Problems solved by technology

[0004] Some of the existing sound insulation rooms are brick-concrete structures, some are gypsum board structures, and some are made of color steel plates fixedly connected. Although some are welded or spliced ​​by metal plates, their structures are unreasonable and not easy to be flexible. Assembly, the gap between modules is not handled well, and the sound insulation of the sound insulation module, sound insulation door or sound insulation window is not enough, which reduces the overall sound insulation of the sound insulation room. The common defect is that it is not easy to disassemble. Reassembly, or the sound insulation of the sound insulation room is affected after reassembly

Embodiment 1

[0048] Such as figure 1 As shown, a voice recording studio used for radio and television, network education, university language teaching and research or rehabilitation training for deaf children, the size is 3m (length) * 2m (width) * 2.5m (height), install a 1m (width )*2m (height) 43 decibel soundproof door, a 800mm (width)*600mm (height) soundproof window, install ventilation and lighting system, require indoor and outdoor sound level difference to be 40dB(A).

[0049] The bottom panel is composed of three sound insulation modules of 1m (width)*2m (length) connected sequentially through H-shaped steel connectors 3 . The metal plate is a 3mm thick steel plate, the sound insulation material is three layers of commercially available damping plates, the damping layer is commercially available damping glue, the sound absorption material layer is 50mm thick environmentally friendly glass wool, and the total thickness of the sound insulation module is 100mm. When the sound insul...

Embodiment 2

[0057] As shown in the figure, a two-station measurement room installed in an industrial plant for measuring motor noise, the size is 3m (length) * 2m (width) * 2.5m (height), and one installation is 1m (width)* 2m (height) 43 decibel sound insulation door, a 800mm (width) * 600mm (height) sound insulation window, install ventilation and lighting system, require indoor and outdoor sound level difference to be 50dB (A).

[0058] Due to the high environmental noise and mechanical vibration noise in the factory building, it is necessary to use a spring and flat rubber combination vibration isolator. The sound insulation-sound absorption module 2 is used for the facade panel and top panel of the sound insulation room, which has a sound insulation capacity of 45 decibels. The sound insulation room is placed in a corner of the workshop, two sides are against the wall, and the other two sides are separated by 300m, and an outer facade panel with two walls is installed. Each side is c...

Abstract

The invention relates to an assembled metal sound insulation chamber which is used for acoustic measurement of electronic, mechanical and medical products or used as a recording studio, an audiometric room, a laboratory or a control room. The assembled metal sound insulation chamber is characterized in that a sound insulation module and an H-shaped steel connector are inserted together to form a bottom panel; the sound insulation module or a sound insulation-sound absorption module and the H-shaped steel connector are inserted together to form vertical panels and a top panel; all panels compose a metal sound insulation chamber by the connecting and fixing of a C-shaped steel connector, an F-shaped steel, an angle steel and an angle post connector; when the vertical panel and the top panel are sound insulation modules, the internal surface of the sound insulation chamber is provided with a layer of metal sound-absorption module, a vibration isolator is arranged below the bottom panel; and a sound insulation door and a sound insulation window are arranged on the vertical panel and a ventilation muffler is arranged on the vertical panel or the top panel. Owning to the assembled structure, the assembled metal sound insulation chamber is convenient for production, transportation and assembly, has good effects for vibration isolation, sound insulation, ventilation and observation, beautiful appearance, firmness and durability, is environment-protective, has no smells, has the background noise less than 20dB and does not affect the acoustic characteristic after being re-assembled in different places.

Description

technical field [0001] The invention relates to a sound insulation room, in particular to an assembled metal sound insulation room. Background technique [0002] The soundproof room is an acoustic room that requires good airtight performance and acoustic characteristics. It is used for acoustic measurement of products such as electronics, machinery, and medical equipment. It can be used as a language recording room, live broadcast room, medical audiometry diagnosis room, workshop control room or Noise measurement room. [0003] The transmission of noise mainly includes two ways, one is the air transmission way, and the other is the solid transmission way. The general working environment noise range is 45-80dB(A), and the background noise range required for measurement is usually 18-35dB(A). Due to the existence of this noise difference, it is necessary to place the measured object in the measurement room Put it into a specially prepared quiet space for measurement, such as...
