6 Key Points for Identifying Car Audio Sound Quality and Methods to Improve It

A. Ambience: Good sound quality has a great sense of space, giving an overall realistic feeling. The best way to describe good sound quality is with the phrase "being there."

B. Loudness: In terms of loudness, good sound quality sounds appropriate and comfortable. A special reminder: when identifying sound quality, you should choose excellent audio sources as test listening material, and selecting content you are familiar with for testing is more advantageous.

C. Clarity: Beautiful sound quality has very clear layers and good transparency, where every word can be heard clearly.

D. Intimacy: This is what people usually refer to as being lifelike, meaning that the sound heard conveys a sense of communication and confession. With general or very poor sound quality, this effect cannot be experienced, which will make you feel tense and distant.

E. Fullness: Adequate mid and low tones, moderate high tones, with warmth and comfort, and elasticity. If the reverberation time is too short, especially if the low-frequency segment's reverberation time is shorter than the mid-frequency segment, its fullness won't be very good. Poor output frequency characteristics of the audio system, lacking mid-low tones, makes the sound seem dry and weak, and it cannot be considered full.

F. Balance: Refers to the proportional coordination of output power between left and right speakers, main speakers and auxiliary speakers, and the correctness of phase. Stereo has good consistency in left and right channels, and the sound image is normal. If the sound image sometimes shifts and lacks coordination, then it cannot be considered good sound quality.

Methods to Improve Car Audio Sound Quality:

When building an audio system, the combination of various equipment should maintain a basically consistent style; otherwise, it may cause inconsistencies in appearance, function, use, and indicators.

A. High Power without Distortion: If using the host to directly drive the speaker, choose one with high output power. Now, the host output power is generally 4×50W, mainly to reduce distortion. If using the front output of the host, choose one with high output level, aiming to improve the signal-to-noise ratio. The output level is generally 2V, and it is best to choose 4V output. In an audio system, the greater the output power of the host or amplifier, the larger the range of audio linearity they can control, and the stronger their ability to drive the speaker. Small-power amplifiers not only easily cause sound distortion but also lead to the burning of the amplifier or speaker coil, resulting in wasted effort without achieving ideal music effects.

B. CD, MD over VCD, MP3: If used only for playing sound, the host should still choose CD, MD, or DVD. VCD has poorer sound quality and is best avoided; MP3 belongs to a compressed format, even with added sound quality processing circuits, its sound quality is still not as good as CD; DVD's sound quality is close to CD, but overall, it is still not as good as CD; MD's sound quality is similar to CD, but the sound is slightly harder. For CD albums, choose authentic ones, those printed with "DDD" on the disk surface are the best, as these CDs have better sound quality.

C. 24bit over 1bit: When choosing models, look at the frequency response index, without any additional functions that embellish sound quality. On CD album labels sold in audio stores, 20bit and 24bit are noted. Only 20bit and 24bit high-resolution can fully display the music. Ordinary audio systems are mostly 1bit, while high-end audio systems often adopt high bit rates. Only on such machines can the delicacy be fully displayed.

D. Natural Playback Principle: So-called playback refers to the music played having little change from the original music. An important indicator in evaluating sound quality is the smoothness of the frequency response curve. Smoothness refers to the volume levels of each sound domain, if each sound domain's volume is consistent, then the smoothness of the curve is good, the better the smoothness, the better the audio-visual effect.

E. Original Sound over Equalizer: The host should select a model that does not embellish the signal. After the signal is embellished, its waveform becomes distorted, so the music played back is not ideal. The best "original" host should not have graphic equalizers, field effects (such as theaters, squares, broadcasting rooms, etc.). After embellishing the field effect, the original signal changes, losing the original sound quality.
