HiFi beats headphones on sale sound quality analysis: finally seeing theism, metaphysics

From the moment when the HiFi industry was born, "Metaphysics" will follow suit. How to evaluate the quality of a product? There is a lot of different opinions and people often just come up with plausible fuzzy standards such as Treible Sweet, Medium Quotation, and Bass Strength.

Not only that, the HiFi player's use of means to improve the sound quality looked rather ridiculous, so that it was finally ridiculed, "The warm tone of the thermal power, cold water and electricity, beats earbuds nuclear power has electronic taste".

These phenomena are much less common in other consumer electronics products. For example, to evaluate the picture quality of certain displays and TV sets, although there are also subjective opinions, the composition of metaphysics can be far from the sound quality.

Why does content often become "mysterious" when it comes to sound quality? Let's talk about the reasons together today.

Sound quality is difficult to quantify: test software nobody knows

What kind of sound quality is better? Measuring sound quality is not without specific parameters, but it is less well-known than the objective parameters of sound quality, such as measuring CPU performance, measuring GPU performance, and measuring screen display quality.

Even enthusiasts, few people can know the parameters such as total harmonic distortion, intermodulation distortion, resolution, and frequency response curve of a certain type of equipment.

On the other hand, even if these objective parameters for measuring sound quality are set, most people do not know what they really mean or how to judge the sound quality from these objective parameters. For example, the total harmonic distortion, from the perspective of fidelity, of course, the lower the better, but the same distortion value, due to the different frequency bands of distortion, can be different to a sense of hearing difference; and for example, the frequency response curve, flat is very natural It is important, but according to the characteristics of the sounding unit, it is necessary to adjust the curve to create a more natural sound field. Compared with the visual sense, the auditory senses are more ambiguous and easier to change over time. To compare the different colors of the screen, the eyes can easily be separated. However, this does not mean that people's senses are precisely accurate. I believe many people have played psychological games based on visual illusions, such as distinguishing between the same gray in the black and white background which is brighter and darker. Vision is still easily affected by the environment, let alone hearing? Under the influence of some psychological hints, such as audio files of the same specifications, there is a golden label on top of a certain one, and your evaluation of sound quality may be very different. On the one hand, we must understand some basic electro-acoustic knowledge. On the other hand, we must practice more. If there is no condition, then simply do not play, you need to know that the actual cost of many equipment is terribly low, although some things are valuable, but there are also shoddy goods. Finally, it is hoped that the consumer circles related beats by dre to sound quality can come The more rational, the more healthy it is.
