1. Bass part
The bass effect of the speaker can be said to be a very important part of the overall sound quality. It is directly related to the fullness and shocking effect of the sound effect. For speakers, bass is used. The performance requirements of the unit are therefore tested as follows
Put a glass of water next to the speaker. A speaker with a good bass effect can cause the water glass to vibrate, causing ripples in the water glass. A speaker with a better bass effect , the effect is more obvious and lasts longer.
PS: The more realistic the sound effects of weapons and explosions, the better the shock effect
2. Midrange part
The midrange part is suitable for most speaker products Generally speaking, it is more difficult to distinguish the quality of its sound. And its main function is to produce a sense of reality. The test of the midrange part is to watch a multi-channel movie (PS: the kind where two sounds are played together)
3. The treble part
The treble effects of speakers are generally very intuitive. For example, singing and some special electronic sound effects, and even some extreme sounds that exceed the hearing range. Faced with how to conduct this test, the editor's method is to use some high-pitched human voices to feel it, such as Vista's CD
4. Software audition:
First Step 1: Download the audio 100 audio tester audio signal generator software.
The second step is to set up the software, click Settings, select the number of plays, then select the items to be tested in the test list, click "Play" to test.
The third step is to test the 1khz positive wave to determine whether the band is normal (that is, whether it can be played normally, the same below). Usually the parameters given in audio equipment are below 1khz. So click to test first.
The fourth step is to test the low frequency. The low frequencies are mainly 25hz, 31.5hz, 40hz, 50hz, and 63hz. These are the playback limits of many speakers. If the speaker suddenly converges in the selected low frequency, This means that the reproduction limit of the speaker is the low frequency you selected.
The fifth step is more important, which is the test from 80 to 160hz. This test can determine the upper frequency limit of the audio subwoofer. The sound at the frequency is mainly the thick feeling of the music. Even if the sound performs well at this frequency, the sound will not lack bass if the test of the next step is unsatisfactory. On the contrary, it is weak.
The sixth step is the 300~500hz test. The purpose of this test is to test the thickness and strength of the human voice. At this time, if the effect is good, it means the human voice is loud and clear. If the performance is not good, the sound will be loud and clear. Thin and turbid.
The seventh step, 2~4khz test, the purpose of this test is to check the level of music, and generally it should not be attenuated. The important thing to note in this paragraph is that 4khz should not be prominent, otherwise the girl's sibilance will be too strong.
The eighth step, 3~5khz test, the purpose of this test is to test the dividing point between the tweeter unit and the bass crossover of the two-way speaker, commonly known as the crossover point. If the fluctuations in this frequency band are too large, there is a problem with the crossover adjustment.
The ninth step is to test the 8~12khz treble area. The test in this ascending section is a test of the speaker’s level and color appeal and vitality. If the playback effect is good, then the above mentioned The expression effect will be good.
The tenth step is the test of 16~20khz. Many speakers cannot play this band and will show no sound. It is also possible that you are old. If you lack this band, the sound will lack nobility.
Step 11: Positive wave scanning, through which you can quickly determine where the frequency problem is.
