请教jeffery兄:
声阻抗是什么意思?怎么测?
听耳机造成的听力衰减有可能恢复么?
声阻抗仪是用来检测人的中耳功能仪器,声阻抗测试是客观听力测试方法的一种,所谓客观测试即在整个听力测试过程中无需受试者配合即可完成的测试。在许多医院的耳鼻喉科都有声阻抗仪,如果你在南京,我也可以帮你测试。
听力衰减或叫听力损失不管你是因为听什么造成的而只关心听力损失的类型,如果是传导性听力损失,那么通过药物或手术约70%~80%的人可以治愈,如果是神经性听力损失,那么目前医学上尚无很好的办法。 最初由 shzdq 发表

哈哈哈~~~~~~~~~~支持!:D ER-4MicroPro Earphones are in-the-ear,high fidelity transducers developed specifically to combine flat frequency response with isolation from external noise.These earphones provide 20-25dB of external noise exclusion,allowing the listener to hear the full dynamic range of recordings at lower reproduction levels.
ER4B:Lightweight and portable,High accuracy,Noise isolation,Flat diffuse-field-eaualized response,For specialized binaural recordings.
ER4S:Lightweight and portable,High accuracy,Noise isolation,Highest fidelity on standard commercial reordings.
ER4P:Lightweight and portable,High accuracy,Noise isolation,Higher sensitivity,Enhanced bass response. 4S,4P,4B的用途是不一样的,我想楼主所说的ER4指的应该是4B吧。
