20 Years of Experience in Acoustical Consultancy Business

Apex Acoustics is a full-service consulting firm specializing in the fields of noise, vibration, shadow flicker, and glint/glare hazards. We provide these services to a variety of clients in the energy, industrial, and surface transportation sectors. Our staff have over 20 years ‘experience in engineering acoustics and understand the challenges in achieving compliance with noise, vibration, shadow flicker, and glint/glare regulations and have achieved successful results on a variety of projects.

Apex Acoustic experts are skilled at using the necessary measurement equipment and modeling software to deliver reliable and accurate results on a wide variety of complex projects within and outside the United States. We apply the latest software tools to model airborne sound levels (CadnaA, TNM) for industrial and roadway/rail transit projects, shadow flicker (windPRO) for wind energy projects, and glint/glare hazards (GlareGauge) for solar energy projects. We have experience with the Federal Transit Administration (FTA) procedures and guidelines for assessing noise and vibration impacts for rail transit projects.

We Hold Professional Licenses from Accredited Institutions

Apex Acoustics experts hold Professional Engineering licenses in Maryland and maintain active memberships with industry leading organizations.

These qualifications keep us up to date on the latest issues in the industry and enables us to apply this knowledge for our client’s projects. Our acoustic experts serve as expert witnesses on noise control issues before local siting boards and regulatory agencies.

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. Our projects include work on initial design of facilities as well as modifications. The types of projects we work on include:

Environmental Noise & Vibration Studies

Our consultants have produced over 100 technical reports on environmental noise and vibration for NEPA, FERC, 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 TNM, 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 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 controls 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.

Shadow Flicker Analysis

Apex Acoustics conducts shadow flicker assessments for wind energy projects using windPRO software to predict when and where turbine shadows may impact nearby buildings. This flickering effect, though limited annually, can influence project approval. We provide detailed shadow maps and recommend mitigation strategies to reduce impact.

Glare Analysis

Apex Acoustics performs glint and glare assessments for solar projects using GlareGauge software to evaluate 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.
