Dr. Krish Ahuja, Regents Professor at Georgia Institute of Technology (Georgia Tech) helped attendees at the eighth annual Electric Aircraft Symposium understand an unusual set of problems by starting off with an explanation of acoustics for non-acousticians. His credentials, impressive as they are, are more than matched by his ability to help those outside his specialty understand his discipline. According to his Georgia Tech web page, “Dr. Ahuja is a former associate editor of the AIAA Journal and also a former Chairman of the AIAA Aeroacoustics Technical Committee. Dr. Ahuja has authored or co-authored over 180 technical articles or reports on a range of topics including acoustic shielding, fan noise, active flow control, flow/acoustic interactions, jet noise, cavity noise, automobile noise, sonic boom research, psychoacoustics, high-temperature fiber optics strain gauges, acoustic transducers, active noise control, tilt rotor noise, source separation, acoustic fatigue, duct acoustics, computational aeroacoustics, innovative flow visualization techniques, tornado signatures, rapid charging of batteries and others.” He ran …
