What is the criterion for judging elevator noise? How to defend rights when elevator noise disturbs people?

At present, there are three main standards related to elevator noise:

First, the quality standard of the elevator itself, mainly including "Technical Conditions of Elevator" and "Safety Specification for Elevator Manufacture and Installation";

Second, building standards, mainly including "Code for Residential Design" and "Code for Sound Insulation Design of Civil Buildings";

Third, environmental protection standards, mainly including "Acoustic Environmental Quality Standards".

These three standards also have different regulations on the limit of elevator operation decibel: the product standard stipulates that the sound of the main engine room is not higher than 80 decibels, and the sound of the car is not higher than 55 decibels; The architectural design standard stipulates that it shall not be higher than 50 decibels during the day and 40 decibels at night; Environmental protection standards stipulate that it should not be higher than 40 decibels during the day and 30 decibels at night.

Complain about safeguarding rights

When users encounter problems related to elevator noise, they can first ask relevant testing institutions with national qualifications to carry out systematic and scientific testing on elevator noise. After obtaining the legally binding test report, if they find that their elevator noise really exceeds the standard, they can complain to the property management (or developer) or the local department specializing in noise pollution (such as the environmental protection department), and the environmental protection department will deal with the elevator noise that exceeds the standard according to the national environmental protection standards and relevant laws. If the environmental protection department can't solve it, it can only sue the developer through legal channels.

Extended data

Elevator noise is mainly characterized by low-intermediate frequency vibration, and the propagation mode of elevator noise is mainly vibration type, which spreads through solid. Scientific research shows that the low-frequency noise from elevator noise will seriously damage people's internal organs.

Elevator noise mainly comes from the following three sources: first, the low-frequency vibration acoustic energy generated by the traction machine driving operation and the car and counterweight operation in the main engine room propagates along the main load-bearing wall of the structure, causing the disturbance of the wall floor to produce * * * vibration;

Secondly, the friction of the traction equipment urges the elevator car to move up and down, and when the elevator runs at high speed, the friction sound between the traction wheel and the traction rope is generated, sometimes it is transmitted from the steel rope to the car, then to the guide rail, and then to the adjacent wall, which affects the residents;

Furthermore, noise pollution, such as the friction between the guide shoe (guide wheel) and the guide rail, the friction between the rotating parts and the traction rope, the air flow generated by the high-speed operation of the car, etc., will be transmitted to the guide rail and adjacent walls, affecting residents.
