# What is the difference between a deafening sound and a loud sound?

Jul 19, 2017

A deafening sound is a noise which is so high in amplitude and frequency which can make you deaf, whereas a loud sound can seem unpleasant but it does not usually cause long time effects.

#### Explanation:

Sound up to 80 decibels can be very loud.

• at $91$ decibels, your ears can tolerate up to two hours of exposure.
• at $100$ decibels, damage can occur with $15$ minutes of exposure.
• at $112$ decibels, damage can occur with only one minute of exposure.
• at $140$ decibels, immediate nerve damage can occur.

The above was taken from here.

So these are the levels of a deafening sound.
