2020-09-03 From the aspect of environmental protection, all the sounds that affect people's normal study, work and rest, and the "unwanted sounds" of people on certain occasions, are collectively called noise. Such as the roar of machinery, the sound of various vehicles, the sound of horns, the noise of people and various sudden sounds, etc., are all called noise.

① 30~40dB is an ideal quiet environment.
② 70 decibels will affect the conversation.
③ Long-term living in an environment above 90 decibels will severely affect hearing and cause neurasthenia, headaches, high blood pressure and other diseases.
④ If you are suddenly exposed to a noise of up to 150 decibels, the slighter Tympanic membrane will ruptures and bleed, and the ears will completely lose hearing ability; the severer will cause heart resonance and cause death.


Denmark recently announced the results of a study showing that street noise may be one of the causes of high heart disease. It is recommended not to stay in the car for too long. These researchers included 57,053 healthy people aged 50 to 64 between 1993 and 1997, and conducted long-term monitoring and follow-up. The average follow-up time for these patients was 9.8 years. From 1988 to 2006, these people were exposed to street noise and different air pollution.
w cases of cardiovascular disease patients was first discovered. There is an obvious causal relationship between these noise exposures and cardiovascular diseases.
