How to judge the sound quality of the stage

1, the low frequency generated by the poor speaker can be deafening, but it is the kind of bloated thick, lack of sense of hierarchy and strong. The low frequency should be clean and crisp, clear, not muddy death dreams like, even though a variety of musical instruments such as the size of the low frequency bass guitar and Piano drums, bass, can easily distinguish, so don't be deceived by the feeling of low frequency, low frequency sound as clean after all inferior to natural. Bookshelf type AV horn two sound road some heavy weight advertised, many buyers will think it is very value, because we will first choose horn weight, whether horn more the value of this statement is actually not, according to the speaker the heavier, dense plate of a box body (MDF or HDF) is thick, thick wood is not easy to produce resonance; another speaker is heavier, bass single magnet is bigger, so the bass is deep. But the average estimate of the speaker shelf type 38 cm high, the general weight of six or seven kg in weight should be even, if more than the weight of many, even as high as three, forty kilograms of weight, it may be a gimmick, the overall quality is not much help.



2, if the
The voice is the most commonly heard voice, it is not difficult to detect the pros and cons, pay attention to whether there is an unusual voice of the human nose, or the feeling of being a mouth. Some speakers of the “ box sound ” the same will greatly interfere with the intermediate frequency, so that the frequency of the sound is blurred. If colourations compared to other frequency noise pollution is more serious, because the most audible sound frequency, or frequency of music are concentrated in the intermediate frequency range, which is almost all kinds of music, will become the obstacle to play.



3, the flexibility test of high frequency

The poor quality of the high frequency is a shrill, piercing, and, in extreme cases, the sound of a violin or soprano voice into a sharp brake noise. In the same way, the different instruments in the high frequency sound can produce different textures, and the high frequency sound can be distinguished. And then the advantages and disadvantages of a high frequency can even tell the difference between the two different years, different wood played by the different phonology. The key is easy to grasp the high frequency sound is not good people listen and intimidating, pores erect, would not be heard the more tired, and should be soft and tough and elastic, smooth and high level to the highest point can easily hear no sound (of course not to tune the singer's reference
)

Test of high volume and sound field like stable, some speakers volume, but the volume in advance to a certain level will be distorted, or shot, “ ” non recording in various music signal, (of course, but to 12 points for the test volume safety standards). Specifically, if orchestral music is one of the favorite types of music, it must pass through the. To a certain extent, the standard speaker can make the sound out of the box to create a clear sound field and image, showing the location and texture of different musical instruments. There are plenty of diffusion that can satisfy the existing listening space, piano and tail should be clearly heard, and in large volume and large “ &rdquo without bursting; distortion, vocal and instrumental sound not inextricably. The quality of the play can show a rich sense of music and the air and the sound of the sound of the ball, like the clouds to see the same as the sky, showing the whole fine and orderly audio and video. And the more immediate is not to be tired of listening to a long time.
