It was learned from the Propaganda Department of Xinxiang Municipal Committee that Xinxiang Municipal Government has organized public security, fire control, seismological bureau, safety supervision and other departments to actively investigate all the places where fires may occur around 1 on the afternoon of October 27th1,and no abnormalities were found. Xinxiang municipal government once again reminded the general public not to spread rumors.

As early as a few years ago, similar things happened in Jiangsu, Anshan, Chengdu and Liaoning. The public also heard two loud noises, and many people were awakened by the noise. At first, the citizens thought there was a violent accident or earthquake. However, after investigation by local government departments, there was no sign of severe fire in the incident area, nor was it caused by an earthquake, and the sound source was unknown. According to this analysis, some experts say that loud noise is related to sonic boom.

Some netizens analyzed that loud noise may also come from "sonic boom". It is understood that when the speed of an object is close to the speed of sound, it will produce strong resistance, which will cause the object to oscillate strongly and the speed will be attenuated. This phenomenon is often called sound barrier. When breaking through the sound barrier, because the compression of air by the object itself cannot spread quickly, it gradually accumulates on the windward side of the object, and finally forms a shock wave surface, on which the sound energy is highly concentrated. When these energies reach people's ears, people will feel a short and extremely strong explosion, which is called sonic boom.
