Answer:When there is no comparison, ordinary people are really hard to tell the sound quality is good or bad, but as long as the actual audition and comparison, and then understand some simple audio knowledge, it is easy to hear the sound quality. Under normal circumstances, the more expensive audio, the sound quality will be better. Scientifically speaking, there are three main factors that determine the sound quality, lower distortion, wide and flat frequency response, and a more realistic and enveloping sound field. The degree of distortion depends on the audio link consisting of 5 links of program source (CD, Blu-ray, MP3, lossless audio files, etc.), decoder, power amplifier, cable, and audio unit, which is the shortest board, that is, distortion The link with the greatest intensity affects the final sound quality. In the first four links, under current technological conditions, the distortion can reach less than 1%~0.01% or even 0.001%. In the last link, the distortion of the audio unit is less than 5% for good brands and less than 5% for best brands. 0.5~2%, ordinary brands will even exceed 10~15%. The average person can clearly hear the difference in distortion, at around 2%, a true audiophile can easily hear less than 0.1% of the distortion. Therefore, the difference in audio unit is the biggest factor affecting sound quality. CIC Audio®'s 700 series and 900 series speakers use monitor-grade audio units with ultra-low distortion and can accurately restore the essence of the sound. , Can be used as a measure of the sound quality of different audio standards.
Answer:Before understanding tone consistency, we first need to understand what tone is. Tone color is the color of the sound, not the volume or pitch, but the harmonics other than the fundamental wave in the sound. Two people sing, the pitch and volume are the same, but the difference is the difference in timbre. The piano, erhu, violin, saxophone and other instruments have the same pitch and volume, but it is easy to hear different instruments because of them. The sound is different. In the sound system, different tones are produced by different sound unit materials and structures. In a stereo sound system, the sound units of the left and right channels are different, which will cause interference distortion of different sound harmonics, resulting in deterioration of sound quality. In a surround sound system, the front left, center and right main channel audio units should be of the same material, model or even batch to ensure that there is no distortion. For surround channels, at least ensure that the midrange and woofer are consistent with the main channel to avoid distortion. In a space or a set of sound systems, all sound channels use sound units with consistent timbre, which is timbre consistency. Different series of CIC Audio®, in order to achieve different tones and meet different listening needs, the materials and structures of the audio units used will be different. But in the same series, the woofer and tweeter are the same material and structure, and have the same tone. In the same space and sound system, using the same series of CIC Audio® products, it also achieves tone consistency.
Answer:Different speaker types, if you use the same series, there will be no difference in sound quality. For example, the sound quality of CIC Audio®'s 500 series of ceiling, wall, pendulum and wall speakers is the same in a standard acoustic environment. The cabinet of the speaker, including open, closed, inverted and passive, essentially isolates the inverted sound wave of the unit. If the unit size is smaller, or more low-frequency dives are required (to cater to Consumers who like more subwoofers) usually adopt the inverted or passive type. If the pursuit of sound accuracy and speed, they usually adopt closed and open types. Ceiling and in-wall speakers are open speaker structures. If the cavity on the top of the ceiling and the wall is large or even connected to other rooms, it is necessary to add a back box on the back of the open box to form a closed box. Therefore, as long as it is the same series of CIC Audio®, different speaker types are just to match different installation conditions, and there will be no obvious difference in sound quality. There is also a traditional misunderstanding: Bookshelf type and floor-standing speakers, the role of the cabinet, can achieve resonance with the unit, the larger the cabinet volume, or the higher the cabinet material, the better the sound quality— -This view is very wrong. For some musical instruments, such as the violin, the vibration of the strings drives the resonance of the body cavity, and the principle of sound generation is different from the principle that the vibration of the speaker unit drives the air to vibrate. It is emphasized again that the cabinet of the sound box only isolates the anti-phase sound wave, avoiding the superposition of the positive phase sound wave to form a phase cancellation, causing sound distortion, and cannot improve the sound quality itself.
Answer:The power of the speaker includes three, minimum power, rated power and peak power. As long as the power of the power amplifier is greater than the minimum power of the speaker, the two can work normally. For example, CIC Audio® 300 series ceiling speaker IC-6, the minimum power is 10W, the maximum power (peak power) is 150W, and the rated power is about 75W (usually half of the peak power). If the single channel power of a 300-IC-6 power amplifier is greater than 10W, it can work normally, and the rated power of the power amplifier is greater than or equal to 75W, and the performance of the speaker can be fully utilized. Therefore, our matching CIC-AVR-729 surround sound AV power amplifier, with a rated power of 85W per channel, can perfectly match all types of speakers of the 100 series, 300 series, 500 series and 700 series. Is the greater the power of speakers and amplifiers, the better? The answer depends on another parameter: sound pressure level. The sound intensity in a space is the sound pressure level, and the unit is dB (SPL). Under normal circumstances, the lowest sound pressure level that can be heard by the human ear is 10dB, soft talk in the room is 40dB, the sweet music in the living room is 60dB, the noisy street is 80dB, the explosion scene played in the movie theater is 100dB, and the plane on the airport The take-off and landing is 120dB. Therefore, whether it is playing music, watching TV programs, or even watching large movies at home, the maximum sound pressure level will not exceed 105dB. In the case of CIC Audio® speakers and power amplifier products, the maximum sound pressure level can even reach 105dB (THX standard) when the rated power is matched, but it is rarely used in actual use and usually adjust the volume Turn the knob to 50~80dB.
Answer:Most of the audio brands that people have heard of are car audio brands, sound reinforcement brands or external Hi-Fi audio brands, such as Harman Kardon (car audio), JBL (sound reinforcement, KTV audio), BOSE (car Audio, sound reinforcement), YAMAHA (musical instruments, sound reinforcement, KTV audio), B&W (car audio, Hi-Fi audio) and Berlin Voice (main car audio, Hi-Fi secondary), etc., because these brands are in life Easy to see in.
