About the Noise Emission Solution

What is noise emission?

Noise emissions in the context of shipping refer to the sound generated by maritime activities, particularly from ships. This noise originates from various sources such as engine operation, propeller cavitation, machinery, and the interaction of water with the hull.

As ships traverse waterways, they emit sound waves that propagate through the marine environment. Noise emissions are a concern due to their potential adverse effects on marine life, including disruption of essential behaviors such as communication, navigation, feeding, mating, and avoidance of predators.

How do I check noise emissions?

To check noise emissions, various methods can be employed. One common approach is to utilize specialized equipment such as sound level meters or hydrophones, which measure sound levels both underwater and in the air. These devices provide quantitative data on the intensity and frequency of noise emitted by ships.

Additionally, regulatory bodies may establish guidelines and standards for measuring noise emissions, which can serve as reference points for assessment. Consulting with experts in maritime noise monitoring and adhering to applicable regulations are essential steps in effectively evaluating noise emission levels.

Thanks to our solution, you just have to enter the departure port and the destination port to have the noise emissions on the voyage.

What are different sources of noise emissions?

Various noise emissions sources influence ships’ acoustic footprint, each making its contribution. Notably, engine operation plays a significant role in generating noise through combustion and mechanical processes. In addition, considerable noise is produced by propeller cavitation, which involves the formation and collapse of water vapor bubbles around rotating propellers.

Furthermore, the noise emissions from ships are further intensified by the machinery and equipment onboard, including pumps, compressors, and ventilation systems. Additionally, the interaction between the ship’s hull and water generates hydrodynamic noise as the vessel travels through the water. A comprehensive understanding of these different sources is vital for the development of effective strategies to reduce noise emissions and mitigate their impact on marine ecosystems.

Importance of Noise Emissions Calculation

Noise emissions calculation plays a crucial role in promoting sustainable shipping practices, protecting marine ecosystems, and ensuring the well-being of both marine life and human populations.

Environmental Impact

Excessive noise emissions can disrupt marine ecosystems, affecting the behavior, communication, and survival of marine life. By calculating noise emissions, it’s possible to assess their potential impact on sensitive habitats and species.

Regulatory Compliance

Numerous nations and global establishments have implemented regulations and recommendations to restrict the emission of noise from vessels. The computation of noise emissions aids in guaranteeing adherence to these guidelines, preventing any fines, and supporting the implementation of environmentally friendly maritime strategies.

Health and Safety

Noise pollution from shipping can also have implications for human health and safety, particularly for those working on ships or residing in coastal communities. By quantifying noise emissions, measures can be taken to mitigate potential health risks and improve overall safety.

Technological Development

Calculating noise emissions provides valuable data for developing and implementing technologies aimed at reducing noise pollution from ships. This includes advancements in quieter propulsion systems, sound insulation materials, and operational practices that minimize noise generation.

Public Awareness and Engagement

Understanding the extent of noise emissions from shipping helps raise public awareness about the issue of marine noise pollution. It encourages stakeholders, including shipping companies, regulatory agencies, and the general public, to take collective action to address this environmental challenge.

Our calculator utilizes our measurement engine, which has been accredited by the Smart Freight Centre (SFC) for its compliance with the GLEC Framework.

This accreditation confirms that our technology for measuring carbon emissions meets high standards in terms of precision and reliability.

Sound Exposure Level (SEL) is a metric used to quantify the cumulative impact of sound over a specified period, typically one second, on a logarithmic scale measured in decibels (dB).

It is commonly used in assessing noise exposure in various environments, including maritime settings such as shipping.

Noise emissions from ships can disrupt the behavior, communication, and navigation of marine animals, including whales, dolphins, and fish. This disturbance can lead to stress, habitat displacement, and even physical harm, impacting marine ecosystems and biodiversity.

International regulations such as the International Maritime Organization’s (IMO) International Convention for the Prevention of Pollution from Ships (MARPOL) Annex VI include guidelines for controlling noise emissions from ships. Additionally, various countries have their own national regulations and standards addressing noise pollution in maritime environments.

Noise emissions from ships can be reduced by implementing various measures, including using quieter propulsion systems, hull design modifications, insulation materials to dampen noise, and improved operational practices such as reducing speed in sensitive areas.
