Boss Wang opened a mechanical design and assembly factory in Tonglu. He reflected that the noise produced upstairs had a great impact on him, and the master workers could not work with peace of mind, and he could not design equipment here.
Boss Wang opened a mechanical design and assembly factory in Hangzhou Tonglu Alpha Intelligent Manufacturing Industrial Park, the plant is located on the first floor, and the second floor of the interview constantly emits frequent vibrations and sounds. Boss Wang said that when they moved into the factory in May, the noise coming from upstairs was even louder than this, and they did mechanical design and assembly were very meticulous work, and they needed to calm down.
"There are 6 to 8 punch-like devices on it, and the noise frequency is 53 times per minute, which is very irritable for the long-term (damage) of hearing, because it is continuously vibrating, 53 times per minute." ”
Boss Wang also built an overhead floor in this factory, closer to the floor slab on the second floor, he said that he had planned to make an office for himself and usually design machinery.
The office has been empty due to noise issues. He had previously measured it with the decibel testing software of his mobile phone, and the noise during the day had exceeded 75 decibels.
"The environmental protection department believes that there is no law enforcement basis for self-testing, so we have done the test through a third-party agency, and the test result is 73.8 (decibel), which is completely beyond the national regulations of the industrial plant below 65 decibels." ”
Boss Wang found a copy of the "Sound Environment Quality Standard" and a "Environmental Noise Emission Standard for Industrial Enterprise Manufacturers" on the official website of the Ministry of Ecology and Environment, according to the instructions in these two standards, his plant location belongs to the 3 types of environmental functional areas, that is, the area with industrial production, warehousing and logistics as the main function, and the environmental noise limit of the 3 types of environmental functional areas cannot exceed 65 decibels during the day and 55 decibels at night.
The third-party testing agency measured a junction of 73.8 decibels, which is beyond the scope specified in these two standards. After he provided the test report to the local environmental protection department, the environmental protection department came to the door and asked for rectification on the second floor. During the interview, Boss Wang took the decibel meter and tested it here in the overhead floor of his factory, and the sound coming from upstairs was about 60 decibels.
"He may only have one device on now, and if he drives more, he won't be able to stay down there." ”
On the second floor is a non-woven fabric production plant, and the person in charge is also surnamed Wang. He said that the sound was made by the non-woven cutting machine in the factory, and it was true that only one equipment was opened in production just now. The sound size of their upstairs feels fine, but it can be noisy downstairs, and he is making corrections during this time.
"The environmental protection department asked me to limit production, a few machines stopped it, and then I moved the machine to this side, and there was a 2 cm thick rubber pad underneath, I ran several times, went down to hear the sound, how the effect was, he was not there (: I am not here, but my workers are in ah, there are people on Friday) I knocked on the door for half a day, his car is in, including yesterday, I still lie down to look, no one (: then did you notify the environmental protection department to check it again?) I didn't notify, why, I didn't hear the sound, didn't hear the effect, I didn't dare to notify them (: Are you afraid and not pass?). I'm afraid and I don't meet the standards, don't I? ”
The boss on the first floor Wang believes that the effect of these two centimeters of rubber pads under the machine is not ideal.
Boss Wang on the second floor responded that he had another plan, before he purchased several air pressure shock absorber pads, the top with a steel plate to combine the shock absorber pads, and then put the production machine on top, so that the vibration and noise should be much smaller, just everyone is in, he put the shock absorber pads on, opened the machine, together to the first floor to listen to it, the sound is basically not heard.
"Then there is no sound now." ”
"That's how it will be changed now." We are saying hello, hello, hello, we are definitely good neighbors, everyone should be considerate of each other, I have to be able to sit in this office, I actually mean this, I have no other appeal. ”
