Explore Our Services

Apex Acoustics LLC is a Maryland based consultancy firm offering technical assessment for different types of projects from major industrial and infrastructural developments to local community initiatives. We support projects at all stages, including initial planning and design, as well as facility modifications and expansions. Our project experience includes:

Environmental Noise & Vibration Studies

Our consultants have produced over 100 technical reports on environmental noise and vibration for NEPA, FERC, USACE, NOAA, HUD, CEQA, and international agencies like the IFC/World Bank. We use advanced, compliant methods and equipment. All studies are thoroughly documented to support design decisions or legal and regulatory reviews.

Environmental Noise and Vibration Measurements

Apex Acoustics provides environmental noise and vibration measurements for all project phases, including permitting, construction, operation, and decommissioning. We use NIST-traceable, calibrated instruments for accurate data collection. Results are analyzed and compared against relevant regulatory standards.

Noise and Vibration Prediction and Mapping

Apex Acoustics uses advanced 3D modeling tools like CadnaA, FHWA Traffic Noise Model, and FTA guidelines to predict noise and vibration levels during project design. We provide results in tables and contour maps, benchmarked against regulations. Modeling also helps evaluate mitigation strategies early, saving time and cost.

Noise Complaints Investigations and Mitigation Strategies

Apex Acoustics investigates noise complaints by identifying sources and assessing mitigation strategies using a combination of field sound measurements and 3D acoustic modeling. We collaborate with facility teams to optimize solutions and offer design guidance to prevent issues before construction. Proactive planning helps avoid costly post-construction fixes.

Occupational Noise Assessment

Apex Acoustics performs occupational noise assessments, including area monitoring and personal dosimetry, in line with OSHA standards. We develop cost-effective mitigation strategies and identify noise sources. Solutions include engineering or administrative control to protect worker health.

Underwater Acoustics

Apex Acoustics conducts underwater acoustic assessments to evaluate the impact of marine noise from activities like exploration and offshore construction. Using NOAA Fisheries' methods, we calculate sound propagation and impact zones on marine life. Our expertise covers both impulsive and non-impulsive sources across the Americas.

Vibration Assessment

Apex Acoustics assesses ground-borne vibration (GBV) and ground-borne noise (GBN) impacts from nearby transit and freight projects. We analyze how vibration travels into buildings, causing perceptible effects or audible noise. Our team provides conceptual engineering controls to mitigate these impacts.

Building-Envelop Noise Control

For buildings exposed to significant environmental noise from highways, railways, aircraft, industrial facilities, or other external sources, Apex Acoustics evaluates building-envelop requirements necessary to achieve interior sound levels. Our building-envelop studies can support residential, commercial, institutional, and mixed-use developments, including projects subject to HUD or local noise requirements.

Glare Analysis

Apex Acoustics perform glint and glare assessments for solar projects using GlareGuage software toevaluate impacts on airports, roads, and nearby dwellings. We analyze intensity and duration of reflected sunlight at key observation points. Results guide mitigation strategies to support project approvals and reduce opposition.

Technical Reviews

Engineers at Apex Acoustics participate in municipal peer review programs reviewing noise and vibration work conducted by other consultants on behalf of municipalities or regulators assisting them in the permitting process.

Expert Witness

Apex Acoustics provides expert witness testimony on noise and vibration issues for courts and planning boards. Our senior consultants deliver defensible reports using rigorous methods and standards. These reports support legal cases and regulatory compliance for facility design and operations.
