Be careful, 11 billion young people are at risk of hearing loss!

With the popularization of technology, the sales of smart phones continue to rise. In 2014, more than 10 billion units were sold worldwide.In middle-income and high-income countries, 12-35 year-old teenagers and young people: Nearly half of people use personal audio devices such as MP3 players and smartphones to listen to an unsafe level of loudness and listen for too long .

Another 40% of people are exposed to potentially destructive sound levels in nightclubs, discos and bars.

Once hearing is damaged, it will not be lost and regained!

Regardless of the length of time, exposure to loud sounds can cause the sensory cells of the ear to fatigue, leading to temporary loss of hearing or tinnitus (referring to the sensation of sound in the ear).A person who enjoys a loud music concert will feel his hearing “suffocated” or ringing in his ears when he comes out.With the recovery of sensory cells, hearing is improved.

However, if the volume is particularly loud or frequent contact, or the duration is too long, it can cause permanent damage to sensory cells and other structures, resulting in irreversibleHearing loss.High-frequency sounds (that is, high-pitched sounds) are affected first, and people may not notice it immediately.However, continued exposure can lead to gradual hearing loss, which ultimately affects the understanding of speech and negatively affects the quality of personal life.

9 tips to teach you to protect your hearing

1. Keep the volume low: The daily recommended safe volume level is less than 85 decibels and the duration does not exceed 8 hours.If the listener cannot understand the speech of a person one arm away from him, or if the listener’s ears have pain or tinnitus, the voice may be too loud.

2. Wear earplugs: Use earplugs to protect your hearing in nightclubs, discos, bars, sports venues and other places with a lot of noise.If used correctly, earplugs can reduce noise exposure by 5 to 45 decibels, depending on the type of earplug.

3. Use adapted earphones: in-ear or headphone, preferably noise-canceling earphones, adapted earphones can allow users to clearly hear lower volume sounds.In addition, noise-canceling headphones can reduce background noise, allowing users to hear lower volume sounds.People who frequently use personal audio equipment on trains or airplanes should consider using noise-canceling headphones in these environments.

4. Pay attention to hearing safety level: Set the hearing safety level of personal audio equipment, that is, adjust the volume to a comfortable level that does not exceed 60% of the maximum volume in a quiet environment. This is also a way to keep listening at a low volume.

5. Let the auditory organs take short breaks from time to time: When going to nightclubs, discos, bars, sports events and other noisy places, leave from time to time and let the auditory organs take short breaks to help reduce the total time of exposure to noise.

6. Avoid loud noises: Try to stay away from loudspeakers and other sound sources in places with huge noise.Staying in a quieter place in the premises can also reduce exposure to noise.

7. Limit the time you spend on personal audio devices every day: Although lowering the volume can play an important role, limiting the time you use personal audio devices to no more than one hour per day is very helpful to reduce exposure to noise.

8. Pay attention to signs of hearing loss: such as tinnitus, difficulty hearing high tones such as the doorbell, telephone bell, and alarm bell, inability to hear other people’s speech (especially on the phone), or in noisy environments such as restaurants or other social occasions People who cannot keep up with other people’s conversations and suspect that they are hearing impaired should seek the help of a hearing care professional.

9. Parents need to play an active role: educate their children to protect their hearing and supervise their exposure to loud noises; parents also need to be role models for their children in protecting hearing.Encourage regular hearing checks for high-risk groups such as teenagers and young adults.
