The general sound system is not able to make the building structure design completely according to its own intention. However, it is necessary for the sound designers to put forward corresponding requirements as far as possible in the case that the project quality requirements are strict and the construction project is part of the reconstruction structure. Let's talk about the related contents of the sound engineering in the building structure to achieve a uniform sound field.
Generally, the concept of sound uniformity is not very clear, and there is not too much consideration in the project. Is it not important? No, very important. Take a simple example: when you go to an entertainment hall, you find that the sound conditions are different everywhere. Some places have beautiful music, and some places seem to have some shortcomings. The sound is erratic. This is the effect of poor uniformity.
In relevant national standards, it is generally required that the deviation of field pressure level test value at each point is less than 2dB.
There should be no obvious defects in the building structure. For example, there should not be too many columns in the room, and the wall should avoid the arc of traps, especially the wall on one side of the stage should not have a large shape structure; It is not allowed to have large sound shadow areas within the sound reinforcement range. However, since a large number of changes cannot be made to meet these requirements after the decoration is completed in the later stage of the construction of the building structure, experience should be used as much as possible in the sound engineering to skillfully arrange the sound reinforcement areas, avoid large defective structures, and reduce their impact to a very low level;
It can timely and effectively provide some simple schemes to the decoration units to improve the sound diffusion effect. For example, all concert halls have good sound diffusion effect, because a large number of sound diffusers of various shapes are used inside, and these structures can be completed by some simple decoration methods.
Therefore, as long as the method is appropriate, it should be able to achieve better results. Of course, it is not easy to design the shape, position and quantity of the diffuser reasonably and properly. Generally, the more economical and feasible method is to use the wall cement roughening method. Although this method seems old and not beautiful, it can play a very effective role in the sound diffusion of the hall.
Shandong audio manufacturers believe that the reasonable layout of the audio system, especially the placement of the speakers, must be strictly required. If the computer design software provided by some speaker manufacturers can be used for sound field simulation in the design, it would be better. If not, it should be adjusted in practice until the sound field is very good.
