ECOTONE™ Provides Design Consultancy and also take Trunkey projects of Reverberation Chamber. These chambers are needed to test characterization of the acoustical properties of materials. These chambers are useful to test STL / NRC performance of acoustic material.
The reverberation chamber design shall meet the test standards (STL) of airborne sound as per IS-9901(Part III) – 1981, DIN 52210 part IV – 1984, ISO: 140 (Part III) – 1995 & test standers for (NRC) airborne sound absorption of Building Elements as per IS: 8225/ISO: 354/ASTM423C
The designed reverb chamber consists: a source room , a receiver room , adequate diffusion ( stirrer) existed in both the chambers , a receiving antenna and a transmitting antenna, there are no absorbers. In a reverb chamber the aim is to create standing waves that are used to generate the high field strengths. The volume of
The size / volume of reverberation chamber should depends upon the test object, if these are the vehicles / large machine than it size should enable DELTA to generate immunity radiation on vehicles and large machines and if these are building products than size of chamber may be smaller. Testing of lower frequencies requires a large chamber to create the standing waves, the chamber must be at least half a wavelength even for small test object..
