In this study and analysis, it is found that the acoustic activities on the day of the project have a significant and comprehensive decline, and rise after the project. It is known that the acoustic activities of beluga whales in the communication category have a high correlation with environmental factors. Therefore, it is preliminarily believed that the reduction of acoustic activities of beluga whales is due to the urgency of noise to beluga whales.In this study, the analysis found that there was a significant and comprehensive decline in acoustic activity on the day of the project, and rebounded after the project, and it was learned that the acoustic activity of the white whale of communication and environmental factors were highly correlated, so it was initially believed that the decrease in the acoustic activity of the beluga whale was due to the urgency caused by noise on the beluga whaleIn this study, analysis, engineering acoustics day of the event prominently and comprehensive declined, and after the project picked up, that white whale acoustic communication category of activity and there is a high correlation with environmental factors, and preliminary view, white whale acoustic activity the decrease is due to the noise caused by pressing the white whale.
