Question 1

What is noise exposure dose?

Accepted Answer

Noise exposure dose measures the cumulative amount of sound energy your ears receive over time. It's expressed as a percentage, where 100% represents the maximum safe daily exposure limit.

Prolonged exposure to loud sounds damages hair cells in the inner ear, causing permanent hearing loss. The louder the sound, the less time it takes to cause damage.

Question 4

What level is considered dangerous?
