Title: Energy Based Acoustic Measurement Senors
Agency: NASA
Contract: NNS05AA38C
Award Amount: $99,996.00


This research focuses on fully developing energy density sensors that will yield a significant benefit both for measurements of interest to NASA, as well as for general acoustic measurements. Previous research has developed prototype energy density sensors. The Phase I research will focus on developing effective calibration techniques for these probes, testing and validating the probes to identify the most effective design, developing a software interface to facilitate user-friendly data acquisition, and developing software to measure acoustic directivity and sound power using the energy density sensors. An initial feasibility study will also be carried out to investigate high-temperature, high-pressure designs that are suitable for NASA needs. Phase II research objectives extend the use of these sensors to measure source directivity and sound power. Energy propagation will be determined from these measurements. A major Phase II focus will be the development of a high-temperature, high-pressure design for the energy density sensor, as well as investigating nonlinear effects on these energy-based measurements.NASA applications of the technology include characterizing radiation from rocket plumes to better understand the mechanisms involved and to match numerical codes. Non-NASA applications are many, including such tasks as in-situ measurement of sound power and radiation characteristics of sources.
