“The brain processes these electrical impulses into sounds, then into words, and then into meaningful sentences and ideas,” neurologist Martin Kutscher, MD, told Additude. “Most of us do it effortlessly. Some adults have problems in converting these electrical neuronal impulses into meaning. We call these problems central auditory processing disorders.” Claire Benton, vice president of the British Academy of Audiology, told the BBC that adults’ brains may “forget” how to process ambient noises because of widespread headphone use. “You have almost created this false environment by wearing those headphones of only listening to what you want to listen to. You are not having to work at it,” she said. All that noise-canceling can cause your brain to overcompensate, according to David McAlpine, the academic director of Macquarie University Hearing, which can lead to increased sensitivity and what he calls “listening loss.” “If you have a listening loss, it’s like changing your brain’s encryption,” he told Quartz. “Even if you can change what you’re hearing, you may not get back to the brain state that you had before. It’s not reversible.” “I do think that we’ve let the big tech companies co-opt our listening habits, monetize it, and sell it back to us,” said McAlpine. “Their solution to the hearing problem is probably creating a listening problem.”
有人觉得飞机的飞行噪音很催眠吗？ 当然孩子哭那种不行。
所有主动降噪的估计都达不到降30db，入耳的都是硬的，不可能根据每个人耳朵调整，不舒服。套在耳朵外的，时间长压着不舒服。唯有工业用的那种最舒服，完全按照每个人耳朵调整。
不过如果想最大降噪，可以在foam plug加外戴主动降噪耳机

有用， 我买的入耳的就是因为觉得 外挂的太沉， 但是入耳的呆一段时间 耳朵会发炎。仅供参考
你还需要买静脉曲张袜子
耳塞我也用过，效果也很好，就是要取出来的时候不方便。
Bose QC可以无线也可以有线，在没有蓝牙联接的飞机上看电影的时候，有线联接方式很有用。
+1， 去年圣诞礼物之一就是给家人每人买了2双。
有链接吗？
应该买头戴式的，入耳的伤听力，去噪效果也不如头戴的。
我用过多款Bose和Sony的挂头式，其实还有微软，森海塞尔，和B&W的。不是最新的款，Bose QC 35，35ii，Bose 700和Sony XM2，XM3，XM4, 效果都非常好。非常推荐。
我试过苹果和Bose/Sony入耳式降噪耳机，效果都没有头挂式的好。当然两种耳机的便利性是有差异的。
飞机上其实噪音非常大，对我来说，降噪效果的优劣要比便利性重要。所以我坐飞机选挂头式的。
啥也不听也可以的，就是把噪音，尤其是飞机发动机的噪音给过滤掉。
飞机上发动机的噪音是非常大的。
飞机起飞时的噪音可以到105db，巡航时也有80-85db，都是非常高的了
我跟你差不多。飞机噪音不影响我睡觉。以前买过一个Bose入耳式的降噪耳机，用过几次后来就不用了。也因为我不太在飞机上看电影。
有意思，的确也很多关于经常使用耳机对听力的影响。并且建议减少耳机的使用时间。
当然长时间在高强度的音域下也会对听力造成影响。
bose costco 买的.
看过一个油管的分析的视频，好像说头戴式的比入耳的更多一层隔离，所以效果是最佳的
火车助眠，飞机完全不行，孩子哭闹更是大杀器，倒霉悲催的我每次飞长途前后三排内必有哭闹的娃。。。。
我也觉得bose夹头，只能戴sony的
