Protect Your Business. Preserve Community Trust.
Many noise control efforts oversimplify complex facilities, treating entire plants as a single noise source or addressing issues one machine at a time. This fragmented approach often leads to reactive, high-cost measures such as perimeter noise walls or extensive enclosure systems that deliver limited performance relative to their expense.
Memtech Acoustics applies a systems engineering approach to environmental noise control. We model facilities as interconnected networks of individual noise contributors, accounting for source interactions, site geometry, and local and distant boundary conditions.
This enables accurate predictive modeling of multiple control strategies and a clear cost-to-performance (“dollars per decibel”) analysis, ensuring the most effective solution is selected, not the most aggressive one.
Our work is grounded in data-driven analysis, including comprehensive sound level measurements, community impact assessments, and advanced noise modeling. Each study is tailored to the site conditions, regulatory requirements, and project objectives, producing results that are technically defensible, legally admissible, and directly actionable—supporting engineered noise and vibration control across complex industrial and environmental environments.

Our Environmental Noise Assessment Approach
One of the major issues confronting energy-producing operations is assuring compliance with state and/or local noise ordinances. Noise criteria in some communities are quite stringent, and can be difficult to achieve.
At Memtech, we determine optimum environmental noise solutions by considering the contributions of individual elements (machines) inside and outside the plant, as well as the effects of physical location, nearby buildings and the surrounding terrain. When this information is integrated into a predictive systems-based computer model, we can determine areas of potential risk.
We utilize advanced software packages for this purpose, such as ‘Vensim’, ‘Simantics’, ‘Noise Modelling’, and our own proprietary software to provide local and distant sound level predictions. These models provide an accurate estimation of noise levels at virtually any location around the plant prior to construction of the facility. Predictions can be made based on sound pressure levels at different locations, or probabilities of annoyance for local residents in any nearby area.
This approach also allows us to simulate and validate the effectiveness of noise barriers, walls, diffusers and other solutions prior to the purchase and construction of these structures. A ‘ Monte-Carlo’ analysis can then be performed by modeling various noise control elements to derive the best solution at lowest cost.
This approach can also be used in reducing noise from existing plants prior to spending money for corrective actions via a ‘trial and error’ approach. These models will determine the effectiveness of adding noise barriers at various locations around the facility, or via the addition of noise enclosures or curtains.

Machinery & Process Equipment Noise Control
Individual pieces of machinery can generate very high noise levels in ‘stand-alone’ operation; in some cases, one or two machines can dominate the overall noise within a plant. Memtech Acoustics frequently works with equipment OEMs (ABB, Kuka, Reinhart Industries and many others) to reduce noise from machinery via the implementation of design enhancements and the targeted application of noise control materials, such as resonators.
Fix the Root Causes: Don’t "Cover Them Up"
Attacking noise mechanisms at the source has many benefits, including improved life-cycle costs and higher operating efficiency. A significant reduction in noise can often be realized by implementing design enhancements to the equipment itself.

Frequently Asked Questions (FAQs)
What types of energy and environmental noise issues does Memtech Acoustics address?
Memtech Acoustics mitigates noise from compressors, turbines, pumps, blowers, cooling towers, and other process equipment at energy and industrial facilities, as well as noise associated with solid and toxic waste management. Memtech Acoustics also solves tonal noise, low-frequency hums, and vibration that affect both employees and surrounding communities.
How does Memtech Acoustics measure and assess community noise impact?
Memtech Acoustics uses professional, certified vibro-acoustic instrumentation for all environmental noise measurements. Measurement data is validated against local ordinances, and methods include short-term and long-term community noise monitoring, property line boundary surveys, and directional measurement to isolate facility-contributed noise from external sources.
Can Memtech Acoustics help with regulatory compliance and permitting?
Yes. Memtech Acoustics provides legally compliant environmental noise assessments suitable for state environmental agencies, municipal hearings, and permitting processes under local noise ordinances. Documentation includes mapped noise contours, predictive modeling, property line boundary surveys, mitigation recommendations, and expert testimony when required to support compliance or defend against community noise complaints.
What mitigation strategies does Memtech Acoustics use for energy facilities?
Memtech Acoustics typical strategies include engineered noise barrier walls, equipment enclosures, silenced ventilation systems, duct silencers for compressed air and exhaust, vibration isolation, and sound-absorptive treatments. Solutions are designed to withstand continuous 24/7 operation, outdoor weather exposure, high heat, and mechanical vibration common to energy and industrial sites.
How quickly can Memtech Acoustics implement noise barriers or enclosures?
Most engineered noise barriers and modular acoustic enclosures are fabricated in 8 to 12 weeks, depending on materials, finishes, and site conditions. Memtech Acoustics coordinates closely with manufacturer partners and manages installation or shipping logistics to align with project schedules, permit deadlines, and compliance milestones.
How does Memtech Acoustics handle community noise complaints?
Memtech Acoustics provides independent community noise monitoring, property line boundary surveys, documentation, and expert testimony when required. Data is logged during both daytime and nighttime hours using directional measurement techniques that separate the facility's acoustic contribution from external noise sources such as traffic, nearby operations, or weather. This measurement-led approach produces defensible results for compliance hearings, neighbor mediation, and ordinance enforcement.
What makes Memtech Acoustics different from other environmental noise firms?
Memtech Acoustics is vertically integrated, with measurement, design, build, installation, and post-installation validation delivered by one team. Unlike firms that provide only monitoring or only materials, Memtech Acoustics covers the full scope: identifying the root cause of a noise issue, designing the engineered fix, and validating performance with post-install acoustic testing against the original ordinance or specification target.
Do Memtech Acoustics solutions stand up to industrial and outdoor conditions?
Yes. Memtech Acoustics selects materials that are fire-rated (ASTM E84 Class A), UV-stable, weather-resistant, and vibration-tolerant. Engineered systems are designed to endure continuous operation and outdoor exposure with service lives of 20 to 40 years or more, which is essential for power plants, landfills, substations, wastewater facilities, and 24/7 industrial sites.
What is a property line boundary noise survey?
A property line boundary noise survey measures facility-generated sound levels at the legal property boundary, which is the location that local noise ordinances typically designate as the point of compliance. Memtech Acoustics performs short-term and long-term boundary surveys using calibrated sound level meters and directional microphones to document compliance or identify exceedances for developers, industrial operators, utilities, and municipalities. Deliverables include measured sound pressure level data, octave-band analysis, weather and background noise conditions, and a compliance determination against the applicable ordinance limit.
What is the difference between a short-term and long-term environmental noise assessment?
A short-term environmental noise assessment captures representative sound levels during specific operating conditions, typically over 15 minutes to 24 hours. A long-term assessment uses continuous unattended noise monitoring over days, weeks, or seasons to capture operational variability, weather effects, and day and night patterns required by many local ordinances. Memtech Acoustics selects the assessment duration based on the applicable ordinance, the operational profile of the facility, and the regulatory or legal context.
How much does an environmental noise assessment cost?
Environmental noise assessment costs vary by scope and duration. A focused short-term property line boundary survey with a written compliance report typically ranges from $3,500 to $8,000. Long-term community noise monitoring programs with multiple measurement locations, seasonal data collection, and expert testimony can range from $15,000 to $60,000 or more. Memtech Acoustics provides fixed-fee proposals after an initial scoping call so pricing reflects the specific facility, ordinance framework, and reporting depth required.
