Significance of tinnitus if you need to be careful about "earphones on the train" in your ears | PRESIDENT Online (President Online)

Don't you think that your ears get far away in your 70s and 80s?"Due to the changes in living environment and customs, the number of people who are young, not only for the elderly," said Masafumi Nakagawa, an otolaryngologist.

Hearing begins to peak at the age of 20.In the forties, signs of lighter hearing begin to appear, and the number of people who feel inconvenienced in everyday conversation in their 60s has begun to increase.25 % of the age of 65 and 50 % for those 75 years old or older have data that "hearing loss requires hearing aids."Even in the 50s and 60s who work in the active duty, it is highly likely that hearing loss is progressing if they often ask people back or louder.

The main causes of hearing loss are aging, such as hyperglycemia, hypertension, and arteriosclerosis, but another major cause is "there is an internal ear disorder due to noise. When you hear a loud noise, it is damaged inside the ear.I will receive it, "says Nakagawa.

Have you ever listened to loud music at concerts, etc., and have had a lot of tinnitus on your way home or the next morning?This is called "rock hearing loss (acute acoustic traumatic hearing loss)" and temporarily occurring with endomeric disorders.In the modern age, the sound is overflowing in the living environment and the ears are not resting.

"There is a considerable difference between the total amount and size of the sound that the human beings in the days when there were no television nor radio had heard on the day, and the present age.The upper limit of the sound is about 59 minutes for 90 dibel. For example, the inside of the Shinkansen is in a sound environment of about 80 dibel, so just on a business trip to the Shinkansen will exceed the upper limit of the day. "

Pachinko, karaoke, mahjong, and other people's voices, such as the voices of nearby people, are a factor in a loud space that is difficult to hear, which accelerates the aging of the ears, and walking and running for maintaining health, as along the national highway.The noise is so intense when performed in a place with a lot of traffic, so the ears are loaded, and it is full of hearing loss factors.
