ECOTONE™ NVH test chambers are constructed with a capability of noise attenuation from outer structures of modular panels and have all interior surfaces lined with PU wedges Foam or Metallic Wedge and Plain absorbing surfaces. This has working floors constructed with grating floor sections to support heavy test specimens above the floor wedges. This is basically designed to suppress the internal sound reflections which are used for acoustical measurements.

The effectiveness of an NVH test chamber is measured in dB of rejection, which is the ratio of direct sound to reflected sound inside the room. Our designed NVH chamber provides up to 15 dB and 100 Cutoff Hz.[/vc_column_text][vc_media_grid element_width=”2″ grid_id=”vc_gid:1468825639732-3ed51b6c-b8f5-3″ include=”1523,1525,1526,1527,2688,2689″][/vc_column][/vc_row]
