Title: Acoustic Chamber Characterization.

Abstract

The basis of this project was to characterize the various uncertainty contributors of an acoustic chamber. The acoustic chamber will be used to calibrate and characterize infrasound sensors used in the field in the frequency range of 0.001 Hz to 4 Hz. The components characterized include the internal volume of the chamber, the piston area of the speaker creating the dynamic sound wave, the environmental stabilization of the chamber and the chamber's leak rate. Also, the resonant frequency of the chamber was evaluated and found to be far outside the frequency band of interest. ACKNOWLEDGEMENTS The authors would like to acknowledge Randy Rembold and John Merchant for supporting and funding this project through the Defense Threat Reduction Agency (DTRA). We would also like to thank Henry Lorenzo and Monico Lucero of Manufacturing Liaison working along with Robert Jones and Tony Bryce of Mechanical Calibration for performing the dimensional measurements of the Acoustic Chamber. We would like to thank Curt Mowry and Adam Pimentel of Organization 01852 for measuring the density of a sample of the fiber-reinforced material of the grate.
