The sound insulation and noise suppression laboratory is a device for product noise testing under sound insulation conditions, which can provide a quiet space for testing equipment such as precision instruments, transformers, frequency converters, etc. It is 80 decibels outside the room and 20±1 decibels in the room, and has the characteristics of waterproof, fireproof and stable.
Sound insulation and noise suppression laboratory use:
Standard laboratories for testing noise of various products such as (washing machines, electric fans, air conditioners, refrigerators, other electronic and electromechanical products testing/acoustic testing of various home appliances.
Features of soundproof and noise room:
1) Assembly structure of all-metal, external and internal-absorbing sound insulation panels;
2) Adopt damping elastic greedy composite shock absorber, with low natural frequency and good vibration isolation effect;
3) Adopt low-sound axial flow fan, disc type exhaust muffler and sound insulation wall panel with built-in fresh air muffler channel, taking into account the indoor air circulation and acoustic effect;
4) Fire prevention and escape design such as emergency lighting and escape passages;
5) It can realize rapid and repeated loading and unloading, which is suitable for various conditions.
Sound insulation and noise room structure:
1) The main structure of the soundproof room is an anti-vibration frame type, which is assembled by modules, which is convenient for installation and disassembly;
2) The main body adopts square steel as the skeleton, the outer plate is made of environmentally friendly high-quality glass steel plate, the inner side is made of porous aluminum plate, and the high-quality sound-absorbing cotton, sound insulation material and damping paint are used to effectively absorb noise and improve the noise reduction effect of low-frequency noise;
3) The closed joint surfaces of doors and windows are sealed with sealing strips; the seams outside the soundproof room are crimped by aluminum alloy strips, which are beautiful and practical as a whole:
4) The soundproof room is a pentahedron, surrounded by the feeding surface, the main operation surface, the finished product collection surface and the rear operation surface in sequence. Each surface is equipped with a transparent observation safety and operator access door, which is convenient for observing the working condition of the punch;
5) Lifting doors are installed on the collection surface of the finished products of the soundproof room, which are made of light materials, and are driven by motor, mechanical transmission, and chain protection of lifting actions. Safety protection devices and sound and light alarms are installed to ensure the safety of operators:
6) The roof of the soundproof room is equipped with a pneumatic opening seal, which is convenient for changing the hoisting of the mold;
7) An exhaust system is set up indoors, which cooperates with the exhaust of the suction mechanism of the high-speed punch.
8) The soundproof room lighting adopts explosion-proof and dust-proof fluorescent lamps;
9) Size and material can be selected and matched according to different sound insulation and environmental requirements
10) It can be designed and manufactured according to the technical requirements of customers, and the thickness of the laboratory is 200-500mm.
