Sound perforated Metallic Encapsulated Wedges

After researchers’ development, Sound can provide perforated metallic encapsulated wedges (metal wedge). According laboratory testing and built anechoic chamber measurements, Sound metal wedge performs the same acoustic behavior with traditional one.

●  Impact resistance with more than 10 years life cycle

●  Without fiber-glass leaked out and without peculiar smell

●  Cleanable surfaces

●  Bright. The color of surfaces can be painted according to your requirement.

●  Reusable for anechoic chambers’ reassembly. Interchangeable and adjustable

●  High fire resistance
