Causes of hearing loss, many factors can affect hearing and lead to hearing loss, including long-term exposure to noise, genetic factors, illness, response to certain drugs, trauma, earwax, aging, etc. : Hearing loss caused by aging, noise-induced hearing loss; through hearing tests, we can quickly summarize personal hearing information and find out hearing aid systems that help both hearing loss and improve hearing.
Hearing loss caused by aging
As the age increases to about 50, the auditory cell function deteriorates, especially the treble is most severe. Therefore, it is difficult to hear the ringing of the phone or the ringing of the door, and it is more difficult to keep up with the contents of others during the party. Even under certain conditions, excessive noise can cause serious discomfort.
Noise-induced hearing loss
This is the most modern way to express hearing loss. This is not only the most common occupational disease, but also because modern society is full of various noises and has a greater impact on people.
Noise can also be slow but gradually aggravating the main cause of hearing loss, most commonly in younger ethnic groups, due to prolonged exposure to noisy environments, such as listening to excessively noisy music, resulting in a gradual decline in hearing.
In the early stages of noise-induced hearing loss, patients will find it difficult to listen to high-frequency sounds, and then the midrange will gradually disappear.
Long-term exposure to the volume of 85 decibels may cause hearing damage. For example, if you are in a very loud concert, or listening to MP3 on a large volume, you may find your hearing less sensitive after the music is over. This is because the sensitive hair cells on your hearing organs are temporarily damaged. When you have a rest during a quiet period, they will recover. This is called the temporary threshold shift (TTS), which means that The minimum volume threshold can be heard during the period.
However, if you repeatedly experience a temporary threshold shift (TTS), sensitive hairs and cells on the auditory organs may be permanently damaged, and more severely, will lose their ability to recover. This is called permanent. PTH (permanent threshold shift). Long-term high-volume environments such as concerts or nightclubs, or long-time use of the Walkman are particularly dangerous behaviors. For example, music transmitted through headphones can easily reach 110-120 decibels when people are not aware of it. Suddenly, the loud sounds such as fireworks or firecrackers can also cause damage.
Workers in high volume environments are at high risk of hearing loss, such as workers on construction sites, workers in factories, workers on boarding and landing tracks, or music workers. Workers working on similar tasks should Wear hearing protection for a long time. Another common symptom of hearing impairment is tinnitus, which usually occurs in one ear or both ears, but the inner ear does not respond. In other words, these sounds are almost non-existent.
Hearing loss
There are many people in the world who are affected by different levels and modes of hearing loss. When the hearing loss problem affects life for a long time, it may make people feel lonely or isolated. If the influence is ignored for a long time, it is only a hearing loss of physiological symptoms, which may become a problem of both psychology and physiology. Therefore, it is very important for the hearing loss to find the right solution in real time. The problem of hearing loss is not alone. About 5 million people around the world have hearing loss problems. In other words, in most countries, 6 individuals may have hearing loss problems per 1 individual. After wearing a hearing aid, there is a significant improvement in the hearing of 9 adults. This also means that you don’t have to worry too much about hearing loss. Just look for the right solution and your life will be smooth and confident.
