What should I do if the residential property broadcast disturbs people?

Violation of the Law on the Prevention and Control of Environmental Noise Pollution. You can report to the local environmental protection bureau. In addition, such behavior also violates the property law and infringes on the rights of neighboring owners, which is an infringement. If the circumstances are serious, they can sue and demand the other party to bear civil liability for compensation: stop the infringement, eliminate the influence, apologize, compensate for the losses, etc.
