Nowadays, with the rapid promotion of digital technology and the gradual popularization of digital TV, home theater is no longer rare.
Remember what was the most anticipated thing when you came home from school? It is estimated that most people have the same childhood memories as Xiaobian, that is, to open the antique black-and-white TV to see the favorite Wukong three-player bones, or Sanmao wandering, black cat sheriff, etc., then mobile phone Computers, smart players are all far away from us, just when writing technical essays about the future I hope that ten years later - TV opportunities will become colored, radios can be loaded into pockets... These have been dreams Come true, while the progress of the emotional era, more we need to look to the future, how to let us enjoy the higher value of life in our lifetime, is it worthy of the hard work of this life to work hard and solve problems for you.
First of all, how to design an indoor home theater of your own? In order to design an indoor home theater, the most important thing is to understand the influence of the indoor space and the selected materials on the sound field. In the requirements of the indoor environment, we need to use the "standard" body type as much as possible . The traditional "standard" body type should be rectangular, and the rectangular shape is relatively easy to deal with the circular or polygonal sound field. Acoustics The spread is also relatively easy to calculate. On the other hand, we also need to consider the relationship between the acoustic parameters of the indoor sound field and the subjective listening effect, that is, the subjective evaluation of the sound quality. This is also an extremely important link. It can be said that the quality of the indoor sound quality is ultimately determined by the subjective audience. Feeling, due to the differences in the personal feelings and appreciation of the general audience, the inconsistency in subjective evaluation is one of the important links in the performance of indoor sound quality.
Diffusion acoustic treatment, we should consider the diffusion of the environment before the indoor environment to do the sound absorption treatment design. Reasonable diffusion acoustics can make the sound performance more balanced, to improve the uniformity of the direct sound and improve the sound field performance. We can also deal with manual delay, artificial reverberation and other measures through the later equipment adjustment. Combined with the indoor diffusion acoustics treatment has become an important part of the home theater environment, which deserves further study.
Reasonable sound absorption processing, whether it is home theater design or hall design, it involves the sound absorption part, so the application of sound absorption and the application of sound absorbing materials are also very important. Even if there is good indoor sound quality design, if it is seriously disturbed by noise, It will also destroy the entire listening environment. In order to ensure the playing of indoor movies and the normal life of the outside world, it is necessary for us to cut off the sound in the room. On the contrary, if we control the outside world to enter the room, we can have a better viewing environment. interference.
In the solution of noise, we can use some sound-absorbing panels, sound-absorbing cotton or a certain frequency band that uses the resonance principle to cancel the sound, and block the sound bridge, so that the noise of the entire cinema environment is affected by external noise. Noise is to control the noise within an appropriate range according to actual needs and possibilities. For home theater, we also control the noise to a reasonable standard value, and can not be "completely" cut off. The first thing to solve in a quality home theater environment is its noise barrier and the application of acoustic materials. Reasonable calculation and application of building acoustic materials can not only create a comfortable viewing environment, but also make the sound more realistic and natural.
　　 The so-called "the book has its own Yan Ruyu, the book has its own gold house", I believe that reading so much technical knowledge will definitely help you in the actual operation, but practice is the basis of truth, you may wish to try the assembly by hand. A home theater that is unique to you, so that your family and children have a more comfortable rest harbor!
