盲听试验可信吗? 到底各种牌号、档次的放大器之间有没有人耳可闻的音质差异,若有的话差异究竟有多大?这个问题众说纷纭。有很多并不发烧的普通爱乐者一口咬定,除了少数低档的器材外,所有优质放大器的声音其实都是一样的,发烧友说得天花乱坠的各种所谓“音质差异”不过是发烧胡话或商业宣传罢了。看来,这个问题倒是能一针见血地把发烧友和非发烧友区别开来:凡是认为不同放大器之间存在客观音质差异的,就是发烧友,反之就不是发烧友。 既然发烧友和非发烧友之间的意见如此针锋相对,那么如何搞清事实真相呢?发烧友们津津乐道的各种放大器之间的“巨大差别”到底是玄虚还是事实呢?许多人认为,唯一客观、科学的方法是盲听试验,即将音响器材遮盖起来,不让参加试验者看到。这样,去除了各种会引起心理暗示的因素(如价格、外型)后,参加聆听者就能客观公正地对各种放大器的音质做出评判。
Blind listening test credible? In the end all kinds of brands, grades of amplifiers are there any audible differences in sound quality, if any, what is the difference? This issue varies. There are a lot of ordinary musicians who do not have a fever, and all the high quality amplifiers are actually the same except for a few low-end equipment. The various so-called “sound quality differences” described by enthusiasts are nothing but anecdotal or commercial propaganda Nothing more It seems that this problem is actually able to distinguish between enthusiasts and non-enthusiasts: Any difference between the objective that there is an objective difference between different amplifiers, is the enthusiast, and vice versa is not enthusiastic. Since the opinions between enthusiasts and non-enthusiasts are so tit-for-tat, how do you find out the truth? What is the “huge difference” between the various amplifiers that reverberates talk about? Is it the mystery or the fact? Many believe that the only objective, The scientific method is to blindly listen to the test, that is, audio equipment to cover up, to prevent the participants to see. In this way, after removing various factors (such as price and appearance) that can cause psychological suggestion, the participants can objectively and justly judge the sound quality of various amplifiers.
