Nowadays, elevator noise is indeed a big problem that plagues many residents. In fact, this is due to the fact that many companies have failed to meet the requirements of the installation quality during the elevator installation process, or have not installed in accordance with the rules and regulations, etc., and have not dealt with various details. Then, let’s take a look today. The noise during elevator installation What are the provisions of the standard:

Conventional standard

At present, there are mainly three types of standards related to elevator noise: one is the quality standard of the elevator itself, which mainly includes "Elevator Technical Conditions", "Safety Code for Elevator Manufacturing and Installation", etc.; the other is building standards, mainly including "Code for Residential Design" ", "Civil Building Design Sound Insulation Code"; the third is environmental protection standards, mainly including "Sound Environmental Quality Standards" and so on. These three types of standards also have different regulations on the decibel limit of elevator operation: product standards stipulate that the sound of the main engine room should not be higher than 80 decibels, and the sound of the car should not be higher than 55 decibels; the architectural design standards stipulate that the It shall not be higher than 40 decibels at night; the environmental protection standard stipulates that it shall not be higher than 40 decibels during the day and 30 decibels at night.

Regulatory standards

On October 1, 2008, the country officially promulgated the "Social Life Environment Noise Emission Standard" (22337-2008) and "Acoustic Environmental Quality Standard" (GB3096-2008) and other new national standards. Establish clear standards for the emission of indoor solid noise (low-frequency noise). Prior to this, elevator noise was indeed a headache. Because according to the original standard, the elevator noise generally does not exceed the standard. No matter how the victim complains, the competent government department cannot rely on it, so it is more difficult to deal with it. Now that there are laws to follow, victims can lodge complaints with government departments, and they will be resolved satisfactorily. The competent government departments are the special equipment management unit of the Technical Supervision Bureau and the petition and complaint unit of the Environmental Protection Bureau. The special equipment management unit of the Technical Supervision Bureau is responsible for the issuance of elevator operation licenses. If they fail to meet the national standards, they will order the relevant units to make corrections. If they do not make corrections, they will revoke the elevator operation licenses in accordance with laws and regulations; Units, of course, will enforce it in accordance with the law.

The highest applicable standards The state has made relevant regulations on elevator noise standards "According to the latest relevant elevator noise standards established 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. Elevators affected by noise also include the mainstream "frequency-modulated and voltage-regulated elevators" and "machine-roomless elevators" currently mainstream in the market and the "permanent magnet synchronous elevators" with the lowest noise. By taking appropriate measures to reduce vibration, sound insulation, and noise reduction, and reduce and block the influence of low-frequency vibration of the elevator through a declining design, the sound level of the elevator noise A in the residential room can be less than 35dB.
