In fact, I saw this problem from Zhihu. When I saw this problem, I was shocked. There are always so many people who can think of strange problems…
As we all know, hearing aids are divided into ear back machines and customized machines. Ear back machines are hearing aids worn behind the ears, while customized machines are called inner ear machines, which are hearing aids worn inside the ear canal.
So for this problem, I would like to say that it is OK. But there is a precondition. If you are wearing an ear back machine, you can wear it with two ears on wheels. However, before changing the ear, you need to go to the fitting center to readjust it.
This is because the hearing loss degree of our two ears is different under different frequencies. Just like your eyes, many nearsighted patients actually have different degrees of their eyes. In terms of audiology, the ears are more complex than the eyes. Now, the hearing aids are basically digital hearing aids, which needs to be matched The teacher can only wear it after debugging by analyzing the audiogram, so if you really want to change your ears, it needs to be re debugged.
Secondly, if the hearing aid you wear is a custom-made machine, then you can’t change your ears. The custom-made machine needs to be customized according to your ear canal. Do you dare to guarantee that the ear canals of your two ears are exactly the same? No one can guarantee it. If you wear it forcibly, not only will the hearing loss I said above be inconsistent. If your ear canal is smaller than that hearing aid, then the hearing aid will scream and murmur. If your ear canal is larger than that hearing aid, it will cause ear canal bleeding and infection.
Therefore, I personally suggest that a hearing aid should not be worn with two ears changed. If both ears have hearing loss, it is better to wear a hearing aid with both ears.
