Unconsciously increasing the volume of headphones in noisy environments such as public transportation, and wearing headphones for extended periods of time due to addiction to videos and games These inappropriate habits of wearing headphones are quietly damaging our hearing. Now let's learn how to protect our ears!

Close, long-term, and high-intensity noise exposure not only damages our cochlear hair cells, but also affects other auditory conduction structures, leading to tinnitus, hearing loss, and so on. However, the number of cochlear hair cells is fixed and cannot regenerate. Once the cells die, hearing damage will be permanent and irreversible.

No matter what type of earphones you wear, you should remember the "60-60-60" principle, which means that the volume should not exceed 60% of the total volume, and the listening time should not exceed 60 minutes each time. It is best to not exceed 60 decibels of external sound. Choose and use headphones to protect our hearing while enjoying life.

Different headphones have different transmission modes and functions. As mentioned earlier, wearing headphones carries the risk of hearing damage. Therefore, choosing and wearing headphones correctly can greatly protect our ears.

1. Earmuff type earphones:Earmuff earphones are more recommended for daily use. On the one hand, they can cover the earlobe to prevent noise from entering, and on the other hand, the sound emitted from the earphones is farther away from the eardrum and less irritating to the cochlea, making them safer.

2. In ear headphones:Especially with earplugs, a closed space is formed within the ear canal, which can easily cause ear inflammation, causing itching, dampness, pain, etc. In addition, due to the more concentrated transmission of sound to the eardrum, the stimulation of cochlear hair cells will also be greater.

3. Noise reduction earphones:It is not recommended to wear headphones in noisy environments such as public transportation or noisy public places, as we will inevitably increase the volume and increase the risk of hearing damage. At this point, it is recommended to use noise reducing headphones, which can reduce noise.

Currently, noise reduction earphones are divided into active and passive noise reduction earphones. Active noise reduction headphones refer to the use of a noise reduction system to generate reverse sound waves that are equal to external noise, neutralizing the noise and achieving noise reduction effects. Passive noise reduction headphones mainly surround the ears to form a closed space, or use soundproofing materials such as silicone earplugs to block external noise. Visible noise reduction earphones can help us hear sound clearly at a lower volume, providing ear protection.

4. Bone guided earphones:This is a headphone that has been popular among fitness enthusiasts in recent years. Bone conduction sound may sound magical, but in fact, sound waves do not pass through the ear canal and pass through the skull to the cochlea and auditory nerves. Therefore, like other earphones, it still stimulates the cochlea. Its biggest advantage is that while hearing the sound of the earphones through bone conduction, the ears are still receiving external sounds. Therefore, outdoor exercise can avoid accidents caused by not hearing the warning sound, and is suitable for those in the middle ear There are infections such as swelling, pain, and pus in the ear canal.

Use headphones for no more than 40 hours per week and try to keep the volume within 80 decibels.

Wear earplugs to isolate noise in noisy places such as dance halls, bars, and sports venues.

Use noise reducing headphones in noisy environments such as public transportation to reduce and increase volume.

Monitor the time and volume range of using headphones.

Restrict the daily use of personal audio.

Limit the activity time in noisy places and maintain a distance from loud sound sources, such as going to quiet places to give your ears a brief rest.

If exposed to noise for a long time, regular hearing tests should be conducted to detect hearing damage as soon as possible.
