Meridian Consultants has the capability to evaluate noise sources associated with a range of projects, from special events to spectator sports facilities, land development, and vehicle traffic. All measurements are taken in accordance with accepted methodologies such as ISO or ASTM, using Type I/II integrating sound level meters. Evaluations are made in reference to community planning standards, such as local noise control ordinances and the California Model Community Noise Control Ordinance, and are based on accepted community noise equivalent level/day-night average sound level (CNEL/Ldn) measurement methodology.
Meridian Consultants utilizes computer models to predict noise impacts from increased traffic volumes or other activities associated with proposed land uses. Anticipated noise levels are projected with respect to parcel boundaries or planimetric features and in accordance with applicable regulations or client objectives. Predictive studies may address a variety of variables, such as traffic volumes, vehicle mix, stationary source operation patterns, topographic conditions, and mitigation options.
Our noise services include:
Noise level management
National, state, and/or local Register resource evaluations
Noise contour mapping
The Meridian Consultants staff has prepared Noise Control Plans as part of mitigation requirements and conducts long-term noise monitoring. We own several noise monitors and related equipment and have the staff available to mobilize and monitor noise on short notice. The Noise Control Plans incorporate the most practical and effective measures to mitigate noise and vibration impacts from the construction activities.
Our plans include the following elements:
Noise monitoring with state-of-the-art equipment
Reporting and availability of monitoring data
Mapping of sensitive receptors and noise monitoring meter locations
Action levels to evaluate noise from construction operations
Complaint resolution process
Jesse did a great job on the site collecting the noise readings. Also greatly appreciated is the rapid turnaround on the reports. I look forward to working with Meridian again in the future.

In-House Noise Specializations
Meridian Consultants has the capability to provide evaluations on various components of helicopters and helipads as it relates to noise. We utilize the Aviation Environmental Design Tool (AEDT 2d) and SoundPLAN to provide noise evaluations and abatement recommendations for various helicopters and flights paths.
Sound Wall Studies
Meridian Consultants has the capability to provide evaluations on proposed development adjacent to highways as it relates to noise. We utilize the SoundPLAN model to provide assessments and recommendations for sound walls, hardscape features, and landscaping for noise attenuation.
Meridian Consultants has the capability to provide environmental noise and vibration assessments for a wide variety of issues including: aircrafts, railroad, transportation, spectator sports facilities, live music events, and much more.
