Don Ross (June 9, 1922 – August 24, 2015) was a civilian submariner and acoustics expert. From 1945 to 1987, Ross worked largely with the US Navy, making developments in reduction of submarine detection and underwater noise. Ross is credited with discovering that low-frequency ocean ambient noise is largely determined by shipping, and that ocean ambient noise has been steadily increasing due to human activities. He also made the first detailed measurements of the noise characteristics of nuclear submarines.
