120 decibels is the threshold of hearing for humans.

Explanation:

Any sound louder than 120 decibels will force your ears to adapt to the sound and might result in hearing loss especially if you are exposed to it for a long period of time. That is the reason why people who operate loud machinery must always wear sound proof ear muffs to prevent deafness.
