Unverified带陶瓷或多层复合均压膜的耳塞可将气压变化速率降低约50%-80%，比单纯泡沫耳塞更能缓解起降耳痛；泡沫耳塞几乎无调压作用，只能隔音81% similarUnverified泡棉耳塞的实际降噪效果高度依赖正确佩戴手法：需将耳塞充分搓细后，拉直耳道插入并按压保持约30秒待其膨胀——操作不到位将导致实际降噪量远低于标称NRR值81% similarUnverified被动耳塞的降噪值高度依赖佩戴深度：泡棉需搓细后塞入并等待膨胀密封，若只塞在耳道口，实际隔音可能损失10dB以上，达不到标称NRR81% similarUnverified调压滤芯在缓解耳压方面有口碑支撑，但代价是隔音量显著低于同价位普通硅胶/海绵耳塞；两种需求难以兼得。79% similarUnverified均压滤芯通过缓慢平衡机舱气压变化来减轻耳鸣与耳痛，对飞行中耳气压伤敏感者有实质帮助，但不能替代医疗处置。78% similar
