NOISE IMPACT ASSESSMENTS
Measured Sound.
Managed Impact.
Whether you’re planning a new facility, expanding operations, or undergoing permitting, we can help ensure that your project meets regulatory limits and minimizes disruption to nearby communities.
Why a Noise Impact Assessment Matters
As someone evaluating or managing a high-stakes project, whether a data center, campus, or transit hub, you know the EIS process is the most critical environmental safeguard.
Under NEPA (or state equivalents), your project must assess noise and vibration impacts, explore alternatives (including no-action), and propose mitigation before approval.
Our noise impact assessments provide site-specific analyses that anticipate and address community concerns, technical risks, and operational challenges before they become obstacles.

Our noise impact assessments provide site-specific analyses that anticipate and address community concerns, technical risks, and operational challenges before they become obstacles.
We can help you:
- Avoid costly delays due to noise-related objections
- Meet local, state, and federal permitting requirements
- Understand and mitigate community sound impact
- Communicate effectively with municipalities and stakeholders
Common Challenges We Solve.
Construction Noise Compliance
Managing temporary or long-term noise exposure during development.
Transportation & Logistics Operations
Truck idling, loading docks, or fleet movement exceeding allowable limits.
Industrial Machinery Retrofits
Diagnosing and correcting equipment-generated vibration or tonal issues impacting workers or communities.
Community Noise Complaints
Persistent neighbor or municipal noise concerns requiring objective data and engineered mitigation.
Permitting & Zoning Approvals
Projects stalled due to acoustic criteria or environmental noise objections.
Expansion Planning
Quantifying added noise from new equipment or facility growth before construction begins.
NOISE IMPACT ASSESSMENT
Our Approach & Capabilities
We specialize in noise impact assessments across sectors such as data infrastructure, transportation, energy, and development.
We deliver site-specific baseline studies, frequency-targeted analysis, predictive modeling, and impact forecasts to produce defensible alternatives and mitigation plans.
We deliver site-specific baseline studies, frequency-targeted analysis, predictive modeling, and impact forecasts to produce defensible alternatives and mitigation plans.
Our approach:
- Define Scope
Establish study boundaries, regulatory requirements, and sensitive receptors. - Measure Baseline
Conduct on-site noise surveys using acoustic instrumentation. - Model Impacts
Use 3D predictive modeling to simulate sound and vibration propagation under multiple scenarios. - Design Mitigation
Engineer noise barriers, enclosures, damping systems, or isolation strategies tailored to the site. - Deliver Documentation
Provide compliance-ready reports that satisfy NEPA, state, and local review boards. - Support Stakeholders
Present findings at public hearings and agency reviews with clear, defensible evidence.
What’s Included in an Acoustic EIS
Our Environmental Impact Study services are tailored to your site, local ordinances, and project scope. We combine on-site measurement, modeling, and code interpretation to deliver detailed, accurate assessments.
Baseline Ambient Sound Measurement
Field testing to capture existing background noise levels near the proposed site.
Predictive Acoustic Modeling
Computer simulations showing the projected sound impact of your facility using real-world topography, wind, and reflective surfaces.
Noise Source Identification
Analysis of contributing systems such as HVAC units, loading docks, mechanicals, and site traffic.
Compliance Benchmarking
Comparison to local sound ordinances (e.g., decibel limits at property lines during day/night hours).
Mitigation Recommendations
If issues are identified, we include solutions such as barrier walls, enclosure design, or orientation changes.
Formal Report for Submission
A complete, professional report suitable for submittal with your permitting documents, including maps, tables, and summaries for planning officials.
Who Needs an Acoustic Environmental Impact Study?
- Developers preparing zoning, rezoning, or site plan approval packages
- Municipal agencies evaluating noise in public space design
- Architects and engineers planning large-scale builds
- Businesses expanding operations near residential or sensitive zones
- Energy or industrial operators in compliance-sensitive areas

At Memtech, acoustics is what we do. Our engineers oversee every stage, ensuring that each project is properly delivered, on-time and within budget. This integrated approach delivers predictable results and protects your investment.
Certified and Licensed Professionals
Testing conducted by engineers and acoustic specialists, not general contractors or “safety consultants.”
National Standards Alignment
We follow OSHA 1910.95, NIOSH criteria, and ANSI S12.19-1996 methods for noise exposure assessment. Measurements are conducted via ISO procedures or per academically accepted methods.
Engineering Expertise
Your results are reviewed by professionals who understand both the physics and the audible consequences of the noise data.
High Responsiveness, Proven Reliability
We are your trusted local partner providing on-demand support and dependable project execution. Michigan-based with regional reach and national* shipping capabilities.
Confidential & Detailed Reporting
We don’t just submit a report. You get full documentation, delivered in easy-to-understand language with visuals and defensible insights you can act on.
*Shipping available across the continental USA; installations are offered in select regions.
Frequently Asked Questions (FAQs)
What is an Environmental Impact Study (EIS)?
An EIS is a detailed, interdisciplinary report under NEPA that identifies a project’s potential environmental impacts, including noise and vibration, and evaluates alternatives, including a no-action scenario.
What is a Noise Impact Assessment?
A Noise Impact Assessment is a technical evaluation that quantifies how existing and proposed activities will affect the surrounding acoustic environment. It is a critical part of planning, environmental permitting, and design for industrial, commercial, energy, and infrastructure projects.
What’s the difference between a Noise Impact Assessment and an Environmental Impact Study (EIS)?
An EIS covers all environmental factors—air, water, ecology, traffic, etc.—while the NIA focuses exclusively on the acoustic and vibration portion. Memtech provides the specialized noise and vibration section often used within larger EIS submissions.
What goes into the noise analysis section of an EIS?
Baseline ambient conditions
Impact modeling for each alternative
Human and wildlife exposure analysis
Mitigation strategies, costs, and implementation plans

Human and wildlife exposure analysis
Mitigation strategies, costs, and implementation plans
When is a Noise Impact Assessment required?
Typically during site development, permitting, or major equipment additions where regulations or community guidelines set maximum noise limits. Many local ordinances or environmental agencies require an NIA as part of project approval.
How do you address cumulative noise impacts?
We layer modeling of adjacent developments and long-term use to account for additive or synergistic noise effects.
Can Memtech recommend or install mitigation solutions?
Yes. We provide engineered recommendations and can coordinate procurement and installation of verified noise control systems for a turnkey solution.
