你对你的电脑满意吗,CPUPentium4,够快;显示卡,支持DirectX 9,够爽;512MB内存加上120G8硬盘,够大……很满意,对吗?不过,有一个问题你想过吗?同样是家用的电器,电视、影碟机为什么在播放时没有那种烦人的呜呜声,而电脑就有?电脑要发出嗓音似乎成为了很正常的事情,但它就是合理的?今天我们就要向噪音宣战,即使无法让噪音彻底消失,也要让噪音不再如此影响我们的电脑生活。 我国居民区域噪音现定的标准是:白天在50dB以下,夜间40dB以下。而一般家庭平时所用的各种家用电器的音量分别是电冰箱、电风扇、洗衣机为40～70dB,缝纫机、电视机、收录机、空调机等为50～80dB。而噪音的数值计算规律是噪音强度每增加一
Are you satisfied with your computer, CPUPentium4, fast enough; graphics card, support DirectX 9, cool enough; 512MB memory with 120G8 hard drive, big enough ... very satisfied, right? However, one question you think about it? The same is the home appliances, television, DVD players why playing is not annoying whining, and the computer there?

The average family usually used by the volume of various appliances are refrigerators, electric fans, washing machines for 40 ~ 70dB, sewing machines, TV sets, tape recorders, air conditioners, etc. for 50 ~ 80dB. The law of numerical calculation of noise is one for each increase in noise intensity
