Anechoic Chambers

Anechoic chambers are acoustical enclosures where the walls, floor, and ceiling provide up to 100% absorption of the incident sound energy, making them echo free. These acoustic chambers are constructed with a noise control outer shell from our modular panels or masonry walls and have the interior surfaces lined with anechoic wedges.

• Anechoic glass-fiber wedges within required low frequency cut-offs
• Double or single wall and ceiling construction
• IAC Tranquil-Aire® Ventilation Systems – coupled to building supply
• Lighting, interior – minimally acoustically reflective
• Tubular cable ports
• Interior non-reflective cable floor above floor wedges for fully Anechoic Rooms. Nylon catch net below cable floor
• IAC Acousti-Flote Floor System with 6 1/2 Hz, rubber-in-shear vibration isolators for fully anechoic room

The shielded chamber or faraday cage included a wide range of integrated, supply and communication interfaces. Our shielding boxes with other dimensions and interfaces can be designed against the customer's individual requirements. Furthermore, RF-absorber mats, ferrite absorbers, infrared windows, ventilation (fans), lockings (for the padlock), etc will be integrated into our RF shielded boxes on request. Whatever you need it, we can build it. This shielding chamber offers the below features:

• Pneumatic soundproof box
• Pneumatic control of open-close and optional test fixture motions
• Suitable for audio testing
• DB9(RS232) Remote Control
• Stainless Steel Pneumatic air cylinder
