The higher the decibel measure, the higher is the loudness in a place.
Sounds from the range of 0 dB to 60 dB are fine to the ears.
From 60 dB to 85 dB, humans start being annoyed by the sounds.
Then, starting from 85 dB, the sound is too loud and starts damaging our ears.
Therefore, after 85 dB humans can experience ear damage.
