我所有ZS-300D振动台、冲击试验台和机械振动各二台。由于工作需要,经常两三台设备同时在一间40米2的室内进行试验,噪声震耳欲聋,其值在110～120分贝(A)。为此,我们采取隔声、吸声及减振措施,进行了初步治理,取得了良好的效果。 隔声措施 隔声措施是将噪声源屏蔽起来,通过装在 I have all ZS-300D shaker, impact test stand and mechanical vibration of the two. Due to work needs, often two or three devices at the same time in a 40 m 2 indoor test, the noise deafening, its value at 110 to 120 decibels (A). To this end, we have taken sound insulation, sound absorption and vibration reduction measures, conducted a preliminary governance, and achieved good results. Sound insulation measures Sound insulation measures are shielding the noise source, installed by
