Everyday scenarios like attending concerts, live sporting events, or working in noisy environments can expose our hearing to noise levels that, in the moment, seem harmless. However, over time, these seemingly harmless sounds can cause permanent hearing damage.

That's where decibel meter apps come in. They can effectively transform your smartphone device into a professional-grade sound level meter, tracking and identifying hazardous environmental noises, allowing you to proactively take measures to protect your hearing and enjoy life without the looming threat of hearing impairement.

What is a Decibel Meter App?

A decibel meter, also known as a sound level meter or SPL meter (sound pressure level), is a device that measures noise levels and displays the sound's intensity in decibels (dB).

Nowadays, this technology is readily accessible as a downloadable app from your smartphone, using the device's built-in microphone. This technology is a practical and user-friendly tool for raising awareness of sound levels in your environment and taking appropriate measures to safeguard your hearing health.

How Loud is Too Loud for Your Hearing Health?

The loudness level considered "too loud" for your hearing health can vary depending on several factors, including the duration of exposure and individual sensitivity to sound. 

Here's a breakdown of how loud is too loud for your hearing health:

Decibel Chart

Decibel Level (dB) Sound Example Potential Impact on Hearing
140 dB Fireworks, gunshot Extremely high risk of immediate damage with short exposure.
130 dB Jet take-off (100 meters) Very high risk of immediate damage with short exposure.
120 dB Ambulance sirens, thunder High risk of immediate damage with short exposure.
110 dB Chainsaw (close), live rock concert High risk of immediate damage with short exposure.
90 dB Lawnmower Risk of hearing damage with prolonged exposure.
85 dB Heavy traffic Risk of damage with extended exposure.
70 dB Busy traffic Prolonged exposure may risk hearing damage.
60 dB Normal conversation Safe, common social environments.
50 dB Rainfall Safe, moderate noise, no risk.
40 dB Refrigerator humming Safe, typical home noise.
30 dB Quiet library Safe, comfortable, conversational level.
20 dB Rustling leaves Safe, normal background noise.
10 dB Whisper Safe, virtually no risk.

Noise-induced hearing damage is cumulative, meaning that the more time you expose your ears to noisy environments, the greater the risk to your hearing. To protect your hearing, consider using a decibel meter to detect loud settings and use hearing protection, such as earplugs or earmuffs.

Take a look at the best decibel meter apps.
