Listen Smart – Safely Handling the Power of Sound
- Hearing loss can be gradual, or instantaneous
- Listening smart, is listening in a way that enriches you but cannot hurt you
- Sound is measured in decibels, or strength of sound
- Hearing damage will start at 90 decibels, if in that environment for more than 8 hours
- You should not listen to something at 100 decibels for more than 2 hours
- Sound above 120 decibels should be avoided completely
- Pain in the ears will begin at 125 decibels
- A concert, can expose you to 140 decibels of sound, about the same amount as a jet airplane’s takeoff
- Long term exposure to loud sound can permanently damage your hearing abilities

- The best medicine is prevention (earplugs, standing further away, take a break, avoid stimulants
