聽覺受損無法復原 耳筒逾100分貝音量從事娛樂業四成人聽力受損
耳鼻喉科專科醫生黃漢威表示，耳鳴是聽力受損的先兆，過去有藝人、音樂家因耳鳴而做聽力測試，結果測出高頻退化，雖然暫不影響溝通，「但（對方）講嘢把聲尖就會聽得辛苦，同一嘈音環境持續10至15年就會越來越差」。而且聽力一旦受損，將不可復原。黃漢威指出，聽力退化在聆聽英語時較明顯，「因為英文S、T、D屬於高音，聽唔到之後就發現聽力有問題，所以外國人一般比港人早察覺」；而廣東話音節較平，即使有高頻退化也不易察覺。娛樂業人員雖不能像藍領般戴上耳塞，但可用「專業監聽耳機」保護聽力，由於耳機是倒模製造，能有效隔絕環境噪音。〔轉載〕

One observation of note:
Since the 80s with the invention of Walkman and now the iphones/ipads or i-whatever, youths and young adults spent more and more time wearing earplug types of headphones, from listening to webcast/podcast to music and even playing games and online chat (skype), etc. Most of them are unaware of how loud they have turned their earplugs volume up to until the damage is done.
combined with urban living's ambient noise (20+dB higher than suburbs/outskirts), these folks would typically crank up their volumes just to overcome (overwhelm) the background noise....
Over time, they will suffer from severe hearing loss....and they will have to speak/crank up the volume even louder than a generation or 2 ago.
Sad fact.
I don't listen to earplugs very often (maybe once every several months, mainly podcasts, for about 1hr or less per session), and I'm trying my best to preserve my hearing (still good up to 16kHz, given my age).
To all the LYKs out there: protect and preserve your hearing! stop listening to those apple ipods/iphones/itunes using earplugs!

@yuusaku,
It's never too late to start taking care of your hearing.
Start by not listening (or limit your listening) to iphone/ipod using earplugs.

Do you think using the noise cancellation headset would help? Or make it even worse?

@ fibbi,
I have owned 2 pairs of noise-cancelling headphone/earplugs so far, none of them worked to my satisfaction.
It's based on phase-cancelling methodology (using electronics), which only looks good on paper, but sounds weird in actual application.
I'd suggest to use ordinary earplugs/headphones by restrict the usage time and also lower the volume to just a slight notch higher than whispering (so long as speech is comprehensible then that's good enough).
Depending on how sensitive (or damaged) your hearing is now, this will help extend the service life of your hearing.
There's no way around this. Both cranking too loud (damage your hearing in the cochlea), combined with hearing fatigue due to extended listening period will lead to ringing and permanent damage...
