Good design of HI-END audio and video can not do not disturb neighbors

Let's talk about another principled statement: the charm of the body's feeling of sound is divided into two types: one through the ear, one through the body (the shock is from the feeling of the body feeling low frequency + audible low frequency together) ), and the small unit inside the TV, the limitation of the vocal area, there is no way to send the frequency of the low frequency band, because of the quality relationship, when the whisper is not clear, the sound will be louder and louder, and then the louder is not louder. It feels that because the low frequency of the small unit is rolling off, the sound gradually increases and the low frequency rise is limited. In fact, using the small unit on the TV, driving to the loudest, the first thing people can't stand watching is the TV, not the neighbor, because the high, medium and low 3 frequency imbalance and distortion cause the consequences of the ears not adapting, because most of them from the balcony The intermediate frequency and high-frequency energy transmitted by the door slits were originally small. After the external daytime 50-60 decibels of ambient sound concealing effect, the neighbors could not hear anything. As mentioned above, it will be passed to the neighbor's house when the night is quiet.

Let's talk about the problem of video and audio interference: it is actually caused by high-powered audio, unit and subwoofer - because the system distortion makes the sound unclear and the low-frequency energy is too big is the main reason for disturbing the neighbor. To solve the problem, we must first analyze the principle, and the right medicine is right.

A. Analyze the principle that the sound is unclear:
In a confined space, the distortion of the overall system is too large, and the sound is disturbed due to poor reflection sound interference, resulting in unclear speech. The average person, making a loud sound - increasing the direct sound allows the sound to overshadow the reflected sound to achieve clear purpose. Real HIEND quality equipment, in the moderate volume, you can listen to very clear, and have a wealth of sound details, naturally do not need too much sound.
B, the subwoofer energy is too large:
The lower the frequency energy, the more 99% of all domestic houses are concrete and brick houses. To feel good sound, the sound pressure level should reach 90db or more (independent video room should reach 100-105db), and the sense of hearing and body. , will feel in place, then the sound insulation value of 40db or more is necessary, 24 cm of the brick wall of the partition according to the specification, can be separated by an average of 40db of sound insulation, and the sound insulation coefficient of all materials is a curve rather than a straight line, 24 The public partition wall can be separated by 50db in 1Khz, and can only be separated by 35db in 100hz. Therefore, the control and processing of low-frequency sound volume is the key to not disturbing the neighbors.

Based on the above two principles: the equipment that should be selected and how to deal with the environment has a direction
1, [select equipment]
Choose a clear equipment package that listens in the (closed) space regardless of the loud volume to the small volume. (Note: Be sure to check the environment, because some equipment is sold in the hypermarket, there is no interference from the reflected sound, so the sound is still clear. You can't judge, and the soundproofing of a closed house is good, so you won't be noisy neighbors. Therefore, you can choose a low-distortion device in a closed room. If you are in a small confined space, you can't hear clearly. The bigger the home, the more you want to follow the design style of the design company, and you don't want to destroy it. In this way, the small volume of the night and the quiet to the appropriate volume of the sense of body, will be clear.
2, [subwoofer selection and processing]
Listening to the bass and massage your chest and abdomen, the feeling of the legs and feet is a powerful sound, the low frequency of the listening is clear and layered, like the real instrument sound, is the good bass, no matter the volume, A small volume will feel comfortable. If you can't hear the bass, you will have a standing wave. If you don't know clearly, you will want to open a loud voice and listen to the clear impulse. Most of the subwoofers are grounded. The insulation from the ground is mostly rubber pad. The direct low-frequency vibration will be transmitted to the ground. Because of the solid sound transmission principle and the relatively weak relationship between the floor and the floor, the influence on the downstairs neighbors is relatively large. Choosing a good subwoofer, plus a blast pad that is compatible with the principle of isolation, can achieve the ultimate day of no interference.
Then, finally returning to the title, why should the quality of HIEND not be disturbed, what can be proved:
Everyone knows that Hong Kong and Taiwan are places where the locals are thick and thick, and they are the places where Chinese enthusiasts gather the most, but few people have the conditions to do audio-visual rooms and acoustics, but why are they placed in the living room, they will not Was complained about disturbing neighbors? Because the audio equipment they use is low-distortion international good sound, the sound is clear at the appropriate volume, the low frequency has a level, and there is no standing wave.

The US KSP HI-END level panoramic sound system solves the above problems very well:
1. The system has small distortion. The HI-END cinema speaker has excellent response speed and balanced high and low frequency. The sound is stereoscopic and realistic, and the flow enveloping is combined with high-end audio-visual effects, which greatly enhances the shock of the viewing experience.
2, the United States KSP HI-END cinema subwoofer and KSP panoramic sound amplifier fully matched circuit design, making the low frequency fast and powerful, feel clean and flexible.
3, the United States KSP HI-END level panoramic sound system, because of the low demand for sound absorption, you can use more inorganic anti-mildew materials can be simple, can be luxurious, high degree of freedom. You can enjoy music, concerts, and movies that are in place to give you a balanced, high-quality lifestyle.
