Why can deaf still disrelish noisy?

In addition to seeing the world directly with your eyes, listening with your ears is another way.

But we often suffer from deafness and hearing loss for a variety of reasons, which make us unable to listen to the voice of this beautiful world.

There are many reasons that can cause deafness, such as noise, genetics, ototoxic drugs and so on. Unfortunately, suffering from deafness can be quite painful.

In general, we are familiar with deafness because we can’t hear clearly and can’t hear what others say. We often think that it’s necessary to speak loudly with deaf people. In fact, not all deafness is like this. Have you ever met such a situation when talking with a deaf patient, and you are afraid that he can improve the volume even if he can’t hear it? As a result, he accused you of being so noisy , or you walk along a stall with a deaf patient, where people are shouting. You think their voices are normal, not light or loud, but the deaf patient beside you complains that they are too noisy.

So what’s the cause of their deafness?

Actually, deafness is a common phenomenon among deafness: rejuvenation.

We have a phenomenon called reverberation. For example, we usually speak at 60 decibels. If we increase the volume by 10 decibels, how many decibels can we hear in the ears of people with normal hearing? Is it 70 decibels? But it’s not true for patients with rejuvenation. Although you only increase the volume by 10 decibels, they may hear 20 decibels, 30 decibels or even 60 decibels in their ears.

Before that, it was also said that rejuvenation is common in deafness. According to statistics, 76% of patients with sensorineural deafness suffer from rejuvenation. Therefore, for these deaf patients, speaking slowly is more effective than speaking loudly when communicating.
