[影视媒体♡] 失真度听力分辨能力测试 and 高音范围测试

[复制链接]

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

  - 8kHz
  - 10kHz
  - 12kHz
  A 14.1kHz
  A# 14.9kHz
  B 15.8kHz
  C 16.7kHz
  C# 17.7kHz
  D 18.8kHz
  D# 19.9kHz
  E 21.1kHz
  F 22.4kHz

  8kHz:
  You're really getting on a bit
  You are either old or have really messed up your hearing by turning your amp up to 11 and listening to Spinal Tap. Or both.
  The highest pitched ultrasonic mosquito ringtone that I can hear is 8kHz
  
  10kHz:
  You can't remember my teens
  But you can just about hear some of these tones that those youngsters are on about so you're feeling moderately smug.
  The highest pitched ultrasonic mosquito ringtone that I can hear is 10kHz
  
  12kHz:
  You're in a mid life crisis
  Your ears aren't what they once were and you have resorted to doing online hearing tests.
  The highest pitched ultrasonic mosquito ringtone that I can hear is 12kHz
  
  14.1kHz:
  You're not a hoopy frood
  You thought you were really with it and in with your younger colleagues but they just laugh at you because you can't hear beyond this!
  The highest pitched ultrasonic mosquito ringtone that I can hear is 14.1kHz
  
  14.9kHz:
  You are a thirtysomething
  You're a little frustrated that you can't hear all the tones that the young 'uns can but will be more than happy if it means you don't have to listen to their damn ringtones on the bus anymore.
  The highest pitched ultrasonic mosquito ringtone that I can hear is
  
  15.8kHz:
  You are in your twenties
  You can still hear reasonably well and you can play this without my old fart colleagues hearing it which makes you feel kinda good.
  The highest pitched ultrasonic mosquito ringtone that I can hear is 15.8kHz
  
  16.7kHz:
  You are about 20 years old
  The teen repellent will no longer foil you, but you can still hear some pretty high tones.
  The highest pitched ultrasonic mosquito ringtone that I can hear is 16.7kHz
  
  17.7kHz:
  You are the typical teenager
  You can hear the frequency of the mosquito teen repellent - but probably not for much longer!
  The highest pitched ultrasonic mosquito ringtone that I can hear is 17.7kHz
  
  18.8kHz:
  You are an easily repelled teenager
  The mosquito device was made for the likes of you. You are probably begging to make the noise stop!
  The highest pitched ultrasonic mosquito ringtone that I can hear is 18.8kHz
  
  21.1kHz:
  You are a dog
  Or maybe you are a mosquito, you certainly can't be human.
  The highest pitched ultrasonic mosquito ringtone that I can hear is 21.1kHz
  
  22.4kHz:
  You are a liar
  You claimed to be able to hear a tone that contained absolutely no sound!
  The highest pitched ultrasonic mosquito ringtone that I can hear is 22.4kHz

You are a dog
Or maybe you are a mosquito, you certainly can't be human.

对这类测试我有两个疑惑

1.扬声器或者耳机最高可以发出多少频率的声音
2.声卡上是否有滤波将高于20K的滤掉

对于1,比如最街机的耳塞 森海塞尔MX400 http://www.360buy.com/product/138576.html
频响范围  18-20000Hz

音箱低价2.1的不用看,2.0的以漫步者 R1000TC http://www.itus.cn/hardware/sound-box/market/24227.shtml
的频率响应范围是20Hz-20kHz

低频段的已经肯定的知道这些参数是有水分的,50~60Hz的响应都很差,高频段的估计也好不到哪里去

那么,发声设备根本发不出的声音,怎么测试呢。。。。

增加了新方法,相当考验耳机哦。
我这个破耳机只能听到-12dB... ...
想要测听力,还要找个好耳机啊
