Car Audio Identification of sensory quality of six elements: 1, definition. Wonderful sound level is very clear, transparency, and can hear every word clearly. 2, fullness. In the full bass, treble moderate, with warm, comfort, flexibility. If the reverberation time is shorter, especially the low frequency reverberation time was even shorter than in the band, its fullness is not good; output frequency characteristics of the sound system, the lack of bass, so the sound will become shriveled weakness, not to mention also full. 3, kindness. It is usually referred to vivid, that is to hear the voice of the existence of a communication, talk sense. General or the poor sound quality is not experience this effect, it will make you feel urgent and distant. 4, sense of balance. Refers to the left and right speakers, main speakers and auxiliary speaker output power ratio between the coordination and the correct phase. Left and right stereo channel consistency, audio and video properly. If the audio and video sometimes it is not enough coordination of migration, it is not really good sound quality. 5, environmental sense. Sound good sense of space, the whole feeling of real people, using virtual reality to describe the good sound quality is the most fitting. 6, loudness. In loudness, the good quality sound is appropriate and comfortable. Cautions, should be selected in identifying good quality sound source as a source of audition shows, as well as choose their own content to do familiar test is more favorable. Car Audio Quality improvement elements: In establishing sound system, all equipment should be maintained with a consistent style, or may result in the appearance, function, use, indicators such as disharmony. 1, to CD , MD not to VCD, MP3 : If only to play a sound, select the host or CD, MD or DVD. VCD poor sound quality, better not; MP3 is compressed format, although the increase in sound processing circuit, but the sound quality is still not as CD; DVD's sound close to CD, but the overall comparison, not as CD; MD and CD sound quality difference is not , but the sound is slightly hard. CD, to use authentic, printed with the disk "DDD" the best, this CD, produced good sound quality; 2, to be "genuine," not to EQ: the host should be used without any modification of the signal models. After the modified signal, the waveform distortion, so play out music is not ideal. "Genuine," the best host there is no graphic equalizer, field-effect (such as: theater, square, studio, etc.). Effect on the field was modified, the original signal will change, loss of the original sound quality. 3, to 24bit not 1bit: see frequency response indicators for selected models, without any additional modification of the functions of sound quality. Shop selling audio CD, the label 20bit and 24bit. 20bit and 24bit high resolution can the music be fully demonstrated. General Audio mostly 1bit, fever more than high-level audio bit. Only in such a machine to play, and will show the extent of its fine. 4, should not be distorted power: If the host directly promote the speakers, to select high power output. Now the host output power is generally 4 × 50W, mainly to reduce the distortion. If the host of the front output, to select high output level, and aims to improve the signal to noise ratio, output level generally 2V, the best choice for 4V output. In an audio system, the host or the greater the output power amplifier, it shows that they can control the audio greater linear range, then the stronger the ability to drive speakers. And small power amplifier is not only easy on the distortion caused by sound, it will cause burning power amplifier or speaker coil, in the end spent a lot of effort but not good sound effects. 5, sound principles of natural replay: The so-called replay is out playing music and original music changed little. Sound quality evaluation is an important indicator of the smoothness of frequency response curve. Smoothness of the curve is the loud voice of the size of each range, each range are consistent with the sound, like the smoothness of its curve, the better smoothness, audio-visual the better.
