A good car sound should have a variety of factors, and the following is to identify the six elements of the sound quality.
1, clarity. Beautiful sound level is very clear, transparent, every word can be heard clearly.
2, fullness. Medium, bass, full membrane, high pitch, membrane, moderate, warm, comfortable and elastic. If reverberation time is short, especially the reverberation time of low frequency segment is shorter than the middle frequency band, the fullness will not be too good. The output frequency characteristic of the audio system is poor.
In the lack of middle and low tone, such a sound will appear dry and weak, not full.
3, intimacy. That's what people usually call "lifelike", that is, there is a communication and a sense of voice in the voice they hear. However, the general or poor sound quality is not aware of this effect, it will make you feel urgent and distant.
4, balance. It refers to the right and left loudspeaker, the proportion of the output power between the main speaker and the auxiliary loudspeaker is coordinated and the phase is correct. The left and right vocal tract of the stereo is good, and the sound and image are normal. If the audio and video are sometimes offset and uncoordinated, it will not be good sound quality.
5, the sense of the environment. The sound sense of the space is good. The whole feeling is true. It is the most appropriate to describe the sound quality with the situation.
6, loudness. In terms of loudness, good sound is sound and comfortable.
