【 Weak current College 】 how to identify the speaker sound?---Power By 【 China power house network 】


Although any speaker has its strengths and weaknesses, especially in the limited budget, cheap speakers and not easy to get perfect results, but whether any price and level of the speakers, there is some reference standards or reference direction.

1. the quality of the test frequency

Poor quality speakers produce low-frequency can be the detonation of the ear if deaf, but exactly that kind of bloated loose thick, layered and sturdy feel. Better low-frequency should be clean and crisp, structured, does not slip men dying, even if a variety of low-frequency as musical instruments such as the size of the drum, bass guitar and piano, bass, and can easily distinguish between them. So don't be the low-frequency quantities are deceived, poor low frequency sounds as clean natural comfortable.

2. the testing of intermediate frequency of the human voice

The human voice is the most often heard on the merits of sound, and it is not difficult to detect, monitor voice if there is unusual in the nasal or be sipped mouth audible senses. Some speakers sound "box" will significantly interfere with the intermediate frequency, so that the voice of the band Blur. Intermediate frequency bass frequencies relative to the other, more serious bass, as most of you can hear the sound frequency, or the music of frequency are concentrated in the frequency range, this point almost all kinds of music, will be replayed.

3. the test are high frequency of flexible

Poor quality of high-frequency is shrill plug ears, hear a splitting headache, extreme situations violin or soprano of the Bel Canto to brake sharp noise. Similarly, the pitch of a more different instrumental music produces a different texture, good treble is recognizable. Quality level high frequency again or even people to distinguish between two different years in different wood of the out of different phonology. The most readily available to summary is that good treble is not to make peoplelisten and ferocious, pores, nor does it make people listen, the more tired, but this is Mian-tough and flexible, with young slip to the highest level, can still be easily heard but does not produce the sound change (of course not going to do the recording of the sound recording artist)

4. test the high volume and sound field-like

Some speakers in low volume performance stability, but improving the volume to an index will be distorted, or "take sides", a variety of non-recording of the musical signal, (of course, to the volume of 12 points, however, for safety test standards). Specifically, if the Orchestra is one of the favorite genres, you must pass through this gateway. Standard speakers to a certain extent do sound off-box, creating a clear sound field and knot like, showed different musical instruments points location and texture, there is plenty of proliferation and growth, wide, high but ° audio space. Weak tone and be over system should be clearly heard, and in large volume, and the "big tent" no distortion, deformation of the human voice and instrument does not tangle points. The replay can show good quality plump music sense and sense the air, and notes of spring, like the clouds to see the blue sky, showing the whole careful and orderly audiovisual. And more direct is in permanent hearing next not ear tired.
