Bispectrum of ship-radiated noise [PDF]
The Journal of the Acoustical Society of America, 1989 The bispectrum of ship-radiated noise is estimated. The noise was received on a towed array being towed by the same ship that served as the noise source. The array was beamformed such that the forward endfire beam pointed toward the towing platform and the broadside beam sampled the environment without the radiated noise of the ship.

Ship noise inhibits colour change, camouflage, and anti-predator behaviour in shore crabs
Current Biology, 2020 Ship noise is a prominent source of underwater sound pollution. Carter et al. demonstrate that ship noise has multiple negative effects on animal traits that do not primarily rely on acoustics.

Vibration analysis of multi-span beam system under arbitrary boundary and coupling conditions
Zhongguo Jianchuan Yanjiu, 2017 In order to overcome the difficulties of studying the vibration analysis model of a multi-span beam system under various boundary and coupling conditions, this paper constructs a free vibration analysis model of a multi-span beam system on the basis of ...
