Can noise-cancelling headphones cause hearing problems?
降噪耳機會導致聽力問題嗎？
文字稿
Do you own a pair of noise-cancelling headphones?
你是否擁有一副降噪耳機？
Well, for some that do, they’re wearing them for hours on end, and some audiologists are concerned this might have an impact on their sound-processing skills.
一些有降噪耳機的人會連續幾個小時戴著它們，而部分聽力學傢擔心這會影響他們處理聲音的能力。
The theory goes that by blocking out everyday noises like car engines, the brain might struggle to then filter out what is just noise, and what is an important sound signal, making it harder to pick out those alerts or someone speaking directly to you.
有理論認為，在屏蔽諸如汽車引擎等日常噪音之後，大腦可能難以分辨哪些是噪音、哪些是重要的聲音信號，使得人更難識別警報聲或他人直接對自己說話的聲音。
When someone has trouble identifying speech or understanding sounds, but their hearing level is normal, it could be what’s known as an auditory processing disorder.
如果某人識別言語信息或理解聲音有困難，但又具有正常的聽力水平，那麼這個人可能患有聽覺處理障礙。
APD can be complex to diagnose.
APD（聽覺處理障礙）的診斷十分復雜。
But treatments can help. For example, with apps that train you to pull out speech from background noise.
但有些治療方法能幫助緩解這一癥狀。比如，有些應用程序能夠訓練你從背景噪音中提取言語信息。
Some audiologists say they’re now seeing more referrals for people with difficulties processing sounds.
一些聽力學傢表示，他們現在會看更多因為處理聲音有困難而轉診的病人。
And they’re calling for more research looking into a possible link between APD and overuse of noise-cancelling headphones.
並且他們呼籲更多研究能夠詳細調查聽覺處理障礙和過度使用降噪耳機之間的潛在聯系。
Although these headphones have their benefits – helping to prevent high frequencies and loud noises from damaging your ears – could they have some unintended consequences too?
雖然降噪耳機有其好處，比如它能幫助你防止高頻噪聲或者大音量的噪音對你的耳朵造成傷害，但這類耳機是否也可能導致意外的後果呢？
