Features 1 A form of room-with-a-room is optional for achieving a background noise < 10 dBA 2 The inside and outside rooms can be assembled using CA panels with Rw up to 56 dB 3 Fiber-glass and metal wedges for option with lowest cutoff frequency of 50 Hz 4 Low noise ventilation with SPL <20 dBA 5 Floating floor with rubber or other-type vibration isolators 6 All elements of CA anechoic chambers are certified The most advantageous is that: CA anechoic chamber can be easily disassembled and reassembled. After reassembly, there is no impact on the acoustic performance CA perforated metallic encapsulated wedges After our researchers’ development, CA can provide perforated metallic encapsulated wedges (metal wedge). According laboratory testing and built anechoic chamber measurements, CA metal wedge performs the same acoustic behavior with traditional one. Many metal-wedge anechoic chambers have been provided by CA in recent years. It is proved that, compared to traditional one, metal wedge has features as follows: 1 Impact resistance with more than 10 years life cycle 2 Without fiber-glass leaked out and without peculiar smell 3 Cleanable surfaces 4 Bright.
