在我们所日常生活当中，白天我们的周围居民区声音一般是不会超过50分贝的，当出现在夜间的时候普遍降低到45分贝左右，人们是适宜的工作环境当中65分贝左右，还是能够维持正常的反应以及注意力。一旦超过这个数值，人们在高分贝环境当中长时间的工作就会导致，听力下降，情绪烦躁，严重会出现神经衰弱等现象；

　　工业尾气发电机组在正常工作的时候会出现噪音扰民的现象，工业尾气发电机组的噪声一般处在距离机组1米处噪声，以250kw发电机组为例，一般会在105分贝左右，因此再出现噪音要求比较高的地方一般会做静音处理；

　　听音乐 80db，儿童80分贝以上噪音环境中生活，造成聋哑者可达50%，噪声级只有在80分贝以下时，才能保持40年长期工作不致耳聋；在100分贝时，只有60％的人不会耳聋。如果人长期生活在80分贝以上的环境里，会引起情绪烦躁、听力下降。

　　In our daily lives, the noise level in residential areas during the day usually does not exceed 50 decibels, and generally drops to around 45 decibels at night. In a suitable working environment, the noise level is around 65 decibels, which can still maintain normal reaction and attention. Once this value is exceeded, prolonged work in a high-decibel environment can lead to hearing loss, irritability, and even severe symptoms such as neurasthenia. Industrial exhaust gas generator sets can cause noise disturbances during normal operation. The noise from industrial exhaust gas generator sets is generally measured at a distance of 1 meter from the unit. Taking a 250kw generator set as an example, the noise level is usually around 105 decibels. Therefore, in places where high noise levels are required, noise reduction measures are usually taken. Listening to music at 80db can cause deafness in up to 50% of children living in noise environments above 80db. Only when the noise level is below 80db can prolonged work for 40 years without causing deafness be maintained. At 100db, only 60% of people will not become deaf. If people live in an environment with noise levels above 80db for a long time, it can cause irritability and hearing loss.

　　85分贝以下可造成轻微听力损伤；85分贝－90分贝可造成少数人噪声性耳聋；90——100分贝可造成一定数量的噪声性耳聋；100分贝以上，就会造成相当数量的噪声性耳聋，以上这些属于慢性噪声性耳聋；105分贝以上—— 5分钟 精神分裂。

　　Below 85 decibels, it can cause mild hearing loss; between 85 and 90 decibels, it can cause noise-induced deafness in a small number of people; between 90 and 100 decibels, it can cause a certain number of noise-induced deafness; above 100 decibels, it can cause a considerable number of noise-induced deafness, which are all classified as chronic noise-induced deafness; above 105 decibels for 5 minutes - schizophrenia.

　　噪音对人的中枢神经有损害作用，并且能诱发心血管系统疾病，在　强烈的噪音环境中进食，胃肠的毛细血管会发生收缩，消化液的分泌和胃肠的蠕动会减弱，使正常的血　供受到破坏。强烈的噪音还会造成妊娠异常、儿童智力发育障碍。所以，日常生活中要尽量减少噪音的来源和传播。

　　Noise has a damaging effect on the human central nervous system and can induce cardiovascular diseases. Eating in a strong noise environment can cause the capillaries in the gastrointestinal tract to contract, weaken the secretion of digestive juices and the peristalsis of the gastrointestinal tract, and disrupt normal blood supply. Strong noise can also cause abnormal pregnancy and impair children's intellectual development. Therefore, we should try to reduce the sources and dissemination of noise in daily life.
