🔊 What Is Noise-Induced Hearing Loss (NIHL)?
Loud noises cause something known as Noise-Induced Hearing Loss (NIHL). These sounds can be brief, like those from gunfire, or prolonged, like concert music. You’re susceptible due to three main factors:
- The volume of the noise
- Your proximity to the noise
- The duration of exposure
💥 Impulse Sound
Impulse or impact noise—like fireworks or gunfire—can cause immediate, irreversible hearing loss. Measured in dB peak (dBP), any impulse noise above 140 dBP can permanently damage your ears.
📊 Dangerous and Safe Noise Levels
Severe impulse noise (not safe):
• 150 dBP = Shotgun, firecracker, pyrotechnics at 3 ft
• 140 dBP = Firearms
Severe steady noise (not safe):
• 130 dBA = Jackhammer
• 120 dBA = Airplane takeoff, siren, pneumatic drill
Harmful (protection required):
• 112 dBA = Chainsaw, concerts, audio players
• 106 dBA = Snow blower, gas leaf blower
• 100 dBA = Tractor, headphones
• 94 dBA = Blender, food processor, hair dryer
Very Loud (limit exposure):
• 91 dBA = Subway, gas mower, motorcycles
Moderate (generally safe):
• 70 dBA = Group conversation, alarm clock
• 60 dBA = Normal conversation, dishwasher
• 50 dBA = Rainfall
• 40 dBA = Quiet room
Faint (always safe):
• 30 dBA = Whisper, quiet library
• 150 dBP = Shotgun, firecracker, pyrotechnics at 3 ft
• 140 dBP = Firearms

🛡️ How to Keep Your Hearing Safe
- Use proper hearing protection:
- Earplugs: Fit inside the ear canal. Can reduce sound by 15–30 dB.
- Earmuffs: Cover the entire ear, fitting snugly for effective protection.
- Both: Use both earplugs and earmuffs for extreme sound levels (above 105 dB or 140 dBP).
- Limit exposure to loud environments: Step away when possible. Cover your ears during emergency sirens or loud events.
- Turn down the volume:
- Keep personal devices at 50% volume or less.
- WHO suggests below 80 dB for adults and below 75 dB for kids during a 40-hour week.
- Ask for volume adjustments in cinemas or public places if too loud.
- Be an advocate for quiet: Raise awareness in noisy venues like theaters, gyms, clubs, and amusement parks. Encourage sound control.
❗ Final Thoughts
Don’t believe you can “tune it out” or that your ears are “tough.” Noise-induced hearing loss is often gradual and painless—but it’s permanent. Damaged hair cells do not recover.
- Use hearing protection consistently
- Choose quieter appliances, power tools, and toys
- Educate family and coworkers about safe sound levels
- Schedule regular hearing tests to monitor your auditory health
Your hearing health is worth protecting—every day.
