Underwater radiated noise measurements for seven types of modern commercial ships during normal operating conditions are presented. Calibrated acoustic data (<1000 Hz) from an autonomous seafloor-mounted acoustic recorder were combined with ship passage information from the Automatic Identification System. This approach allowed for detailed measurements (i.e., source level, sound exposure level, and transmission range) on ships of opportunity. A key result was different acoustic levels and…

Deep-water measurements of container ship radiated noise signatures and directionality.

Underwater radiated noise from merchant ships was measured opportunistically from multiple spatial aspects to estimate signature source levels and directionality and previously reported broadband levels at 10° aspect may be ∼12 dB lower than respective surface-affected ANSI/ISO standard derived levels.

Underwater radiated noise from commercial ships in the Yellow Sea of China

During the past decades, ship-building and engine-manufacturing have developed very quickly. The source levels of modern ships may have changed. The underwater radiated noise from many commercial

Relationship between container ship underwater noise levels and ship design, operational and oceanographic conditions

Low-frequency ocean ambient noise is dominated by noise from commercial ships, yet understanding how individual ships contribute deserves further investigation. This study develops and evaluates

Experimental Assessment of Underwater Acoustic Source Levels of Different Ship Types

The contribution of shipping noise to the background noise in the seas can be estimated by shipping noise maps. Noise maps can be made by applying appropriate modeling tools for underwater sound

Variability of underwater radiated ship noise measured using two hydrophone arrays

The impacts of man-made underwater noise on the marine environment have received increased attention over recent years, primarily resulting from recognition of the increased pressures placed on the

Shipping noise field calibration via source inversion

There is significant evidence that the low-frequency mean acoustic noise pressure level in the ocean has been constantly increasing in the last decades. The main noise sources responsible for this

Extracting Acoustic Source Information of Shipping Noise for Dynamic Ambient Noise Modelling

Shipping traffic is one of the largest contributors to anthropogenic noise in the ocean. Noise generated by merchant ships elevates natural occurring ambient noise level by 20-30 dB in many areas of

Prediction of shipping noise in the Eastern Mediterranean Sea

Shipping noise is one of the most common underwater sounds and a substantial component of ambient noise in the sea. Traveling vessels are sources of low-frequency acoustic waves which propagate



Directionality and maneuvering effects on a surface ship underwater acoustic signature.

This work examines underwater source spectra of a small (560 tons, 40 m length), single-screw oceanographic vessel, focusing on directionality and effects of maneuvers, and proposes an empirical model assuming that spectral source levels exhibit simultaneous variations in aspect angle, speed, and turn rate.

Radiated noise characteristics of a modern cargo ship

Radiated noise directionality measurements indicate that the radiation is generally dipole in form at lower frequencies, as expected, but there are some departures from this pattern that may indicate hull interactions.


The Channel Islands National Marine Sanctuary (CINMS) and the surrounding waters are considered an urban coastal environment, yet home to a diversity of marine organisms. Understanding the

An ensemble source spectra model for merchant ship-radiated noise.

An evaluation of the classical model for determining an ensemble of the broadband source spectra of the sound generated by individual ships and an alternate model to overcome the deficiencies is presented and a joint probability density on the two parameters of the single term model based on the measured histograms of these parameters is proposed.

Anthropogenic and natural sources of ambient noise in the ocean

Ocean ambient noise results from both anthropogenic and natural sources. Different noise sources are dominant in each of 3 frequency bands: low (10 to 500 Hz), medium (500 Hz to 25 kHz) and high (>25

Characterizing the Relative Contributions of Large Vessels to Total Ocean Noise Fields: A Case Study Using the Gerry E. Studds Stellwagen Bank National Marine Sanctuary

Noise produced by large commercial vessels was at levels and within frequencies that warrant concern among managers regarding the ability of endangered whales to maintain acoustic contact within greater sanctuary waters.

Deep sound channel noise from high‐latitude winds

The contribution to underwater ambient noise from the persistent winds which blow at high latitude is discussed and estimated. Energy is ducted into low‐loss paths in the deep sound channel by

Repeated ocean ambient noise measurements at a shallow water (110 m) site near San Clemente Island reveal little increase in noise levels in the absence of local ships. Navy reports document ambient
