Why do my ears ring after a loud concert?为什么在大声音乐会后我的耳朵会嗡嗡作响？
No discussion of loud sounds is complete without someone asking this question. It is a widespread experience, but the answer to the question "Why?" is not clear, at least to me. In general terms it would seem likely that it results from some level of trauma to the inner ear, where the hair cells respond to sound by producing nerve signals which travel to auditory area of the brain. 如果没有有人问这个问题，关于大声响的讨论就不算完整。这是一种普遍的经历，但这个问题‘为什么’的答案并不明确，至少对我来说是这样。总体而言，似乎可以认为这是由于内耳某一层的创伤引起的，内耳中的毛细胞通过产生神经信号来响应声音，这些信号传递到大脑的听觉区。
Those nerve cells of the inner ear normally fire only upon stimulation by a sound signal, but it is a tempting speculation that with trauma, they may "self-fire". This then is one conjecture about the ringing in the ears, that the nerve cells become a "relaxation oscillator", firing and then firing again as soon as they are recharged. The ringing is usually perceived as a high pitched sound, and that might correspond to the frequencies of maximum sensitivity. If it is some kind of self-firing process, then self-firing at the maximum sensitivity frequencies seems plausible. 那些耳内神经元通常只有在受到声音信号刺激时才会放电，但有一种诱人的推测是，在创伤情况下，它们可能会‘自发放电’。这便是一种关于耳鸣的推测，即这些神经元可能成为‘弛豫振荡器’，在充电后立即再次放电。耳鸣通常被感知为一种高频声音，这可能对应于灵敏度最高的频率。如果这是一种自发放电过程，那么在最大灵敏度频率上自发放电似乎是有道理的。
The ringing could be considered to be a type of temporary tinnitis, and the relaxation oscillator mechanism could also be proposed for tinnitis as well. But there is a considerable body of information that suggests that the brain is involved in tinnitis, and that some of it occurs in the brain itself. 耳鸣可以被视为一种暂时性的耳鸣症，同时也可以提出放松振荡器机制来解释耳鸣。但有一大批信息表明，大脑在耳鸣中起作用，且其中一些现象发生在大脑本身。
Any insights on this intriguing phenomena would be appreciated. 任何关于这一引人入胜现象的见解都将不胜感激。
