随着音响设备越来越广泛地进入人们的生活中,对其质量问题也就提出了越来越高的要求。但对质量好坏的评价,本身就存在着主观评价和客观评价(即拟定出反应质量的一些参数,然后用实验手段进行检验)之间的不一致性。当然,人们总是力求这两种评价的一致,即要求人们拟定的参数最好能完全代表着设备的质量。然而,这个问题是声学中至今尚未解决的问题。但对音响设备来说,需要人们回答的一个更迫切,更重要的问題则是:人们为什么能从负载扬声器的发声中区分放大器的音响质量?当然,这是由于放大器所固有的非线性失真不同(在放大器的其它性能,如频响、功
With the sound equipment more and more into people’s lives, the quality of its problems also put forward higher and higher requirements. However, the assessment of the quality of the quality itself there is a subjective evaluation and objective evaluation (that is, to develop a number of parameters of the reaction quality, and then use experimental means to test the inconsistency). Of course, people always seek the agreement of the two kinds of evaluation, that is, the parameters that are required to be formulated by people are best to completely represent the quality of the equipment. However, this problem is so far unsolved in acoustics. But one of the more pressing and important questions people need to answer for audio equipment is why people can distinguish the sound quality of the amplifier from the sound of the load speaker. This, of course, is due to the inherent non-linear distortion of the amplifier (Other features in the amplifier, such as frequency response, power
