[0002] When conducting hearing tests, it is necessary to conduct them in a listening room to achieve an ideal testing environment. Depending on the testing method, the acoustic indicators of the listening room must meet the standards and screening requirements. A standard listening room should meet the basic requirements for testing. Currently, the customization of the listening room is done by first measuring and designing the site provided by the user, and then manufacturing multiple soundproof wall panels in a factory that specializes in making soundproofing materials. These panels are then shipped to the user's site, where they are assembled into a soundproof room.

[0003] In existing technologies, such as the modular listening test chamber with publication number CN111663806A, the main body of the listening test chamber is composed of several relatively independent multi-faceted soundproof wall modules. This allows users to combine them according to specific usage needs to obtain the corresponding listening test chamber. Employing a "cut-and-paste" design, the listening test chamber is divided into multiple standard soundproof modules. One or more modules can be combined and spliced ​​together to form a complete listening test chamber according to the actual needs of the user's site. This design offers numerous advantages, including convenient transportation, easy installation, disassembly and reconfiguration, and an aesthetically pleasing appearance.

[0060] Step 4: During disassembly, press the spring insert 106 and spring post 107 to remove the audiometer chamber cover 3 and audiometer chamber insert 2, and then pull out the audiometer chamber base 4 to separate the two positioning seats 103.

[0061] Step 5: After separation, fold the two movable panels 1 of the listening chambers, insert the two insertion plates 2 of the listening chambers into the two movable panels 1 of the listening chambers respectively through the limiting groove 104, limit them through the spring insert 106, then fix the listening chamber cover 3 above the sealing block 402 of the listening chamber base 4 through the limiting clip 301, stack the two movable panels 1 of the listening chambers on top of the listening chamber cover 3 to complete the storage.

[0062] Working principle: During assembly, the two audiometer chamber movable plates 1 are folded up above the positioning seats 103 via the connecting shaft 1031 and then erected. The two sides of the audiometer chamber base 4 are then inserted into the base plate slots 1032, connecting the two positioning seats 103. The positioning blocks 205 of the audiometer chamber insert plates 2 are then inserted between the two limiting blocks 105, and the spring column 107 positions the positioning blocks 205, thus positioning the two audiometer chamber insert plates 2 relative to the two audiometer chamber movable plates 1. After fixing, the listening chamber cover 3 is placed on top of the listening chamber movable plate 1 and the listening chamber insert plate 2. The limiting block 301 is inserted into the limiting groove 104, and the positioning block 3011 is embedded above the positioning insert 205. The listening chamber cover 3 and the listening chamber insert plate 2 are fixed by the spring insert 106 being inserted into the positioning groove 3012. This completes the quick assembly, which is simple in structure and does not require tools for assembly. The protective plate 101 protects the listening chamber movable plate 1 while providing access. The air system, through the electric cylinder 204, allows for the electric adjustment of the movable door panel 202, making the position between the movable door panel 202 and the listening chamber door frame 201 more tightly. The sealing effect is further enhanced by the sealing block 402 and the limiting block 301, facilitating audiometry. During disassembly, the listening chamber cover 3 and listening chamber insert 2 can be removed by pressing the spring insert 106 and spring post 107. Then, by pulling out the listening chamber base 4, the two positioning seats 103 are separated from the listening chamber base 4. Then, the two movable panels 1 of the listening chamber are folded over, and the two insertion plates 2 of the listening chamber are respectively inserted into the two movable panels 1 of the listening chamber through the limiting groove 104. The spring insertion block 106 is used for limiting. Then, the listening chamber cover 3 is fixed above the sealing block 402 of the listening chamber base 4 through the limiting clip 301. The two movable panels 1 of the listening chamber are stacked on top of the listening chamber cover 3 to complete the storage. The four modular combination panels are separated and stacked to reduce the volume occupied by the combination panels and facilitate the storage work.
