Acoustic Design of Large Reverberant Chambers

Acoustic testing of space systems and components is essential to the assurance of launch viability. Large acoustic test chambers that permit system-level testing are rapidly becoming the norm. The initial cost of such installations is typically 5 percent of that of a single large satellite. Their cost-effectiveness is easily demonstrated. This article provides design information on calculation of noise input power requirement; sound field uniformity; acoustic fatigue of chamber; noise breakout and soil vibration; and future trends in design.
