据来自于美国和奥地利的研究人员报道,即使儿童每天接触的是不足以损害儿童听力的低度噪音,也有可能使儿童感到紧张。长期暴露于附近的声音(诸如公路和铁路的噪音)也可引起动机方面的问题。
Researchers from the United States and Austria report that children may feel nervous even if they are exposed daily to a low level of noise that is not sufficient to impair their child’s hearing. Long-term exposure to nearby sounds (such as road and railroad noise) can also cause motivation problems.
