| 摘 要： | 针对笔记本电脑噪声源、噪声特性和影响噪声的主要因素进行了实验研究.结果表明:笔记本电脑机壳对噪声的屏蔽或吸收作用使噪声降低的趋势并没有出现,反而导致笔记本电脑正面操作人员所在位置的噪声增大;进气口的封闭也并不一定使该处的气动噪声值降低;噪声指向性研究发现,噪声值最高处并不在风扇出风口上方,而在出风口的对侧.

| Abstract: | As the fan causes aero-noise and affects the user's comfort,the acoustic characters of the module is attracting more and more concerns.Experiments were carried on to study the noise sources,the noise characters and the main factors influencing the noise level.The difference between the aeronoise of the thermal module and the whole computer system was compared,and then its transmitting characters were derived.The influence of the I/O port on the aero-noise was studied experimentally also. |
