Even mild hearing loss makes it very hard to hear normal conversations. According to the NIOSH, just 30 minutes of exposure to sound louder than 97 decibels -- about the same volume as a handheld electric drill -- can permanently damage your hearing. Don't take a chance! Earplugs are an important, inexpensive safety item.
But earplugs won't let me hear my car or the cars around me!
Earplugs still allow you to hear, just at a reduced volume. Earplugs can actually make some of the more subtle sounds easier to hear! By keeping the loud noises at a level your ears can handle, quieter noises are able to come through. With earplugs, you can still hear and identify noises such as a cracked header, knocking rod, or worn wheel bearing. Without earplugs, all you hear is a dull roar -- followed by a sharp ringing sound.
