The damage to your ear occurs with the louder sound and exposure of the volume to your ears. Usually, the sound is measured in decibel units, like the height is measured in feet or inches. Because sensitive ear lobes and eardrums can’t hear all frequencies, or pitches of sound, the decibel (dB) can be used to explain the sound based on what human ears can hear.
The safe levels of Sound are at or below 70 dB. The sounds which are above 85dB are most likely to damage your ears over time.
There is a greater risk for hearing damage if anyone is continuously exposed to noise levels above 85 dB over a long period of time.
That’s the sole reason why DJ operators and other staff at concerts wear earplugs to avoid damage while they’re on job.
The kids today use devices which have noise levels much higher than 90dB. The music played through the earphones at the highest volumes 95-110 dB.
Distance from the source
Distance plays an important role as the sound gets louder as you move closer to the sound origin and lighter as you move away from the source. If you are a few meters away from the sound, the risk of damage to your hearing is much lighter. For instance at concerts, for instance, sitting far from the speakers will reduce your risk of damage.
Time
Time also plays an important role in the amount of volume. If you are exposed to loud sounds on a routine basis, your risk for hearing damage increases over time. Even a single but big long-lasting loud event can cause damage to your ears. Sounds which are below 70 dB are usually considered safe and impact for better hearing, even if they last a long time.
Sound levels are more likely to damage your hearing if they are:
- 85 dBA - Few hours.
- 100 dBA - 15 minutes.
- 110 dBA – immediate or at least
2 minutes
