Description
Technical Field
The invention relates to the technical field of building acoustics, in particular to a modularized sound coupling tone quality adjusting wall structure.
Background
With the deep research of sound quality of a performance space, the problem of sound environment of the performers is exposed, wherein the space of a concert hall stage, a theatre pool, a rehearsal hall and the like in a performance area of a symphony band is the most troublesome. In long-term timbre studies, gade considers reverberation time to be only six of the acoustic properties, other acoustic properties such as support, timbre, dynamics, mutual listening and time delay are more important to the performer, so Gade adopts stage support ST measures to evaluate ensemble and late reflected sound quality. And the subsequent Dammerud finds that the stage support degree ST is limited by 10ms and 100ms, the early stage support degree, the late stage support degree and the total stage support degree are distinguished, and the reverberation time T30 is combined, so that the stage tone quality is judged together. The international standard ISO3382-1 uses the research result and uses the ensemble condition and reverberation feeling as recommended indexes of stage sound quality, wherein the early stage support, the late stage support and the total stage support are collectively called as the ensemble condition.
Through further investigation, the problems of sound overdrawing in the performance area, insufficient stage support, difficulty in hearing other players, poor sound quality effect and the like are quite remarkable. For example, a symphony performance in a space such as a concert hall stage, a theatrical pool, and a concert hall requires that the sound parts are balanced with each other and that the sound has a gradation, and particularly, it is necessary to suppress the sound intensity at the time of a percussion performance and to strengthen the sound intensity at the time of a string performance.
To solve the above-mentioned problems, the primary option is to use an acoustic diffuser to attenuate the directionally reflected sound using the diffusion principle. In addition, there is also a method of expanding the area of the playing area to reduce the total acoustic energy of the playing area by natural attenuation of acoustic energy. In recent years, there have also been methods of reducing the total sound energy of the playing area by means of sound absorbing materials. However, the problems with these solutions are apparent. Although the diffuser arrangement can better reduce the directionally reflected acoustic energy, the reduction of the total acoustic energy is not ideal; the way of expanding the playing area can reduce the total sound energy, but the excessive stage size can make the mutual hearing among players difficult, and even there is a risk of generating echo; the way to add sound absorbing material, while reducing the total sound energy, is difficult to meet the needs of various performances. Therefore, the better tone quality adjusting structure is required to weaken the total sound energy of the playing area, effectively optimize the mutual hearing of players and simultaneously meet the requirements of various performance types.
The structure which can play a role in adjusting sound quality in the market at present mainly adopts a mode of compounding a diffusion facing and a sound absorption facing. Three common configurations are provided, one being of the flip type, one being of the lift type and the other being of the pan type. The turnover structures are that a diffusion facing and a sound absorption facing are respectively integrated on two sides of the turnover plate; the lifting type is similar to the translational type in construction, and the diffusion or sound absorption properties of the construction are changed by adjusting the position. However, these constructions are only effective in optimizing the problem of "the performance area sounds are loud" for "it is difficult to hear other players" and "the tone quality effect is poor".

the sound insulation curtain 4 mainly plays a role in reflecting sound energy, is mainly used for matching with the grating strip plates 3 to perform sound energy frequency selection diffusion and adjust the volume of the sound coupling cavity 2, is preferably made of non-sound-absorbing and non-sound-transmitting materials, is vertically arranged in a winding manner, particularly can be made of hard, non-porous, non-sound-absorbing and non-sound-transmitting materials such as PVC, and of course, the number of the sound insulation curtains 4 to be arranged can be freely adjusted according to actual conditions;
the sound absorption curtain 5 mainly plays a role of absorbing sound energy, is mainly used for adjusting the sound absorption quantity of the sound coupling cavity 2 and blocking unfavorable reflected sound, is preferably made of porous sound absorption materials, is vertically arranged in a winding manner, and particularly can be made of porous sound absorption materials such as panne, velvet, corduroy, canvas, microporous glass cloth and the like, if the building fireproof requirement exists, 100% of the fireproof materials can be selected according to the fireproof grade, the discount rate of the sound absorption curtain 5 is between 100% and 200%, and the quantity of the sound absorption curtains 5 which are required to be arranged can be freely adjusted according to actual conditions;
based on the above-mentioned diffusion module, anti-sound module and sound absorption module, the size of acoustic coupling cavity 2 can directly influence a series of tone quality parameters such as acoustic energy intensity, reverberation sense, reflection sound sequence, therefore the size of acoustic coupling cavity 2 that is located diffusion module rear is crucial, simultaneously, considers the size of construction place size and is in order to construction convenience's consideration, acoustic coupling cavity 2's depth is not less than 1m, its width and height are all between 2m ~ 5 m.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
