Installing a good car stereo for our car is a means, not an end. Our GOAL IS not to BUY a lot of car stereo equipment to decorate the car, but to get a better sound effect. The standard of good car audio equipment evaluation is whether it can be played back to restore the real live music effect. In evaluating the quality of music playback by audio equipment, there is generally a difference between objective test and subjective evaluation.

Car audio professionals often from the perspective of technology to evaluate the advantages and disadvantages of car audio equipment, such as the first to see the technical indicators of equipment, if the indicators achieve international standards so it is a set of good equipment. Again is the use of instruments to measure, for example, we often in the car audio competition to see the use of real-time analysis of the spectrum instrument, sound pressure meter and other instruments to measure. But most of the time, as the most important means of sound quality evaluation, of course, depends on our ears. This is because there are some things in beautiful music that cannot be expressed by technical indicators, such as timbre, quality, level, orientation, etc.


When watching multimedia cinema, commonly used sound movement sense to express the performance of the equipment on the sound and image movement is good or bad, but also can not be expressed by technical indicators. In the evaluation of the sound effect of equipment, generally choose more than two sets of equipment comparison, of course, before listening to understand the technical indicators, choose the indicators of good equipment comparison, can save time. During the evaluation, the subjective listening is the main method, and the objective instrument test is the auxiliary method.

在此,推荐用交响乐的重放来判别汽车音响器材的效果。交响乐的表演形式是动用了最多乐器的演奏,这样可以对重放声的分离度、平衡度、解析力等各方面进行评价。例如,在我们听的时候,会听到小提琴在乐队的左方,大提琴在乐队的右方,打击乐在乐队的后左方,如果音响器材能够在汽车里重放时基本能清晰的反映出整个乐队中各个乐器的所在位置,那么器材重放声的声场定位就非常好,如果器材对交响乐的重放声杂乱无章,整个乐队乐器的声音混在一起,则说明器材的重放质量较差。
