    Abstract

    National Aeronautical Laboratory is establishing an Acoustic Test Facility, which initially comprises of a llO0, cu.m Reverberation chamber (RC). The frequency response of the FC is determined by a Series of generate resonant modes (eigen nodes) which depend only on the dimensions of the chamber. An estimate of the eigen modes and its frequency distribution is made to evaluate the low frequency behaviour of the chamber.
