If you know you're going to be around loud sounds for more than a few minutes, think about wearing protection
- Earplugs. Usually made of foam or rubber, they go in your ear canal and can reduce noise by 15 to 30 decibels. You can buy them off-the-shelf or have them custom-made to fit you. Some earplugs lower noise levels evenly across all frequencies. They’re useful for people who need to make sound quieter but undistorted, such as musicians.
- Earmuffs. These fit completely over your ears and reduce sounds by about 15 to 30 decibels. They have to fit tightly over both ears to block sound.
You can also wear earplugs and earmuffs together for even greater protection.
