Zhongke Kingda specializes in measurement and control research in the field of industrial control. In terms of acoustic measurement and control, we provide customers with a series of solutions for product acoustic performance testing and product research and development acoustic evaluation, including semi-anechoic chambers, full-anechoic chambers, and acoustics A full range of solutions including equipment, measurement methods and acoustic testing.
Relying on acoustic expertise and years of experience in acoustic laboratory construction, we have developed and produced a series of mature anechoic rooms, silent rooms and other products, which are well received by enterprises for their good acoustic effects, modular installation, lightweight and repeatable disassembly and assembly. The quality department and the R&D department are favored to provide enterprises with a complete set of software and hardware products such as acoustic testing environment and equipment suitable for noise quality testing, product research and development institutes, etc.
Design standards:
The structure of the anechoic room is based on the international standard ISO3745 "Acoustics-Determination- of sound power levels of noise sourcePrecision--- methods for anechoic and semi-anechoic- rooms" and the standard GB6882 "Acoustics: Determination of sound power of noise sources: anechoic room and Semi-anechoic chamber precision method" design. At the same time, it meets the requirements of GB/T8059 "Household and Similar Refrigeration Appliances" for the noise test standards of refrigerators and freezers.
Semi-anechoic room:
• It is used to test the sound pressure level and sound power level of household and similar electrical appliances, automobiles and parts, etc.
The analysis and research of dynamic characteristics can adjust and control the working environment conditions of the anechoic room according to the needs of the test.
• Designable background noise is less than 10 decibels; cut-off frequency is less than 50Hz
• Double-layer sound-proof building, floating damping structure;
• Isolate external noise;
• Absorb sound waves from internal sound sources without reflection;
• 360° acoustic free field environment;
• Choose imported instruments or domestic high-quality instruments and microphones;
• The software is simple and convenient to operate and easy to maintain;
