Complaining about low-frequency noise makes it difficult to sleep.

Since the transformation and operation of Howard Johnson Leisure Center three years ago, the owners of Building 38 of Shanshuiyuan haven't had a good rest. "I really can't stand it, especially in the dead of night. The buzzing sound makes people unable to sleep at all, and the rest at night is not good, and the work during the day is also affected." Mr. Director of Housing Industry said, "We know that it is the low-frequency noise of the boiler outdoor unit in Haosheng Leisure Center."

To this end, Mr. Ren and others have repeatedly reported to the property department, but the problem has never been solved. On March 29th, the District Urban Management Law Enforcement Bureau received a letter of complaint signed by 15 people.

Solve the problem, find the crux of the problem, and restore the peace of residents.

After receiving the complaint, the District Urban Management Law Enforcement Bureau attached great importance to it and decided that the petition acceptance center of the bureau would take the lead and invite the staff of the environmental monitoring station of the District Environmental Protection Bureau to go to the scene to deal with it together with the squadron directly under it. During the inspection, it was found that Howard Johnson Leisure Center had a boiler, and the outdoor unit of the boiler was installed on the first floor external wall of Unit 38 on the west side of Shanshuiyuan. The noise and vibration waves generated by the operation of the equipment spread along the wall, which has a great impact on the lives of residents in this building. The staff of the environmental monitoring station in the factory detected the noise generated by the equipment during operation, but the noise generated by the equipment did not exceed the standard. The noise generated by this equipment is low-frequency noise, although it has an impact on the normal life of residents, but the noise value it produces often does not exceed the noise limit specified by the national environmental protection standards.

According to the site situation, in order to solve the practical problems, law enforcement officers thought of a way, that is, asking the leisure center to remove the outdoor boiler from the external wall of the building and put it on the ground, and suggesting to stop the boiler operation at 2 1:00 every night to reduce the impact of noise on residents.

Pay a return visit, enforce the law efficiently and win the satisfaction of the masses.

On April 1 1, the District Urban Management Law Enforcement Bureau telephoned the owner's representative and the industry committee of Building 38 in Shanshuiyuan to pay a return visit to the governance effect. Mr. Ren, the owner's representative, and Mr. Jin, the director of the industry committee, expressed great satisfaction. "The annoying buzz has disappeared, so I can have a good sleep at night. Thank you very much for your law enforcement bureau! "

Note: Low-frequency noise refers to sound with a frequency below 500 Hz. There are five main types of low-frequency noise sources in residential quarters: elevators, transformers, high-rise water pumps, central air conditioners (including cooling towers) and traffic noise. High-frequency noise attenuates quickly with distance or encountering obstacles, while low-frequency noise attenuates slowly and has long sound waves, so it can easily cross obstacles, rush a long distance, and go straight through walls to people's ears. Long-term interference by low-frequency noise is likely to cause neurosis such as neurasthenia, insomnia and headache.
