Unverified入耳式（硅胶耳塞）被动隔音+主动降噪叠加效果远优于半入耳式；追求降噪必选入耳式，半入耳（如AirPods标准版）几乎没有物理隔音86% similarUnverified入耳式（硅胶耳塞）降噪效果比半入耳式好10-15dB，追求降噪必选入耳式；半入耳式无法形成物理密封，主动降噪对中低频几乎无效84% similarUnverified音量越大传导越清晰但胎儿听力风险越高，安全做法是选择带硬件音量上限锁定的产品，而非依赖手动调节83% similarUnverified硅胶耳塞降噪能力有限，主要隔绝轻度环境噪音，无法有效阻隔打鼾、交通噪音等中高分贝声源，对强降噪有需求应选择专业泡棉耳塞或主动降噪耳塞83% similarUnverified低频噪音（马路车流、鼾声）比高频更难隔绝，慢回弹PU海绵耳塞对低频衰减优于硅胶，硅胶三节翼款对高频（说话声、键盘声）更有效83% similar
