如何欣赏到更美妙的声音（WhatHiFiSound+Vision）
参加日本音响展览会对于我么那里说就如同回到家里一般亲切。在那里我们看到当地的群众在听时是那么的认真:当demo的头几个音符响起时我们就发现他们已经闭上了眼睛、挺直了脖子开始集中注意力了。
我们不是说非要强调保持那种恍若着迷的状态，但是如果您要试着做对比的话您会发现那些丢失的细节足以使您感到惊讶。周围的噪音会遮盖住唱片的细节部分。如果说您的cd播放机具有90分贝的动态范围那就很好了，但是屋外的交通、家里的洗衣机或者是一般的家庭噪音这些背景噪音加起来等级就会有60分贝甚至更高了。如此，我们听到的声音质量就会折损。
因此我们就可以明白系统在夜深人静时发出的声音会比白天车水马龙时好得多。事实上还有许多因素也会使夜晚的音效听起来好得多，比如：稳定的电压和隔壁邻居家电视的干扰程度降低。音效变化的原因到目前为止最具说服力的解释就是背景噪音的影响。
使您的墙隔音，或者是精心设计一个能够专著欣赏音乐的视听房（虽然大多数家庭不具备这样的条件），也许下面的方法是您可以采用的。
紧闭门窗可以隔除大部分的噪音，选用材质较厚的窗帘也会有所帮助。关闭和器材同一环路上的主要家电，比如洗衣机或者洗碗机以减少有关电器的噪音，这么做也会使您的设备听上去更好。
您不必非地向发烧友们建议的那样去做：在听音室中不要有器材以外的任何电器设备，电视机、电话甚至是手表都被看作是禁止入内的犯人。
关闭潜在的无限电发射源，比如电子计算机、调光器会很有帮助。保证您的系统处于开机状态：大约一个小时的预热对绝大多数高保真音响系统都有好处。如果你是一直保持的是开机状态那么则可以马上享受音乐了！要是设备不象前面所说的那样进行预热，您虽然可以马上听到音乐但不是这个系统最好状态时的声音。
以上说的只是您应了解的有关听音的一个大致的框架，我们也不会使得这样的事情变得繁复到好像是教您去练习怎样呼吸那样，如果您能好好的接收声音的话那么得到的音乐效果会是最好的，当您一边读着书、看着杂志一边听着音乐，那只能说是倾听而不是全身心的投入的去欣赏（您的注意力是不是被扰乱和听到音乐的质量有关）。
另外，当您在关闭灯后再聆听音乐发现声音会更好一些，如果您没尝试过那请您不妨试试看。或许正如开头提到的那些日本发烧友那样是正确的，他们为了获得更好的感受从而闭上眼睛正是为了减少视觉上的干扰以免分心，
好了，各位倒上一杯您最喜欢的无论是15年的威士忌陈酿还是甜美的葡萄酒还是矿泉水，美国的一家杂志甚至推荐再叼上一根雪茄，让我们沉醉在美妙的音乐中吧。
我总结如下：
一、 保证听音环境不受到外界噪音干扰（有条件的话可以考虑听音室）
二、 降低其他家电（电脑、洗衣机、洗碗机、冰箱、收音机等）对设备的影响
三、 对设备进行预热（1个小时左右）
四、 专心的聆听（置身于音乐之中）
五、 倒上一杯美酒，叼上一根雪茄（警告:饮酒，吸烟可能影响您的健康）
How to listen
It really came home to us at the Japan Audio Fair once, where we saw the local crowd taking their listening seriously: no sooner were the first notes played in a demo than eyes closed, necks craned, and you could feel the concentration.
Now we wouldn't go as far as trying to enforce that trance-like state, but you'd be amazed how much more you'll get out of your system if you give it a chance. Ambient noise, for example, can mask much of the detail on a recording. It's all very well having a dynamic range of 90dB or so on your CD player, but if traffic, the washing machine or just general household noise creates a background level of 60dB or so, much of the quality will be lost.
That's one of the reasons why systems tend to sound better late at night. In fact, for all the other theories of late night improvements - cleaner mains, better voltage and even lower levels of interference from neighbours' TVs - by far the most persuasive argument is that of lower background noise.
Soundproofing your room - or having a dedicated listening room in a normal family home - is usually impractical, but there are some steps you can take.
Closing doors and windows will exclude much of the noise, while using thick curtains at the window will help, too. And not having major appliances like washing machines or dishwashers running will reduce the electrical noise on your ring-main, which may well make the system sound better.
You don't have to go as far as hi-fi fanatics once suggested: not so long ago it was considered heresy to have anything electrical in the listening room, with TV sets, telephones and even digital watches being seen as culprits. We remember once being thrown out of a demonstration just for carrying a camera with a flashgun!
But switching off potential sources of radio-frequency radiation, such as computers and dimmer switches, can help no end. So can keeping your system switched on: almost all hi-fi we know benefits from about an hour of warm-up. Eliminate this by keeping it powered up - you'll be able to enjoy the music immediately. That gets you off to the right start and you'll concentrate on the music immediately, not the system.
It's all part of being in the right frame of mind for listening. We're not about to get all mystical and suggest you try breathing exercises, but the fact remains that music sounds best when you're receptive to it. Read a book or magazine while the music's on and you're hearing, not listening: it's a matter of your attention being distracted.
If you've ever listened to your system with the lights out, you'll probably have discovered it sounds better; if you haven't, try it. Maybe those Japanese hi-fi fans had it right - reduce the visual distractions, and the sound gets better.
Oh, and a glass of your favourite whatever, be it a 15-year-old whisky, a nice glass of wine or even a mineral water, works wonders: one American magazine even suggests cigars and fine wines to suit the systems it reviews! Your system's probably better than you think it is - just give it an even chance.
