Dimitri Ponirakis

Senior Noise Analyst

I am a senior noise analyst and applications programmer for the K. Lisa Yang Center for Conservation Bioacoustics. My main roles are developing tools and methods for noise analysis. I develop tools to process, analyze, model, and visualize acoustic data. Software development includes development of an Acoustic Ecology Toolbox to model the loss of communication space and masking of animal vocalizations from anthropogenic and abiotic sound sources. I am responsible for carrying out noise analysis on numerous projects from liquid natural gas terminal construction and operational activities off the East Coast, to seismic prospecting in the Arctic, to looking at the impact of cruise vessels in Glacier Bay National Park in the Pacific Northwest. Previous experience includes working for noise and vibration consulting firms, and assessing and researching the environmental impact of noise from transportation, industrial, mining, and entertainment sources.
