Christopher Allen works for NASA as Manager of the Johnson Space Centre Acoustics Office. I was fortunate to meet him the 2017 Australian Acoustical Society Conference in Perth where he was attending as one of the keynote speakers. Prior to this conference I had never thought about what role acoustics has in space but I am fascinated by space and space flight and it turns out NASA faces some pretty interesting challenges in terms of acoustics.
