What's the noise like in Yantai Zhonghai International Job Building?

Some residents complained that basketball was played continuously from 7 am to 90 pm, and the noise exceeded 50 decibels during the day and night, which was noise pollution. In addition, the basketball stand is placed in the only way for the surrounding residents, occupying public resources, and the elderly and children are often smashed. I have failed to negotiate with the property for many times.

The standard usage of noise is noise. From the physiological point of view, any sound that interferes with people's rest, study and work and the sound that people want to hear, that is, unnecessary sound, are collectively called noise.
