其实想起来从大学开始就有这个征兆了。大学军训的时候，射击完之后，耳朵里面的嗡嗡声响了一整天。过后慢慢就没了。而同学都是可能半个小时就好了。
Actually i had some “sign” on it at the beginning of my university life. i remembered when we take a shot which make a really loud noise during military training, i was suffered by this buzzing sound for all day long. Of course, it disappeared after that. But my classmates typically got fine after half a hour.
不记得从某一天开始，隐隐约约的耳朵里面有高频的声音，我甚至还测试了下，感觉应该是5-10KHz的声音(点进去可以改变参数听不同频率声音http://onlinetonegenerator.com/)。就这样似有似无的，在夜深人静的时候要睡觉的时候感觉明显，戴上入耳式耳机更明显。
I did’t remember, since one day, i could hear some high frequency noise. it was only hit one ear in the early days, but it became worse – both ears. i’ve searched for some tests, the frequency i think, like, 5 to 10 KHz (click here to hear different sound in any frequency http://onlinetonegenerator.com/). this sound come and go, it became noticeable when i laid down, especially when i wear a in-ear earbud.
反正不管怎么样，查了下中文的好像除了祖国医学的解释其它的不多。就查了下英文的。感觉比较有价值，遂记录翻译如下，
Anyway, i want to know what happened, i’ve searched Chinese website, but there is no more than Chinese medicine which almost all disease can caused by same condition. Then i found some English website which is more clearer to explain this issue. So i make some translation into Chinese (my notes usually at the end of a sentence or paragraph, within the parentheses”(blah blah)”). Thanks to the original author.
