As "standard laboratories" for acoustic testing, anechoic chambers and semi-anechoic chambers are widely used in electronics, automotive, aerospace, home appliance and other industries due to their precise sound wave control capability. They provide a free-field and semi-free-field quiet testing environment for product detection to ensure product testing accuracy.
The chambers adopt a double-layer independent suspended assembly structure. The exterior uses self-developed composite thin-plate resonance noise reduction technology, the interior is equipped with flat or wedge-shaped sound absorbers, and the bottom is fitted with damping shock absorbers. All materials meet fire safety and environmental protection requirements.
Based on mature acoustic design concepts and advanced material technology, this product series provides customized sound field solutions for different testing needs, helping customers achieve efficient and accurate product acoustic performance testing.

- Features:
- Multi-layer Sound Insulation Structure Design: Adopts a double-layer independent suspended assembly structure. The exterior uses independently developed composite thin-plate resonance noise reduction technology, the interior uses flat or wedge-shaped sound absorbers, and the bottom uses damping shock absorbers to effectively block external interference such as traffic noise and equipment vibration noise. The inner layer is equipped with independently developed high-efficiency sound-absorbing wedges with a sound absorption coefficient of over 0.99, which can maximize the absorption of indoor sound waves and avoid the impact of reflected sound on tests.
- Ultra-low Background Noise Level: Through structural optimization and material upgrading, the minimum background noise of this series of anechoic chambers can be as low as below -7dB(A), far exceeding industry conventional standards, and can meet the calibration and testing needs of ultra-high-sensitivity acoustic devices such as microphones and sensors.
- Customized Spatial Layout: Can be customized in size according to customers' test sample dimensions (from small electronic components to large automotive parts) and test equipment requirements. Equipment installation interfaces, ventilation and heat dissipation systems, and observation windows are reserved to balance test convenience and environmental stability.
