助眠场景主要需要遮盖低频环境噪音（伴侣鼾声、空调、车流），主动降噪(ANC)对稳态低频有效但对突发人声无效；追求安静睡眠更应看重被动物理隔音(NRR值)而非ANC参数

Unverified追求极限静音而选主动降噪(ANC)睡眠耳塞的用户需注意：ANC对低频稳态噪音（空调、风扇）效果好，但对突发性高频鼾声几乎无效，鼾声隔离仍需依赖物理封堵91% similarUnverified助眠场景优先选被动隔音（贴合耳道的记忆棉/硅胶）而非主动降噪（ANC）——ANC会产生底噪电流声，安静环境下反而干扰入睡，且耗电缩短续航90% similarUnverified助眠耳机应优先选择被动隔音的睡眠专用款而非主动降噪款，ANC降噪的底噪电流声和风噪算法在安静卧室反而更明显，会干扰入睡90% similarUnverified对声音敏感的浅睡者应优先选择物理被动降噪（贴合耳道的硅胶塞）而非主动降噪ANC，因为ANC电路的底噪电流声和风噪补偿在极安静卧室反而更明显88% similarUnverified睡眠场景下降噪能力比日常通勤更依赖被动隔音（物理密封）而非ANC主动降噪，因为ANC对打鼾、说话等中高频人声降噪效果有限，选购应优先看耳塞硅胶套/记忆棉的密封性与SNR隔音值≥26dB87% similar
