With a set of tens of thousands or hundreds of thousands of home theater equipment, people are shocked by the effect of a few thousand yuan after the establishment of the equipment, how to do this home theater? How can this life continue?
In fact, acoustic design is very important for optimal or inexpensive home theater equipment. If the design is not professional, or if there is no professional acoustic design at all, it is very possible to see the results mentioned above. Today, we asked Mao Defang, a senior designer of Hesheng Video, to talk about the inappropriate measures commonly used in the design process of home theater. The main points are the problems of audiovisual space conditions and how to solve them one by one.
Size and proportion of the listening environment
Speaking of the listening environment, Mao Defang said that the best shape of the listening environment is rectangular, and the optimal area is about 18-40 square meters. The ratio of height, width and length of the room is preferably in accordance with the golden rule, such as 1:1.25:1.6, 1:1.6:2.5 or 1:2.5:3.2. The size of the square or one side is just twice the room on the other side, the room is too high, and it is not suitable for the audio-visual room. If you must use such a space for the audio-visual room, you can improve the room size by adding, adjusting the ceiling, adding the wall panel, and making the wall panel. At present, it is very common to use wooden cabinets or wooden boards to form compartments, and to transform the length, width and height of the audio-visual room into ideal conditions for the best results.
Sound absorbing material
In general, thicker sound absorbing materials are good for absorbing low frequency sounds, and thinner materials are good for absorbing high frequencies.
Carpet is the most common sound absorbing material. The carpet has obvious absorption effect on the intermediate frequency and medium and high frequency, and has little effect on the absorption of low frequency. If the area is too large when the carpet is set, the details of the sound will be lost. Hanging curtains and hollow slabs are also common sound absorbing materials. In addition to the sound absorbing function, the curtain can also prevent partial sound transmission. The thicker the curtain, the louder the volume. The more the wrinkles and the larger the unfolded area, the more pronounced the sound absorption of the curtain. The roots have different requirements for listening, and adjust the degree of expansion of the curtain to control the absorption of high-IF sound. Hollow slab refers to all kinds of siding, wooden floor with grid, furniture placed indoors, can play the role of absorbing medium and low frequency components.
