Covich spoke first, stating that ship acoustics began and matured at Carderock.
Work started in the 1940s with investigations into submarine propeller cavitation
noise. After World War II, ship radiated-noise trials began on a routine basis,
continuing through today. In 1960, NAVSEA became concerned with other kinds
of submarine noise. In 1964, the acoustics and vibrations lab was created at
Carderock. By the mid-1980s, the Ship Acoustics Department was the leader in
establishing, understanding and maturing the science of quieting ships.
