To understand the world, besides looking directly at the eyes, listening to the ears is another way.

But we often cause deafness and hearing loss for a variety of reasons, so that we can not listen to the sound of this beautiful world.

There are many reasons for deafness, such as noise, genetics, ototoxic drugs, etc. Unfortunately, suffering from deafness can be said to be quite painful.

Under normal circumstances, the deafness that we are familiar with is inaudible. If you can’t hear what others say, you often think that talking to people who are deaf is very loud. In fact, not all deafness is like this. Have you ever encountered this? In the case, talking to a deaf patient, you are afraid that he can increase the volume if he can’t hear it. As a result, he accuses you of being so noisy, or you and a deaf patient walked on the road and walked through a stall where people were sipping, they The voice of your voice is normal, not light or loud, but the deaf patients next to you complain that it is too noisy.

So what is the reason that they are obviously suffering from deafness but still noisy?

In fact, deafness is still a noisy one is a relatively common phenomenon in deafness: re-vibration.

Re-vibration phenomenon, we can call it a reverberation, for a simple example, the voice we generally speak is60Decibel if we increase10What is the decibel sound that is heard in the ear of the hearing? is not it70Decibel, but it is not for patients with rejuvenation, although you only increase10The volume of the decibels, but in their ears, what may be heard is20decibel,30Decibel, even60decibel.

I also said that it is more common to reproduce the phenomenon in deafness. There are statistics, there are76%Patients with sensorineural deafness suffer from rejuvenation, so for these deaf patients, when communicating, the slowness of speaking is more effective than speaking loudly.
