The compressed air being used, the spindle rotating at high speed, the cutting tools... This is our daily working environment. It seems that except for this harsh sound, nothing else can be heard.
Perhaps it was only when the power went out that we discovered that there were still a few sparrows in the small trees outside the workshop.
Some masters with longer working experience cannot hear the birds chirping. He may be 60 years old now, he may be 40 years old, or he may be your current age.
He would put his cell phone next to his pillow every day before going to bed because if he placed it too far away, he would not be able to hear the morning alarm;
He may be hit by a passing bicycle while buying breakfast because he cannot hear the passing bicycle bell;
He may talk to you very loudly because he cannot hear what you are saying clearly. In his perception, only in this way can you hear what he is saying;
When making a phone call on a vehicle, he must turn on the speakerphone and put the speaker to his ear, so that he can hear the voice on the other end of the phone;
If you happen to sit next to him in a restaurant, you can even hear whose song is playing in his headphones.

He may continue to live like this after hearing damage, or it may be worse, because hearing damage cannot be repaired. If he were 40 years old now, he might have to live like this for the rest of his life.
This "he" may be your colleague, your friend, or if more unfortunate, it may be yourself.
When we see the gray weather outside, we will consider whether to wear a mask and go out; but when faced with the roar of machines in the workshop, we choose to ignore it.

My ears started ringing as soon as I got to work, I forgot where I put the USB flash drive I saw just now, and I lost my appetite when I was eating. Even if you don't do anything, you will feel that your body is too tired and want to take time off to rest.
Things that could be done in 30 minutes before are now not finished in 2 hours. I often get distracted during meetings and almost fall asleep on the conference table. I always feel that the sound of the TV is not loud enough...
What can we do when our hearing is affected by excessive noise that affects our work and life?
01 Be aware of noise. If you are exposed to loud noise (>85dB) for a long time, your hearing will be damaged if it is not protected. Hearing damage is a disease, a permanent disease. This disease will accompany you for a lifetime and cannot be recovered or cured.
02 Understand the source of noise. Indoor punch machines, lathes, machining centers and other machines will produce a lot of noise during normal operation. Grinders, cutting machines, vibration grinders, air compressors and other machines will also produce a lot of noise when in use. Operators are required to wear hearing protection when these machines are in operation.
03 Master the correct use of hearing protection devices. Common ones include earmuffs and earplugs, both of which can have a very good sound isolation effect, provided you use them correctly.
04 Choose the hearing protection device that suits you. When considering the sound insulation effect, you also need to consider safety, such as forklift drivers in the workshop, etc.
05 Check the price of earplugs.

So, do you wear earplugs at work?
