB
City Traffic (inside car) 85dB
Train whistle, Truck Traffic 90dB
Jackhammer 95dB

Decibel chart from GALEN CAROL AUDIO
Depending on the decibel is how sound can lead to deafness. The weakest sound heard is 0dB (decibels) as sound gets louder the level of dB rises. City traffic in your car is 85dB. When sound gets up to 90-95dB you will lose your hearing for a different amount of time depending on the duration of the sound

The reason I chose my question...
The reason I chose Deafness is because I wanted to choose something that I didn't know much about and was interested to learn more about it.
