Cities and transport
Controlling noise to enhance urban quality of life.
In urban environments and transport infrastructures, noise is a strategic issue in terms of public health, regulatory compliance and project acceptability. SIM Engineering supports local authorities, developers and operators with targeted acoustic studies, integrating measurements, modelling and technical recommendations, in order to design and operate territories that are more controlled, sustainable and acoustically efficient.

Acoustic engineering for cities and transportation
In urban environments and transport infrastructures, noise and vibration are major issues for development, public health and project acceptability. They have a direct impact on people’s quality of life, the regulatory compliance of infrastructures and the feasibility of development projects. SIM Engineering assists public and private players to meet these challenges through rigorous acoustic studies, integrated with territorial, regulatory and operational constraints.
Urban and transport noise, a population exposure issue
Cities and transport infrastructures concentrate numerous and continuous sources of noise: road and rail traffic, public transport, logistics platforms and related activities. These sources expose local populations to noise levels that are potentially harmful to their health and well-being.
According to the most recent data on environmental noise, more than 20% of the European population live in areas where transport noise levels are considered harmful to healthwhen applying the thresholds established by the European Environmental Noise Directive (END).
This prolonged exposure can be associated with physio-psychological impacts such as sleep disruption, significant discomfort, increased stress and increased risk of cardiovascular or metabolic disorders.
Acoustic engineering tailored to territories and infrastructures
SIM Engineering acts as an acoustic consultancy specializing in urban and transport acousticsOur approach is based on a detailed analysis of sources, propagation modes and interactions between infrastructures, buildings and the environment. Studies are carried out at both project and territorial levels, to provide a global and objective vision of acoustic impacts.
The areas of expertise mobilized in the cities and transport sector cover in particular:
Acoustic engineering
Our acousticians carry out impact studies and acoustic assessments to evaluate noise emissions and design solutions to ensure compliance with acoustic standards, improve sound quality or reduce noise.

Acoustic studies focused on project reliability and acceptability
The acoustic studies carried out by SIM Engineering in the field of cities and transport are designed to help decision-making and secure projects. Acoustic measurements, modeling and mapping enable us to objectively quantify noise levels, identify sensitive areas and evaluate different development scenarios.
Taking noise and vibration into account from the outset contributes directly to :
- control population exposure,
- improve project acceptability,
- limit disputes and objections,
- make planning decisions more reliable.
- control population exposure,
Integrating regulatory requirements without hindering urban projects
Urban and transport projects are subject to a demanding acoustic regulatory framework, particularly in terms of environmental noise and population exposure. Insufficient anticipation of these constraints can slow down procedures, complicate public consultations and generate additional costs.
SIM Engineering carries out regulatory acoustic studies to meet current requirements while preserving the coherence of projects and development objectives. A controlled acoustic approach facilitates exchanges with authorities, local communities and residents.
