Within the European Defense Agency (EDA), the Protection of Marine Mammals (PoMM) project, a comprehensive common marine mammal database essential for risk mitigation tools, was established. The database, built on an extensive dataset collection with the focus on areas of operational interest for European navies, consists of annual and seasonal...

The prediction of underwater noise emissions from impact pile driving during near-shore and offshore construction activities and its potential effect on the marine environment has been a major field of research for several years. A number of different modeling approaches have been suggested recently to predict the radiated sound pressure at...

Concern exists about the potential effects of pile-driving sounds on fish, but evidence is limited, especially for fish larvae. A device was developed to expose larvae to accurately reproduced pile-driving sounds. Controlled exposure experiments were carried out to examine the lethal effects in common sole larvae. No significant effects were...

The prospects for an increased future use of autonomous underwater vehicles (AUVs) in the Maritime & Offshore sector are high, mainly due to the search for cost effectiveness. AUVs reduce the need for large crews, divers and vessels in the operational area. AUVs are already operational for bathymetric and environmental mapping, pipeline tracking...

The European Marine Strategy Framework Directive requires European member states to develop strategies for their marine waters leading to programs of measures that achieve or maintain good environmental status (GES) in all European seas by 2020. An essential step toward reaching GES is the establishment of monitoring programs, enabling the state...

In recent years atypical stranding of marine life have created a public interest in military sonar use. In order to maintain this essential military capability, there is a need to ensure that active sonar systems are used in an environmentally responsible way when preparing for operational missions. Although there is NATO environmental...

A key issue when investigating effects of anthropogenic noise on cetacean behavior is to identify the biological significance of the responses. Predator presence can be considered a natural high-level disturbance stimulus to which prey animals have evolved adaptive response strategies to reduce their risk of predation by altering behavior away...

Abstract—In the framework of a bilateral Netherlands- Norway defense research cooperation (2014-2017) between The Netherlands Defence Materiel Organisation (DMO NL) and Forsvarets forskningsinstitutt (FFI NO), it has been shown that a compact general-purpose processor board developed for smartphones can be successfully used for real-time...

A set of equations to describe the performance of sonar systems, collectively known as the “sonar equations”, was developed during and after the Second World War. These equations assumed that both the sonar equipment and the object to be detected (usually a submarine) would be submerged in one of Earth’s seas or oceans, and the efficacy of the...

Impact pile driving is a method used to install piles for marine and inland water construction projects using high-energy impact hammers. The installation of hollow steel piles in this manner can produce extremely high sound levels in the surrounding waters (as well as in the air). Given the large-scale development of off€shore wind in European...

New railway vehicles in Europe have to comply with noise limits as defined in the Technical Specification for Interoperability (TSI). The pass-by test has to be carried out at a site that fulfills the TSI requirements. The need has arisen to be able to perform TSI pass-by type testing at non-compliant sites. In the ACOUTRAIN project, procedures...

The behaviour of a marine mammal near a noise source can modulate the sound exposure it receives.We demonstrate that two long-finned pilot whales both surfaced in synchrony with consecutive arrivals of multiple sonar pulses. We then assess the effect of surfacing and other behavioural response strategies on the received cumulative sound exposure...

Geleuidhinder is na luchtverontreiniging het grootste milieuprobleem voor de volksgezonheid. De meeste hinder wordt veroorzaakt door het wegverkeer. Maar liefst 3 miljoen mensen in Nederland zijn gehinderd of slaap gestoord. Ernstig gehinderd of slaapgestoord zijn bijna 1,5 miljoen mensen. Verlaging van de bron-niveaus van de voertuigen en...

Acoustic mitigation devices (AMDs) are used to deter marine mammals from construction sites to prevent hearing injury by offshore pile-driving noise. In order to quantify the distance at which AMDs designed as ‘seal scarers’ are detected by seals, the 50% hearing thresholds for playbacks of their sounds were determined. The broadband hearing...

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. The SONIC project delivers the required technical knowledge for noise mapping, based on a...

A proper spatial sampling is critical for high quality imaging. If the sampling criterion is not met, artifacts appear in the image, generally referred to as grating lobes. For inspection efficiency the width of the field of view is becoming larger leading to an increase in the number of elements and therefore transducer complexity and cost. The...
