Environmental Noise Mitigation
Scope of Work
MD Acoustics is regularly engaged to provide comprehensive noise impact studies and mitigation design for high-volume express car washes located near noise-sensitive residential and commercial areas. These facilities utilize high-velocity dryer systems and extensive vacuum bays that can exceed 100 dB at the source, creating a potential nuisance for the surrounding community. Our role is to identify these acoustic liabilities during the planning phase and engineer them out of the project before construction begins.
To accomplish this, we perform on-site noise testing using calibrated Type-1 sound level meters to document existing traffic masking levels. We then develop high-fidelity 3D acoustic models using SoundPLAN software to simulate “worst-case” scenarios, assuming every dryer and vacuum station is running simultaneously. This allows us to precisely quantify sound propagation and ensure every site meets strict municipal daytime and nighttime limits.
Outcome
Through advanced modeling and strategic site analysis, MD Acoustics identifies critical noise contributors such as vacuum turbine “whine” and tunnel exit discharge. We currently solve these challenges by designing custom silencer systems and mitigation features directly into the facility’s architecture. Our standard design features include the specification of four-sided CMU turbine enclosures, high-performance acoustic tunnel liners, and restricted tunnel exit dimensions to trap noise at the source.
We further optimize site performance by strategically spacing and orienting equipment to maximize natural sound attenuation. By implementing technologies like Variable Frequency Drives (VFDs), we allow facilities to run at reduced noise levels during sensitive nighttime hours, maintaining 24/7 compliance without operational downtime. Our data-driven approach consistently results in 100% compliance with local noise ordinances, protecting our clients’ investments and ensuring their projects are welcomed by the neighborhood.
