Noise is everywhere. It does damage to our hearing when we don’t come to realize if it comes to a dangerous level.
NIOSH and CDC release the app that makes noise level test easy for every smart phone owner.
Keep sensitive to the sound level you are exposed to. If it comes to a dangerous level, for example, higher than 85 dB(A), you should use hearing protection products like earplugs, earmuffs etc..
You can download the app published by NIOSH.
Keep safe and enjoy your life.
