Control of an acoustical speaker system in a reverberant chamber
Journal of the IEST
Acoustic testing using commercial sound system components is becoming more popular as a cost effective way of generating the required environment both in and out of a reverberant chamber. This paper will present the development of such a sound system that uses a state-of-the-art random vibration controller to perform closed-loop control in the reverberant chamber at Sandia National Laboratories. Test data will be presented that demonstrates narrow-band controlability, performance and some limitations of commercial sound generation equipment in a reverberant chamber.
