Experimental Assessment of Underwater Radiated Sound of Different Ship Types
, 2015 The aim of the SONIC project is to develop tools to investigate and mitigate the effects of underwater noise generated by shipping. One way to study the contribution of shipping noise to the background noise in the seas is to produce shipping noise maps.

Jet noise source distribution for coplanar nozzles: experiments and predictions [PDF]
In this paper we study the mechanism of jet noise production in coaxial flows. We shall present various experimental results for isothermal and heated coplanar jet flows of four area ratios (0.81, 2, 3, and 4), operating at different velocity ratios ...

Measurement of underwater radiated noise from a ship using self-recording hydrophones
, 2015 Inhabited environment of marine animals such as whales is gradually worse by increase of ocean noise. The greatest cause of the increase of ocean noise has been reported to be ships.

MTSA-Net: a multiscale time self-attention network for ship radiated self-noise reduction
International audienceThis study reformulates the issue of reducing ship radiated self-noise as a signal separation task involving two types of signals: the desired signal from a cooperative source and the self-noise from the towed ship.

Physics-based aeroacoustic modelling of bluff-bodies
, 2009 In this work physics-based modelling of bluff-body noise was performed with application to landing gear noise production. The landing gear is a primary contributor to airframe noise during approach.
