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, Innoson, 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 to the tiny ribbons between hair cells, the hearing cells in our ears. In other words, the deafness and tinnitus we experience after a large concert or a noisy gathering due to loud and noisy sounds is not just temporary hearing loss. The damage becomes apparent after 10 or 20 years, so hearing loss is more pronounced in old age.
The loss of hearing is gradual. First, it is often high-frequency hearing that is damaged, with little or no detectable impact on our daily lives. However, as the damage continues to exist, hearing further appears other frequency decline, which will lead to our daily referred to as "deafness", so people's life, learning will be seriously affected.
Here, Innoson recommends five tips to protect your hearing when using a Bluetooth Earbuds:
1. Turn down the volume - Set the volume limit on the device so that you can listen at no more than 70% of the maximum volume.
2. Turn it off -- Hearing at high decibels for long periods of time can be particularly damaging. You can use the 60/60 rule, which is to listen at 60% volume for 60 minutes and then rest for 30 minutes or more to let the ears rest and recover.
3. Choose a headset -- plug in headphones are 9 decibels louder than the headset. If you're listening to music at 91 decibels, the plug - in headphones will cut your safe listening time from two hours to 15 minutes.
4. Choose noise-canceling Bluetooth Earbuds -- this is especially important if you prefer listening to devices in noisy environments such as busy city streets, subway buses, etc. If you are not aware of this, you tend to overcome the ambient noise by turning up the volume of your headphones.
5. About bass -- If you are a bass fan who is looking for strong vibrations and "headbutt" effects of music, use the equalizer on your device to turn up the bass. Even if you turn down the volume, you will achieve satisfactory results.
In short, the use of Bluetooth Earbuds must pay attention to reduce the volume, soft is appropriate, do not listen for a long time.
