Why is the plane noise so loud over Taiyuan?

The reasons for the high noise over Taiyuan are as follows:

1. Airplane route: Taiyuan is located in Jinnan area, and there are several airports around it, including Taiyuan Wusu International Airport, Changzhi Wangcun Airport and Yuncheng Guangong Airport. If the plane takes off, lands or passes through these airports, it will produce noise. In addition, if the flight route just passes through Taiyuan city, it will also cause obvious aircraft noise.

2. Meteorological conditions: Some weather conditions, such as low pressure and heavy fog, will affect the speed and direction of sound propagation, making the sound of aircraft easier to be heard.

3. Flight altitude and type: Different types of aircraft will make different noises at different altitudes. For example, a jet airliner is usually noisier than a turbofan airliner. In addition, during the take-off and landing phase or during the climbing and descending process, the aircraft will also produce more noise. The above are some reasons that may lead to the noise of aircraft over Taiyuan, but the specific situation needs to be judged according to the actual situation at that time.
