How Loud Is Too Loud? Understanding Decibel Levels

Sound is measured in decibels (dB), and not all noise is created equal. While some sounds are harmless, prolonged exposure to loud noise is one of the leading causes of permanent hearing loss — and it happens more gradually than most people realize.

‍

Most otologists agree that continual exposure to noise at 85 decibels or above puts your hearing at risk. The higher the decibel level, the less time it takes for damage to occur. And once the nerve endings in your inner ear are damaged, that damage is permanent.

The infographic below provides a visual guide to common sounds and their decibel levels, showing how quickly hearing damage can occur at different noise intensities — from a whisper at 30 dB to a jet engine at takeoff reaching 140 dB.

What These Decibel Levels Mean for Your Hearing

Here is a quick reference for how long it takes for noise-induced hearing damage to begin at common decibel levels:

‍

• 85 dB — Beginning of OSHA regulations. Risk begins with prolonged daily exposure.
• 90 dB — Risk of hearing damage after 8 hours. Common sources include lawn mowers and truck traffic.
• 95 dB — Risk of hearing damage after 4 hours. Motorcycles and power saws fall in this range.
• 100 dB — Risk of hearing damage after 2 hours. Chainsaw use and stereo headphones at high volume.
• 105 dB — Risk of hearing damage after 1 hour. Jackhammers and helicopters.
• 110 dB — Risk of hearing damage in 30 minutes. Snowmobile from the driver's seat.
• 115 dB — Risk of hearing damage in 15 minutes. A baby's cry or a stadium football game.
• 120 dB — Risk of hearing damage in 7.5 minutes. Rock concerts and sandblasting.
• 125 dB — Pain threshold. Air raid sirens and firecrackers.
• 140 dB — Immediate danger to hearing. Gunshots and jet engines at takeoff.

Protecting Your Hearing

The good news is that noise-induced hearing loss is entirely preventable. A few simple steps can make a significant difference:

‍

• Wear earplugs or ear protection in loud environments such as concerts, construction sites, or when using power tools.
• Keep the volume on headphones and earbuds at a safe level — a good rule of thumb is no more than 60% of maximum volume.
• Give your ears time to recover after exposure to loud noise.
• Get your hearing checked regularly, especially if you work in a noisy environment.
