Precision Noise Monitoring with
Advanced Sound Level Meter Solutions

Sound Level Meters are essential tools for accurately measuring and managing noise pollution in transportation environments. These devices provide real-time acoustic data to support regulatory compliance, occupational safety, and environmental assessments. In North America, B2B sectors such as transit authorities, vehicle manufacturers, and infrastructure developers rely on precision sound measurement to evaluate noise emissions, improve design standards, and ensure safe working conditions. Engineered for both mobile and stationary use, advanced sound level meters combine rugged hardware with intelligent software and cloud-based analytics to deliver reliable performance in dynamic settings. Whether for routine monitoring or specialized testing, these systems enable users to collect, analyze, and act on critical noise data with efficiency and confidence. Envirotest Transport offers high-performance sound level monitoring solutions tailored for transportation professionals committed to reducing noise impact and meeting regulatory demands in a changing acoustic landscape.

Case Studies

NYC Subway
Noise Control Initiative

 In collaboration with New York’s MTA, Envirotest Transport deployed a network of our Sound Level Meters to monitor and reduce excessive subway noise in residential zones. By using our cloud-connected devices, real-time alerts were generated for track maintenance teams, resulting in a 25% reduction in nighttime noise complaints over six months.

California Highway
Environmental Monitoring

 Caltrans partnered with us to install Sound Level Meters along key highway expansion projects in the Bay Area. Our meters allowed project managers to continuously monitor construction noise, enabling them to implement sound barriers and adjust schedules. This improved community relations and accelerated environmental approvals.

Toronto Pearson International Airport
Noise Mapping

Envirotest Transport was selected to provide an advanced acoustic monitoring system around Toronto Pearson Airport. Our Sound Level Meters helped analyze flight path noise impacts and facilitated public reporting through an interactive noise map portal. The initiative enhanced transparency and public engagement with airport operations.
