Biography

Professor Dahl's research is in the area of acoustics, with primary focus on underwater sound. He is a member of the Acoustics Department of the Applied Physics Laboratory. His research includes:

  • Underwater acoustic remote sensing
  • Acoustic scattering and reflection from the sea surface and sea bed
  • Vector acoustics
  • Underwater ambient noise and studies on reducing underwater noise from marine pile driving

For examples of his research see: Acoustics Research in Mechanical Engineering and at the Applied Physics Laboratory.

Dahl has conducted several ocean-going experiments in underwater acoustics, including the Asian Seas International Acoustics Experiment (ASIAEX) sponsored by the U.S. Office of Naval Research and conducted in the East China Sea involving the U.S., China and Korea. Prof. Dahl was the U.S. chief scientist for ASIAEX.

Professor Dahl is a Fellow of the Acoustical Society of America (ASA), has served as the chair of the ASA technical committee on Underwater Acoustics (2002-2005), on its Executive Council (2008-2011), and in 2012 was elected ASA Vice President.
