Sound - whether we want to maximize it or reduce it - is an important element of our environment. WSP offers in-depth expertise in all aspects of environmental acoustic services, from baseline noise level monitoring and the development of noise models, to monitoring programmes in support of environmental impact assessments.


State-of- the-art equipment, coupled with strategic modelling and risk assessment techniques, enable WSP to evaluate problems accurately and engineer workable solutions to complex and potentially costly environmental issues.

Our approach to environmental acoustics is characterised by depth of expertise and a commitment to quality assurance and innovation. Our modelling experts have a range of resources available from initial screening assessments to complex source and terrain modelling. These are used on a client- and project- specific basis to provide the most appropriate solutions. As needed, we can call on our experts from around the world to ensure all aspects in acoustic monitoring and modelling are covered and thereby comply with international standards and methods.

Our core environmental acoustics management services include:

  • Acoustic impact assessments
  • Baseline noise level assessments
  • Best practical available technology assessment
  • Noise source inventories
  • Noise source monitoring – point, line and area
  • Predictive acoustic modelling
  • Quantitative health risk assessments for hazardous noise levels
  • Vehicle noise monitoring


Instrumentation and Monitoring

We have installed and monitored geotechnical ground and building monitoring systems associated with shored excavations, tunnels, dams, dewatering projects, and for slope stability. Our clients include large- scale general contractors, governments, transit and transportation organizations as well as major energy companies.

  • Vibration and Ground Movement Monitoring
  • Remote and Real Time Monitoring
  • Shoring Monitoring
  • Building/Structure Deformation Monitoring (Movement, Tilt, Strain, Load, Pressure)
  • Underwater surveillance for marine infrastructure

Noise and Acoustics

Our experience includes noise exposure forecasts, noise level surveys, regulatory compliance, noise source identification and noise reduction proposals. Our team also contributes to project management with a view to implementing corrective measures to reduce noise in industrial areas.
