Unverified复合隔振垫（橡胶+软木/金属嵌片）宽频减振性能优于单一橡胶，软木橡胶垫（Cork-Rubber）尤其适合10-50Hz中低频且抗油性好，常用于精密仪器和发电机组基座86% similarUnverified音响/黑胶设备隔振应选软木或专用避震脚钉而非橡胶垫，橡胶会引入自身谐振染色，软木内阻尼线性更适合音频高频82% similarUnverified橡胶垫隔音效果好但重（5mm约7-9kg/㎡）、有橡胶味需通风、裁切困难；EVA垫轻便易裁切拼接但耐压性和隔声性差；发泡棉吸音好但不耐踩踏易塌陷，三者需按场景取舍82% similarUnverified软木橡胶复合材料兼顾了软木的高阻尼与橡胶的弹性恢复，但整体压缩变形量有限，对极低频大振幅振动的衰减不如弹簧隔振器82% similarUnverified橡胶软木复合垫（Sorbothane/软木-橡胶层压）对20-200Hz中低频振动衰减优于纯硅胶，适合洗衣机、空压机等有明显低频震动的设备81% similar
