What are the standards related to elevator noise

At present, there are three types of standards related to elevator noise: one is the quality standard of the elevator itself, which mainly includes elevator technical conditions, elevator manufacturing and installation safety specifications, etc .; the other is construction standards, which mainly include residential design specifications, civil building design partitions, etc. Acoustic specifications; Third, environmental standards, including acoustic environmental quality standards. These three types of standards also have different regulations on the elevator decibel limit: product standards stipulate that the sound of the main engine room must not be higher than 80 decibels, and the sound of the car must not be higher than 55 decibels; the architectural design standards stipulate that the noise must not be higher than 50 decibels during the day, It should not be higher than 40 decibels at night; environmental protection standards stipulate that it cannot be higher than 40 decibels during the day and 30 decibels at night.

Regulatory standards

The state has officially promulgated new standards. Set clear standards for indoor solid noise (low-frequency noise) emissions. Prior to this, elevator noise was indeed a headache. Because according to the original standard, the noise of the elevator generally does not exceed the standard. Regardless of the complaint of the victim, the competent government department cannot rely on it, so it is more difficult to handle. There are laws to follow, and victims can lodge a complaint with a government department, which will surely be resolved satisfactorily. The competent government departments are: the special equipment management unit of the Technical Supervision Bureau and the complaint unit of the Environmental Protection Bureau. The special equipment management unit of the Technical Supervision Bureau is responsible for the issuing of elevator operation permits. If they fail to meet national standards, they will order the relevant units to make corrections. If they do not make corrections, they will revoke the elevator operation license according to laws and regulations; Units, of course, will be implemented according to law.

The highest applicable standard The state has made relevant regulations on elevator noise standards. "According to the latest elevator noise standards formulated in 2003, the elevator noise value measured in the elevator machine room should be ≤80 decibels." At present, most domestic brands of elevator noise can be controlled. Within 60-75 decibels, it can meet the requirements of national standards. The elevators affected by noise also include the mainstream FM elevators in the current market, machine-room-less elevators, and the permanent-magnet synchronous elevators with the lowest noise. By adopting appropriate measures to reduce vibration, noise, and noise, and to reduce and block the impact of low-frequency vibration of the elevator through a diminishing design, the noise level of the indoor elevator's noise A can be ≤35dB.
