... with the propagation of an acoustic wave. The NoiseSpotter was deployed in an energetic tidal channel with a tidal oscillation that can approach 3 m. Performance characteristics in the presence of the resulting flow noise is quantified, and a flow noise suppression system is quantitatively shown to significantly...

... monitoring system to characterize sources of sound. Data are presented from controlled acoustic transmissions in a quiet environment and an energetic tidal channel in the presence of non-acoustic flow noise. NoiseSpotter performance is demonstrated through its modular design, ease of deployment/recovery...

... are con- sidered to be mechanically induced vibrations and are discussed in a ~ollowing section.] At present towing speeds, ~low noise is not the dominant component o~ tow noise. As speeds increase, however, flow noise will become more signi~icant due to its dependence on higher powers of velocity. Thus...
