Unverified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79% similarUnverified厚度并非越厚越好：橡胶垫超过15mm后隔振边际提升有限却明显影响稳定性，重设备放过厚软垫反而会晃动倾斜，重物减振应选高密度薄垫而非厚软垫79% similarUnverified隔绝楼下脚步声、拖椅子等结构传声（撞击声）需选高密度橡胶垫，密度≥1000kg/m³ + 厚度≥5mm，仅靠EVA发泡垫对低频撞击声几乎无效78% similarUnverified橡胶密度越高（≥1.1g/cm³）减震越稳、越耐用，但重量大、成本高且橡胶味更明显；健身房级密度地垫单块可达数公斤，家用需权衡搬动难度77% similarUnverified外底橡胶覆盖率≥80%（EVA裸露区域少）耐磨性显著提升，覆盖率<50%的全EVA大底虽轻但3-4个月即磨损露白77% similar
