Senior Research And Development Mechanical Engineer, Acoustics And Vibration
CurrentCollaborate with a team of design engineers by providing mechanical acoustic, vibration, and climatic environmental testing. Utilize large loudspeakers, electrodynamic shakers, and climatic chambers to recreate real-world dynamic conditions for full systems, subassemblies, and components. Work with a diverse group of engineers and technologists to ensure excellent test practices are being followed and to validate results. Collect data from calibrated precision sensors such as microphones, accelerometers, and thermocouples. Analyze the data using digital signal processing techniques to compute useful quantities, such as: auto and cross power spectral densities, transfer functions, nth octave sound pressure levels, signal correlations, shock response spectra, etc. Provide stakeholders with clear and accurate reports that describe test setup documentation, results analysis, and design recommendations.In addition to my roles in day-to-day environmental testing, I also participate in research and development groups to advance acoustic and vibration testing and analysis capabilities. I have implemented multiple input acoustic and vibration techniques for improved overall dynamic response. I maintain contracts with university researchers to develop time-reversal signal focusing techniques to increase acoustic testing efficiency. I characterize material properties using ultrasonic test methods. I implement non-contact measurement technologies such as scanning laser doppler vibrometry for vibration and ultrasonic analysis. I have measured the acoustic response of loudspeakers in an anechoic chamber and firearms at a test range.
