The ability to regulate and balance tone

A good speaker should strive to accurately and completely reproduce the original attributes and characteristics of the instrument and sound. Perhaps sometimes this is reflected in the accurate tone balance function. The sound should give a smooth and unadorned feeling, without any obvious distortion in tone coloring or high pitch depiction. The middle and high tones do not have a particularly empty or oppressive feeling.

Check the characteristics of individual phonemes in the speaker

In the tone balance test, if the speaker performs well and the coherence of the entire speaker is good, then the next step is to test the individual phoneme characteristics, including resolution. Listen carefully to certain details of music, such as piano notes or the lingering sounds of cymbals. If the delicate details appear blurry, then this speaker lacks clarity. The details of the slender parts are important reference data for testing the realism and authenticity of the speaker. deep

How to distinguish the sound quality of a speaker is a headache for buyers. The following are the six elements of distinguishing sound quality that the editor has summarized for everyone.

1. Clarity. The beautiful sound quality has a very clear hierarchy, good transparency, and every word can be heard clearly.

2. Fullness. The middle and low tones are full, the high tones are moderate, warm, comfortable, and elastic. If the reverberation time is relatively short, especially in the low-frequency range, the reverberation time is even shorter than in the mid frequency range, its richness will not be too good; The output frequency characteristics of the sound system are poor, lacking mid to low tones, which can make the sound appear dry, weak, and not full.

3. A sense of familiarity. It is what most people call lifelike, which means that the sound they hear has a sense of communication and pouring out. And ordinary or poor sound quality cannot understand this effect, it will make you feel urgent and distant.

4. Sense of balance. It refers to the correct proportion and phase of the output power between the left and right speakers, the main speaker, and the auxiliary speakers. The consistency of the left and right channels of stereo sound is good, and the sound image is normal. If the sound and image sometimes have deviation and cannot be harmonious, then it is not considered good sound quality.

5. Environmental sense. The sound has a good sense of space and gives a realistic feeling. It is most appropriate to describe good sound quality as being in person.

6. Loudness. In terms of loudness, good sound quality sounds appropriate and comfortable.
