Purpose:

1. DNV INDUSTRIAL SYSTEMS PVT. LTD. C-286,SECTOR-10,NOIDA(UP),INDIA,(M) 9811235614 ANECHOIC CHAMBER Technical Sheet Technical Sheet Technical Sheet ISO-9001 ISO-14001 Purpose: NVH/ Engine test bench are commonly used to perform test/experiments in nominally jn free field conditions. In these chambers sound energy reduces and travels away from the source with almost none being reflected back. The main and common work of these chambers is that these chambers measure the transfer function of a sound source or the directivity of noise radiation from industrial machinery. DNV Industries make use of sophisticated technology for manufacturing these chambers NVH Chambers provide a standard, reproducible environment for the measurement of a wide variety of electrical and electronic devices to establish that they meet requirements concerning spurious, harmonic and noise emissions. Scope ; 1.Engine testing. 2.Automobile testing. 3.Auto transmission testing. 4.Starter and alternator sound testing 5.Auto component sound level testing. 6.Vehicle sound testing’ Technical Specifications: Modular Design / Maintenance Friendly Shielding effectiveness -30 to 80 db(A).
