More and more people are using Bluetooth Earbuds to listen to music, watch TV or watch movies. With so many sounds in our ears, can't anything go wrong? To this end, lafer a Bluetooth headset manufacturer, is going to give you an idea of noise-induced hearing loss.
Noise-induced hearing loss is caused by high intensity noise that damages the inner ear. Prolonged exposure to sounds louder than 85 decibels can lead to permanent hearing loss. For occupational safety and health research, countries recommend that daily noise levels should be below 85 decibels, allowing workers to be exposed to 85 decibels for eight hours. For every three decibels above 85 decibels, the time it takes to hear a sound deemed "safe" is halved. So experts advise listeners to listen for four hours at 88 decibels, two hours at 91 decibels, one hour at 94 decibels, and so on.
In fact, safe hearing levels are based on older studies. Now research shows that even limited noise exposure can cause permanent damage
