Elevator sound insulation management, elevator room noise treatment

Elevator noise is a common noise in residential areas, and the noise value of the elevator is around decibels when it is running. Seriously exceeding the national standard, it has a bad impact on the daily life of the surrounding residents. The elevator sound insulation treatment plan can effectively solve the elevator noise problem. After treatment, it is lower than 45 decibels during the day and no more than 35 decibels at night. Comply with the relevant national noise emission standards and achieve satisfactory results for residents.

I. Background of elevator sound insulation management project

When the elevator in a community in Hangzhou is running normally, the indoor noise of the surrounding residents is 50 decibels. It exceeds the relevant national regulations and has a serious impact on the daily life of residents.

II. Elevator sound insulation management plan

1. Noise source

The mechanical noise caused by the Traction Machine in the elevator machine room is mostly medium and low frequency noise. As well as track friction noise and cabinet vibration noise are noise sources.

2. Shock Absorber

Installing a shock-absorbing table under the elevator mainframe can not only cut off the transmission structure of low-frequency noise, but also reduce the transmission rate of noise and the vibration of the elevator mainframe and the noise of the brake, thereby solving the problem of low-frequency noise caused by elevator vibration.

3. Elastic bracket

Use elastic brackets to change solid connections, reducing noise and noise transmission due to track friction.

4. Inorganic fiber spraying

The use of inorganic fiber spraying in the hoistway can not only improve the sound insulation effect of the hoistway, but also reduce the noise generated by the elevator hoistway as a whole.

III. Elevator sound insulation treatment effect

After the elevator sound insulation treatment plan, the indoor noise of the residents was detected at 26 decibels. Comply with the relevant regulations such as the "Noise Emission Standard for Social Living Environment".

The elevator sound insulation treatment plan is mainly based on vibration reduction, and the noise reduction methods are different according to the actual environment of the site. The most common elevator noise is vibration reduction treatment through equipment, which can effectively solve the elevator noise problem.
