  他们所提出的降噪措施如下:紧固振动筛上的所有部件,特别是需要经常更换的筛板,避免由于个别部件的松动而产生的额外振动;将冲孔钢筛板更换为弹性模量小、冲击噪声低的聚氨酯筛板或者橡胶筛板;在筛箱的侧板、入料给料口、排料口和接料底盘内加贴橡胶板,这样可以有效地抑制侧板的高频振动,减少辐射噪声;采用柔性辐板齿轮来代替钢齿轮,即在齿轮的辐板上利用橡胶弹性体传递扭矩,吸收齿轮啮入、啮出所造成的振动;用橡胶弹簧替代钢制弹簧,以减少冲击;在激振器的体外加装软式隔声罩;对轴承的内外套之间加以阻尼处理,轴承的滚动体可以制作成空心滚动体或者在空心滚动体的内部加入阻尼材料,这样能够减小轴承的振动和降低轴承的噪声。(振动筛的种类很多如电磁振动筛,直线振动筛等) 。
