Noise hazards and precautions

Hearing is one of the most precious instincts we each have. If we lose it, it will be difficult for us to live regardless of our working hours or after work.

If the frequency of sound or noise is too high, they will cause our hearing to be permanently damaged. The degree of noise damage depends on how high the frequency of noise is and how long you are exposed to the noise environment. Because of the harm of noise to each of us, the daily damage is so slight that we are not aware of it, but over time, we can perceive the permanent change of noise to our hearing. Our only way to prevent noise hazards is to minimize our exposure time in noisy environments.

What harm does noise do to us? ?

The auditory nerve cells in our ears can be killed by excessively high noise. The dead auditory nerve cells will be replaced by scar tissue that does not respond to sound. The damage of noise to our hearing is not painful, but the damage is permanent. Noise damage to our hearing is incurable. Some medical assistance can only partially restore our hearing, but it cannot be restored to normal levels.

The auditory nerve cells killed by noise are mainly the auditory nerve cells in our ears that can transmit high-frequency sounds. The result of noise damage is our loss of ability to respond to high frequency sounds. If your hearing is weakened, you cannot use hearing to judge what is going on around you. You will miss a warning or a solicitation, or misunderstand some important information.

People with prolonged exposure to noise can also suffer from tinnitus, accompanied by hearing loss. Having tinnitus is painful, especially when you are about to fall asleep.

You may think "If I detect noise that damages my hearing, I will use whatever methods to treat noise damage." Unfortunately, you cannot be aware of it. Noise grows slowly and painlessly on you until you feel it is quiet and you realize that you have already suffered from noise.

The effective solution to noise hazards?

There are many measures that can reduce people's exposure time in a noisy environment. These measures are as follows:

1, eliminate the source of noise

Measures must be taken in mechanical and process design to control high-frequency noise, such as installing anti-vibration devices in the vibration part of the mechanical device.

2. Keep noise away from employees

Keep noise-generating machinery in the soundproof room, or set up soundproof walls between the noise-generating machine and the staff.
