Facilities in Ontario are required to apply for Ministry of Environment Environmental Compliance Approval (ECA) permits. In order to apply for this permit, facilities require an Acoustic Assessment Report that outlines the facilities current noise emissions and if they exceed the sound level limits, recommendations to control the noise. Aercoustics uses industry standard approaches and software to model each source and facility to determine the impact. From there we develop noise controls to bring facilities into compliance. On large-scale projects this can be very challenging, as we have to identify the key sources and ensure that controls are feasible and practical. We have successfully provided assessments for Thorold Cogeneration, Karmax Heavy Stamping and Ingredion.
