What are the aspects of sound quality evaluation.Big sound bar sales

　　Sound quality evaluation can be carried out from several aspects, namely, brightness, fullness, clarity, balance, softness, strength, realism and three-dimensionality.

　　1. Brightness

　　The high and midrange are adequate, and the listening experience is clear and active. A bad system will sound dim.

　　2. Fullness

　　Sufficient mid and bass, moderate treble, appropriate loudness, moderate reverberation, warm, comfortable and flexible listening. A poor system will sound thin and dry.

　　3. Clarity

　　The language has a high degree of restoration, and the band has a clear hierarchy and a sense of clarity. A poor system has an unbalanced sense of hearing.

　　4 Softness

　　The sound spreads well, the slack is not tight, the treble is not piercing, and the hearing is pleasant and comfortable. A poor system is hard to hear.

　　5 strength

　　The sound is solid and powerful, it can be produced, and it can be dynamically transformed with the sound source. A poor system has insufficient sound power and can't get out, and the dynamic range is compressed.

　　6. Reality

　　Can keep the original sound and hold point. Poor systems have unrealistic hearing, distortion, sound staining, explosions, cracks, and tremors.

　　7. Three-dimensional

　　Sound spatial sense, accurate sound image positioning, continuous sound image group distribution, suitable for recording width and depth. Poor systems have drifted positioning, lacking a sense of depth and improper width of the sound field.

　　8. Balance

　　There are certain scales for the high, medium, and low of the sound. If the rhythm of either side is not particularly prominent, then the system is balanced.

　　Sound quality evaluation terms are based on listening perception, using some specific visual vocabulary to express the sound heard
