房中房全消声室产品介绍
PRODUCT INTRODUCTION
全消声室应能提供频率范围从63Hz~8000Hz的近似自由场环境，所用的吸声材料要求吸声系数大于0.99，确保消声室从设计到完成都遵循一系列国际通用的技术规范和行业标准。可根据客户不同的本底噪声，设计相应的隔振系统、消声系统及照明电路系统等，保证满足自由场的要求，并确保本底噪声的测试数值，为测试人员提供明亮、健康和安全的工作环境。
全消自由场精度≤630Hz，偏差±2.5 dB
全消自由场精度800～5000Hz，偏差±2.0 dB
全消自由场精度≥6300Hz，偏差±3.0 dB
Frequency ranging from 63Hz~8000Hz, approximate free sound field environment. Sound absorption coefficient of the sound-absorbing material adopted is greater than 0.99. Follow the international acoustic industry standards from design to implementation. Appropriate isolation system, muffler systems and lighting circuits system can be customized according to different background noise. Guarantee to meet the free sound field requirements and ensure the background noise test values. Provides tester a bright, healthy and safe working environment.

房中房半消声室产品特性
PRODUCT FEATURES
- 半消声室除要求地面为硬质刚性反射面外，其余与全消声室相同
- 由于地面是硬的，能承受较大的重量，适宜测量如车辆、大型机器、工业设备等的噪声功率
- 完全保证噪声与振动测试的声学性能，质量可靠，截止频率低
- 出色的防火和耐冲击性能
- 金属护面板尖劈坚固耐用，使用寿命更长
- 营造绿色环保、整洁清新的测试空间
- 使用方便，造价比全消声室低
- Similar as the anechoic chamber, but the floor of semi-anechoic chamber is required to made of hard rigid reflecting surface
- Since the ground is hard enough to withstand greater weight, semi-anechoic chamber is suitable for the noise power measurements for vehicles, heavy machinery, industrial equipment, etc.
- Fully guarantee the acoustic and vibration test performance, reliable quality, low cut-off frequency
- Excellent fire protection properties with a high degree of impact resistance
- Durable metal acoustic wedge can assure years of trouble-free service
- Create a green, clean and fresh test environment
- Convenient in use, costs less than full-anechoic chamber
