Dr. John Kennedy

Assistant Professor (Mechanical, Manuf & Biomedical Eng)

Dr. John Kennedy is Assistant Professor in Vibrations, Acoustics and Dynamics at Trinity College Dublin. His research career focuses aero-acoustic problems and the development of novel noise control technologies. His research has applied advanced correlation and spectral analysis techniques to experimental data of turbulence (LDV, X-hotwire and high speed PIV) and included advanced beamforming and partial coherence techniques for source localisation using microphone array data. He current research focuses on the how the latest additive manufacturing technologies can be used to produce novel metamaterials for the control of enviornmental noise, including optimised design strategies using deep learning. He leads a research group of 3 PhD students and 2 Postdoctoral researchers and is co-lead in the Fluids, Vibrations and Acoustics research group. He has also engaged in interdisciplinary research with psychologists from the University of Bath and the University of Aberystwyth into the influence of noise exposure on human performance in transport applications including hazard detection, risk perception and annoyance. He has secured over EUR 2 million in research funding, including over EUR 1 million focusing on the design and additive manufacture of metamaterials. He works closely with Irish SME partners in the commercialisation of acoustic metamaterials including in the H2020 SME instrument project TANDEM. He has been the scientific coordinator and lead technical manager of the FP7 Clean Sky projects WENEMOR, ALLEGRA and ARTIC and PI on the H2020 project AERIALIST. His responsibilities on these projects included the conduct of Preliminary and Critical Design Reviews, test planning and supervision of the wind tunnel test campaigns. Dr. Kennedy has published 74 peer-reviewed journal articles and conference publications. He has been a member of the scientific committee of the 21st and 23rd Workshops of the Aeroacoustics Specialists Committee of the Council of European Aerospace Societies. He was a member of the Scientific Committee of the 45th and 51st International JVE (Journal of Vibroengineering) Conferences. He is a session chair at the Internoise 2022 and ISMA 2022 conference. He is also Irish coordinator for the industrially focused institute of Acoustics' Diploma in acoustics and noise control. His work in transport aero-acoustics has led to press releases by the Acoustical Society of America and the American Institute of Physics.
