Three methods teach you how to identify the sound quality of speakers.
There is no doubt that any speaker has its strengths and weaknesses, especially most low-cost speakers. Under the limited budget, it is not easy to get perfect results. However, no matter what price and level of speakers, there are certain reference standards or directions involved. Let's talk about how to identify the sound quality of speakers.
1. Test the quality of low frequency: In terms of low frequency performance, the speaker can be better tested. The low frequency produced by poor quality loudspeakers can be loud and deaf, but it is completely bloated, loose and thick, lacking layering and firmness. A good low frequency should be clean and crisp, with distinct levels, without dragging mud and water, and with ghosts lingering. Even the bass of various low frequency instruments such as large and small drums, bass guitar and piano can be easily distinguished. Therefore, don't be fooled by the low-frequency sense of quantity. Low-quality low-frequency sound is not as comfortable as clean sound.
2. Test the mid-frequency human voice: It turns out that human voice is the most frequently heard voice among the voices. It is not difficult to detect the pros and cons. Pay attention to whether human voice has unusual nasal sounds or the feeling of being sipped. The "box sound" of some speakers will also greatly interfere with the intermediate frequency, making the sound in this frequency band indistinct. Intermediate frequency tone dyeing is more serious than other frequency tone dyeing, because most of the audible sound frequencies or music frequencies are concentrated in the intermediate frequency range, which will become an obstacle to replay for almost all kinds of music.
3. Test the flexibility of high frequency: poor quality high frequency is shrill ear insertion, which makes one have a splitting headache. In extreme cases, it changes the beautiful sound of violin or soprano into the sharp noise of brake. In the same way, different instrumental music in high-pitched voice often produces different textures, and good high-pitched voice can be distinguished. For example, it is often said that a good sense of air is the reason why high-pitched and ultra-high-pitched sounds are good.
Summary: Test the speaker from three aspects: high, medium and low frequency. In particular, the performance of low frequency is more difficult to control for loudspeaker production. Each loudspeaker has a certain reference standard or direction. High-quality replay can show rich musical feeling and air feeling, as well as the bounce of notes, and show the whole piece of meticulous and orderly audio and video as if you could see the sky through the clouds. And more directly, it will not make your ears tired after listening for a long time.
