Reducing noise pollution,
but why?

Noise is generally considered a disturbance, a nuisance, or an environmental pollution, but it also poses a health risk. Indeed, noise is the second most damaging environmental factor in Europe, after air pollution.

Even though the effects can vary greatly from one individual to another for the same level of noise exposure, this accumulation of high-intensity noise can lead to the development of chronic diseases and sleep disorders. Noise is ubiquitous in daily life: roads, airplanes, railways, transportation, industry, and even workspaces. It has real effects on health, well-being, and productivity.

With increasingly strict compliance requirements, noise monitoring plays a crucial role in many sectors: transportation, infrastructure, buildings, and urban construction.

Transform environmental data into actions:

Understand the impact of noise pollution to anticipate and promote healthier decisions.

Types of noise measured
  • Ld (for Level day) corresponds to the average noise level during the period from 6 AM to 6 PM
  • Le (for Level evening) corresponds to the average noise level during the period from 6 PM to 10 PM
  • Ln (for Level night) corresponds to the average noise level during the period from 10 PM to 6 AM
  • Lden (Level Day Evening Night) corresponds to the average noise level over a 24-hour period, with penalties for the evening and night

Parametric simulation

Parametric simulation allows you to adjust and test different parameters in order to model the impacts of noise pollution under various conditions. With this approach, you can simulate specific scenarios based on sound sources, geography, infrastructure and local environmental data.

Available parameters
  • Street / building level (geographical resolution)
  • Average noise level (period of a given day)
  • Road noise
  • Aircraft noise
  • Railway noise
Customized to your needs

Tailor our noise monitoring and analysis solutions to your specific needs: select the relevant indicators, define the areas to be monitored and receive customized reports for targeted, effective action.

Noise modeling is carried out using a combined emission model and a propagation model. The techniques used by Meersens are derived from a research context conducted by renowned organizations and institutions. The methodology is now recognized by the European Commission and regulated by the directive on environmental noise. To establish a noise map for an urban area, the target location is divided into a grid of emitters (noise producers) and receivers (points where the noise level will be calculated). Noise maps are then produced by taking into account all the specific characteristics of the terrain (topography, buildings, roads, etc.) and considering the sound reality of an urban area.

Strategic noise maps

Intended for cities and urban planning projects

Since 2002, France has mandated the creation of strategic noise maps to better assess and manage noise disturbances, in accordance with the European directive (2002/49/EC).

These maps are essential for protecting our sound environment and concern:

  • Roads with more than 3 million vehicles per year,
  • Railways with more than 30,000 train passages annually,
  • Major airports with more than 50,000 aircraft movements each year,
  • Urban areas of more than 100,000 inhabitants.

Construction site noise maps

Intended for stakeholders in the construction sector, integrators, and infrastructure managers

This solution offers a comprehensive approach to acoustic management of construction sites at all stages of the project.

  • Generation and simulation of the initial noise map (state 0): Before the start of the work, a predictive sound simulation is carried out to establish a clear understanding of the sound situation in the surrounding area.
  • Generation of noise maps for each construction phase: These maps are generated at each stage of the construction site, allowing for the anticipation and management of noise disturbances while complying with regulations.

Construction noise monitoring

🚧 Construction

Generation of noise maps.

Construction companies seek to limit noise disturbances generated by their activities and aim to assess and minimize the impacts of their sites on surrounding areas. By integrating a noise monitoring solution, they can obtain real-time data on noise levels in each work zone and generate accurate noise maps.

With this visualization, companies can identify and anticipate areas at risk of noise disturbance while strictly adhering to current regulations.

Noise monitoring in the workplace

💼 Companies

Enhancing productivity and well-being in the workplace.

In order to improve employee comfort in an open office, companies face a challenge: ambient noise disrupts concentration and decreases productivity.

By using strategically placed noise sensors in the workspace, the company can monitor noise levels in real-time. This data can be analyzed to identify the noisiest areas and the times of day when noise levels are highest. Based on this information, the company can reconfigure the layout of the space, install soundproofing materials, or implement noise management policies to create a quieter environment conducive to concentration.

Noise monitoring in cities

🏙️ Smart Cities

Ensuring public health and well-being.

Local authorities are constantly seeking ways to improve the quality of life for their residents, and effective management of urban noise is a crucial aspect. By using noise data, cities can identify and mitigate disruptive noise sources, thereby enhancing the quality of life in residential neighborhoods, commercial areas, and public spaces.

Noise monitoring thus becomes an essential strategic tool integrated into urban planning, demonstrating commitment and enhancing the attractiveness and reputation of the city as a place conducive to everyone’s flourishing.
