在别处看到的，觉得好玩就转过来。
测试耳朵听力两项：失真度听力分辨能力测试和高音范围测试。
高音范围测试：
1. 听力分辨能力测试（失真度测试，木耳or金耳）：
http://www.klippel-listeningtest.de/lt/instructions.html
如果是在12db ~ -6db之间
那么你的耳朵听20元和200元的耳机是没区别的
点击上面的Sample A/Sample B试听
然后觉得那个Sample A是失真的音频
就点击A is Distorted
同样的，若觉得Sample B是失真的音频
就点击B is Distorted
注意的是：文件AB是不定出现的，没有固定规律，全靠耳朵哦。
补充：请尽情使用你最好最烧的设备（建议使用耳机）来进行该测试，看看自己能达到怎样的水平
如果是在12db ~ -9db之间的话，对于您的耳朵，2000元的家庭影院和20000元的家庭影院是没区别的，所以买一台DVD+电视机就可以了，声音请用电视的喇叭直接播放……
如果是在-12db ~ -24db之间的话，您的耳朵已经能够分辨出很多的声音细节了，您的家庭影院的预算应该控制在10000-40000左右，这样能保证您的耳朵不会被低劣的声音效果所折磨。
对应配置：OPPO 980 DVD（1700元）+天龙 3805 功放（4500元）+ BOSE AM10 5.1音响（7000元）= 13200元
如果是小于-27db 后，那么恭喜您！您的耳朵非常灵敏了！它配得起任何价位的家庭影院！
对应配置：pioneer BDP-95FD 蓝光DVD（13000元）+安桥 NR1000 功放（27000元）+宝华7系（80000元）= 120000元
