We are experts in the field of traffic noise studies
Our work has included traffic noise modeling and mapping for very large projects, very small projects and everything in between.
Our noise modeling process allows us to take into account vehicle types and quantities, traffic speed, vehicle direction, road gradient and road surface type to accurately predict traffic noise levels to FHWA standards. We can assess the performance of sound barriers or other noise control methods. Traffic noise levels are typically calculated in terms of day-night average sound levels (Ldn) or peak hour average sound levels, although we can calculate noise levels using any industry standard method.
Some of our larger projects have required mapping traffic noise levels over entire Cities for General Plan updates. Smaller projects have involved noise level prediction of individual roads and intersections to assess the effectiveness of acoustical barriers or to predict noise impact at sensitive locations. Additionally, we provide a peer review service to assess traffic noise reports produced by others.
