Transportation & Infrastructure
Quieter Roads, Railways & Transit for Stronger Communities.
From highways and rail to bridges and transit hubs, Memtech delivers data-driven acoustic and vibration solutions that protect communities, improve safety, and ensure compliance with state and federal standards.
Building Infrastructure Without the Complaints.
Transportation infrastructure keeps communities moving, but it also generates some of the most complex noise and vibration challenges.
Highway traffic, rail systems, transit hubs, and airports all produce persistent broadband noise, low-frequency vibration, and tonal peaks that impact nearby residents, businesses, and sensitive facilities.
At Memtech, we understand the regulatory scrutiny and public visibility of infrastructure projects. Our solutions are engineered, code-compliant, and defensible from predictive modeling of noise barriers for FHWA submissions to vibration isolation strategies for rail corridors. We deliver turnkey systems that protect communities, ensure compliance, and build public trust.

- Vibration undermines sensitive hardware, threatening drive stability, error rates, and long-term reliability.
- Cooling and generator noise carries into surrounding neighborhoods, triggering community complaints and regulatory scrutiny.
- Sustained equipment noise strains your staff, impacting focus, productivity, and hearing safety.
We understand what’s at stake: downtime isn’t an option, compliance isn’t negotiable, and trust with your community matters.
Common Challenges We Help Solve.
Highway traffic noise exceeding FHWA abatement thresholds.
Rail-induced vibration impacting nearby residential or historic structures.
Aircraft and ground support noise affecting surrounding neighborhoods.
Excessive reverberation in transit stations, reducing communication clarity.
Community complaints and permitting challenges tied to environmental noise impact.
Structural fatigue in bridges or retaining walls caused by vibration loading.

Where Transportation & Acoustics Work in Harmony
- Community Protection
Excessive transportation noise degrades quality of life, triggers complaints, and can delay or halt projects if left unaddressed. - Regulatory Compliance
Agencies such as FHWA, FTA, and FAA set strict criteria for noise and vibration levels. Projects must include mitigation to receive approval and funding. - Public Health
Long-term exposure to traffic and transit noise contributes to hearing loss, cardiovascular risk, stress, and reduced sleep quality in surrounding populations. - Structural Integrity
Vibration from rail and heavy truck traffic can damage nearby buildings, bridges, and historic structures if not properly controlled. - Project Viability
Proactive mitigation avoids costly redesigns, lawsuits, and project delays caused by unresolved environmental impact assessments.

Our Approach & Capabilities
Memtech provides a full suite of acoustic and vibration mitigation capabilities for transportation infrastructure. We design and deliver highway and rail noise barrier walls that meet FHWA Noise Abatement Criteria, acoustic enclosures and absorptive walls for transit hubs and maintenance yards, and rail vibration isolation systems such as resilient track fasteners and floating slab assemblies.
Our team performs on-site monitoring, frequency-targeted analysis, and predictive modeling to ensure effectiveness before construction. Solutions are built with fire-rated, weather-resistant, and crash-tested materials for 20–40+ year service life.
With design/build project delivery and validation testing, we provide complete systems that withstand heavy-duty operational demands and regulatory scrutiny.

Our approach:
- Measured & Modeled
We start with Class 1 acoustic and vibration logging, broadband and octave-band analysis to accurately map the root cause. - Frequency Analysis & Modeling
Octave-band and narrow-band diagnostics paired with 3D propagation modeling predict barrier effectiveness and vibration spread before construction. - Tailored Engineering
Solutions include noise barrier walls, acoustic enclosures, rail track isolation systems, floating slabs, and damping treatments engineered for performance and durability. - Design/Build Integration
Our team manages specification, material sourcing, and installation, coordinating with contractors and DOT stakeholders. - Validation & Documentation
Every project concludes with compliance-ready reports suitable for regulatory agencies, environmental review boards, and public hearings.

Frequently Asked Questions (FAQs)
What types of transportation projects require noise and vibration mitigation?
Highways, rail corridors, bridges, airports, and transit hubs all generate significant environmental noise and ground-borne vibration. Projects near residential, commercial, or historic areas often require mitigation to comply with FHWA Noise Abatement Criteria (NAC), FTA Transit Noise and Vibration Impact Assessment guidelines, and local ordinances.
How do you evaluate noise and vibration for infrastructure projects?
We conduct on-site acoustic and vibration monitoring with Class 1 sound level meters and triaxial accelerometers. Data is logged over multiple days to capture peak and baseline conditions. Results are then analyzed by octave-band and narrow-band frequency diagnostics and paired with 3D propagation modeling to predict community and structural impact.
What standards do your designs follow?
Our solutions align with:
FHWA 23 CFR Part 772 – Noise Abatement Criteria
FTA guidelines for transit noise and vibration
FAA standards for aircraft and ground support noise
ASTM / ISO standards for sound transmission, absorption, and vibration
State DOT and municipal code requirements
FHWA 23 CFR Part 772 – Noise Abatement Criteria

FAA standards for aircraft and ground support noise
ASTM / ISO standards for sound transmission, absorption, and vibration
State DOT and municipal code requirements
What types of mitigation strategies are effective in transportation projects?
Typical solutions include highway and rail noise barriers, acoustic enclosures for mechanical or maintenance yards, absorptive wall treatments in stations, and vibration isolation systems such as resilient track fasteners, floating slabs, or damping retrofits for bridges and elevated structures.
How do you ensure barriers and enclosures meet both acoustic and safety requirements?
We specify materials that are fire-rated, weather-resistant, and crash-tested (MASH TL-4 where applicable) to meet DOT safety requirements. Designs are engineered for 20–40+ year lifespans, minimizing long-term maintenance and replacement costs.
How do you address community noise complaints during infrastructure projects?
We provide independent monitoring, compliance-ready reporting, and predictive modeling to show anticipated improvements. Reports are written for both technical reviewers and public hearings, supporting project transparency and community engagement.
Do you provide turnkey project delivery?
Yes. We manage the full process: measurement, engineering, material specification, installation, and validation testing. This ensures projects meet regulatory criteria and performance goals with a single accountable partner.
