[0002] In order to ensure the accuracy and reliability of the audiometry results, the hearing test should be carried out in an electro-audiometry room (hearing detection room). Different hearing examinations have different requirements for the environmental noise of the electro-audiometry room (hearing detection room). The construction of the electro-audiometry room (hearing detection room) involves comprehensive technologies of multiple disciplines such as architecture, acoustics, physics and audiology. Different from ordinary decoration, multi-layer sound insulation boards are set as the wall structure and applied to the walls of the sound insulation chamber.

[0003] At present, when the wall structure of the hearing test sound insulation chamber is large in volume, it is inconvenient for workers to carry, and a large amount of manpower and material resources are required to carry the wall structure into the room. While for the wall structure with a small volume, noise will seep out from the joints of the walls, and the sound insulation effect is poor. For the above reasons, it is necessary to design a wall structure that is convenient to carry and does not affect its sound insulation effect. Content of the Utility Model

Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the following will describe the embodiments of the present disclosure more clearly and in detail with reference to the accompanying drawings of the present embodiment. Note: The described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present disclosure.

[0026] As Figure 1 and Figure 2 shown, the wall structure of the hearing test sound insulation chamber provided by the embodiment of the present utility model includes a mounting rack 2 and a plurality of wall panel units 1. The mounting rack 2 and the wall panel units 1 are both connected through a splicing end 3. When installing the sound insulation chamber, the mounting rack 2 is connected to the plurality of wall panel units 1 to construct one wall panel of the sound insulation chamber, and then through the connection between the mounting rack 2 and the main beam of the sound insulation chamber, the installation of the sound insulation chamber is completed; then, an outer sound insulation pad 41 is sleeved outside the mounting rack 2 and the plurality of wall panel units 1 to perform sound insulation wrapping on the outside of the plurality of wall panel units 1, and an inner sound insulation pad 42 sleeved inside the mounting rack 2 and the plurality of wall panel units 1 is used to perform sound insulation wrapping on the inner wall of the sound insulation chamber, realizing the gap sealing between the plurality of wall structures and preventing sound from leaking out through the gaps; then, a plurality of sealing plates 5 are arranged inside the inner sound insulation pad 42, and sound absorption blocks 6 are arranged on the sealing plates 5. By arranging the sound absorption blocks 6 on adjacent two sealing plates 5 vertically, the transverse waves and longitudinal waves generated in the sound insulation chamber can be weakened, realizing the weakening of sound energy and the sound insulation of the inner space of the wall structure.

[0027] Among them, as Figure 2 and 3As shown in the figure, in order to facilitate the handling of the position of the wall panel unit 1, the length of the wall panel unit can be set between 0.9 and 1.5 meters, and the width of the wall panel unit 1 can be set between 0.5 and 1 meter, which is convenient for adult workers to carry the position of the wall structure.

[0028] In order to facilitate the handling of workers, according to the existing production technology of the sound insulation chamber wall panel structure, the wall structure will be pressed into a single board with materials such as sound-absorbing cotton board, iron layer sound insulation board, sound insulation keel, and polyethylene protective film. The wall panel unit 1 includes a packaging box 11, a board body 12 is arranged in the middle of the packaging box 11, and a packaging cover 13 is arranged at the opening of the packaging box 11. Therefore, in this embodiment, by setting the existing wall structure into the structure of the board body 12, and through the set of the board body 12 structure inside the packaging box 11, a protective structure outside the wall structure can be added to seal the side wall of the board body 12. Then, through the sealing of the packaging cover 13 at the opening of the packaging box 11, the board body 12 can be sealed in the packaging box 11 to realize the integrated connection of the wall panel unit 1, enhance the sound insulation effect of the wall unit 1, and increase the structural stability of the wall structure.

[0029] For better sound insulation effect of the wall structure, when selecting the outer sound insulation pad 41 and the inner sound insulation pad 42, both structures can use sound insulation felt materials. Utilizing the advantages of the sound insulation felt being light in weight, ultra-thin, soft, and having a large tensile strength, it is convenient for workers to flexibly cut the sizes of the inner and outer sound insulation pads 41 and facilitate their installation positions; and it is convenient for the outer sound insulation felt and the inner sound insulation felt to cover both sides of the wall structure. Through the shape change of the sound insulation felt coil, it is convenient for the inner sound insulation pad 42 and the outer sound insulation pad 41 to cover the outside of multiple wall panel units 1 and overlap and cover the connection between the wall structure and the mounting frame 2 to avoid the leakage of sound from the gaps in the wall structure and improve the sound insulation effect between the wall structures.

[0030] Furthermore, in order to facilitate the quick installation of the outer sound insulation pad 41 and the inner sound insulation pad 42 with the wall panel unit 1, as Figure 3 shown, an adhesive layer 43 can be arranged on one side of the two structures close to the wall panel unit 1. Through the adhesion of the adhesive to the wall panel unit 1, the outer sound insulation pad 41 and the inner sound insulation pad 42 can be fixed, and the connection of the outer sound insulation pad 41 and the inner sound insulation pad 42 with multiple wall structures can be completed, increasing the installation convenience of the wall structure and facilitating the adhesion with multiple wall panel units 1.

[0031] For better sound insulation effect, in some embodiments, the blocking board 5 can use wood materials, such as Figure 4As shown, the plugging board 5 is made of wood material. There is a same pneumatic nail 51 between the plugging board 5, the inner sound insulation pad 42 and the wallboard unit 1. Through the setting of the plugging board 5, not only can the gaps at the joints of multiple wallboard units 1 be plugged, but also the pneumatic nail gun used during the installation of the sound insulation room can be used to nail the plugging board 5 and the inner sound insulation pad 42 to the wallboard unit 1, increasing the structural firmness and installation convenience of the wallboard unit 1, facilitating the connection between the sound absorption block 6 and the plugging board 5, and improving the sound insulation effect on the inner side of the wallboard unit 1.

[0032] To facilitate the connection between the sound absorption block 6 and the plugging board 5, as Figure 5 shown, a cross slot 52 is opened on the plugging board 5. A horizontal plate 53 and a vertical plate 54 that penetrate each other are clamped in the cross slot 52, and the horizontal plate 53 is fixedly connected to the sound absorption block 6. When connecting the sound absorption block 6 and the plugging board 5, the horizontal plate 53 and the vertical plate 54 are used to penetrate the cross slot 52 on the plugging board 5 at the same time to realize the splicing use of the limiting block and the plugging board 5. The vertical plate 54 is used for the up and down locking of the sound absorption block 6, and the horizontal plate 53 is used for the front and back locking of the sound absorption block 6. The horizontal plate 53 and the vertical plate 54 slide into the plugging board 5 through the cross slot 52, facilitating the disassembly and installation of the two structures and increasing the installation firmness of the sound absorption block 6 on the plugging board 5.

[0033] For better sound insulation effect and to weaken the transmission of internal sound to the outside, as Figure 5 shown, the sound absorption block 6 can be set into a right trapezoid structure, and the acute angle end of the sound absorption block 6 is set outward, and the sound absorption block 6 is made of sound absorption cotton material. Through the setting of the position of the acute angle end, it is convenient to cut the sound generated during the hearing test in the sound insulation room. The multiple groups of sound absorption blocks 6 distributed horizontally and vertically can not only weaken the transverse wave in the sound, but also weaken the longitudinal wave in the sound, realizing multi-directional sound insulation of the sound. And when two sound absorption blocks 6 are distributed oppositely, they form a rectangular structure, which is convenient for the installation of the sound absorption block 6 in different directions, saving installation time and increasing installation convenience; and during the production of the sound absorption block 6, this structure can reduce the waste of materials.

[0034] Working principle: When the wall structure in this embodiment is applied in a sound insulation room, wallboard units 1 of appropriate specifications will be assembled according to the size of the sound insulation room to be built. Among them, the sound insulation room will first use main beams to fix the positions of the mounting brackets 2, and then through the use of wall units and the splicing ends 3 on the mounting brackets 2, multiple wallboard units 1 can be used to form one side wall of the sound insulation room. Then, an inner sound insulation felt is covered on the inner side of this wall, and an outer sound insulation felt is covered on the outer side of this wall. Then, the sound absorption blocks 6 are spliced with the blocking plates 5 by using the horizontal plate 53 and the vertical plate 54 to penetrate through the cross grooves 52 on the blocking plates 5 at the same time. Then, multiple blocking plates 5 are sequentially fixed on the inner sound insulation pads 42 to block the gaps between multiple wallboard units 1 to prevent the leakage of sound; and the sound absorption blocks 6 on multiple blocking plates 5 are vertically distributed to weaken the energy of the sound generated in the sound insulation room and improve the sound insulation effect of the sound insulation room.

[0035] Of course, the above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
