Design And Construction

Reverberation chambers are used to create a diffuse incidence sound field, where multiple types of acoustic measurements can be performed. The chambers tend to have a large volume in order to extent the reverberation time. However, this requirement may be conditioned by the cost and the infrastructure limitations. This paper presents the design and construction of a small-scaled reverberation chamber of 3 m3 for middle-high frequency acoustic measurements. On the design, the acoustic characteristics of chamber are confirmed via finite element computer simulation. As case studies, absorption and scattering coefficients of several materials and diffusors are measured. The reverberation times needed for the measurements were obtained by the impulse response integration method. The small reverberation chamber demonstrated to be a reliable tool for middle and high frequency acoustic measurements.

Simulation Results

This paper presents the electric field characteristics in a reverberation chamber which is an electromagnetic compatibility test facility that uses a stirrer to generate a uniform electric field inside it. In this paper, a diffuser is introduced from acoustics and newly designed to overcome problems of a stirrer. To validate the effect of a diffuser, a composite quadratic residue diffuser and a reverberation chamber are modeled. Then, the field uniformity inside the reverberation chamber is simulated by XFDTD 6.2 simulation program. Simulation results show that the electric field uniformity in the reverberation chamber satisfies the international standard requirement. This shows that the composite quadratic residue diffuser can be substituted for a stirrer.
