为什么打鼾的人吵不醒自己？

你有没有被呼噜声吵醒的经历？打呼噜的人虽然“呼噜大作”，却完全吵不醒自己，让人好气又好笑，这是为何？一般来说，打呼噜多发生在深睡眠时期，这时打鼾者很难听到自己的呼噜声。此外，大脑熟悉自身节律，长期打呼噜的人对鼾声的敏感度降低，屏蔽掉了这一噪音。也有人称听到过自己的呼噜声，或被自己的呼噜声惊醒，这可能是由于呼吸道不畅引起的异常声音，听者把它和呼噜声混淆了。

Have you ever been woken up by snoring? Although snorers "snore loudly", they can't wake themselves up completely, which makes people angry and funny. Why? Generally speaking, snoring often occurs during deep sleep, when it is difficult for snorers to hear their snoring. In addition, the brain is familiar with its own rhythm, and people who snore for a long time are less sensitive to snoring, thus shielding this noise. Some people say that they have heard their own snoring, or were awakened by their own snoring, which may be due to abnormal sound caused by poor respiratory tract, and the listener confused it with snoring.
