Industrial Noise & Vibration Solutions: Expert Acoustic Consultation
Noise and vibration consultant
SECTORS
Cerjan Acoustics, noise and vibration consultants, tackle your toughest noise challenges across various industries. We offer expert noise measurements and analysis for Bitcoin mining operations, power generation, traditional mining, solar and wind farms, and general industrial facilities. From regulatory compliance to optimizing noise control strategies, Cerjan Acoustics helps you achieve your business goals in a sound environment.
SERVICES
Noise Measurements are a key part of what we do and require high-quality equipment, experience, and attention to detail to ensure our clients get data they can rely on. Our measurements include short and long-term monitoring, defining source levels, assessing compliance, defining background levels, and more. We are familiar with the applicable American Society for Testing and Materials (ASTM), The American National Standards Institute (ANSI), and the International Organization for Standardizations (ISO) specifications.
Noise Modeling requires in-depth knowledge and experience in order to generate reliable results. Our detailed modeling efforts use the SoundPLAN software package as our primary tool, which implements a variety of international standards, including the General Prediction Method and ISO 9613-2. Our clients appreciate our GIS capabilities to help gather input data and distribute our results.
Noise Compliance and Mitigation involves interpretation of the applicable noise standards which is a critical piece when providing an assessment. Our firm has experience doing this all over the world and have found our clients to appreciate clearly defining the goals up front prior to investing in any necessary noise mitigations.
Assessments, Documentation, and Testimony providing a professional assessment of a project is not taken lightly as our reputation and future are on the line. Our education, experience, and background provides the fundamentals necessary for provide a defensible assessment. We follow this up with in-person testimony where we are able to directly support our clients projects.
ABOUT
Cerjan Acoustics was started by Jeff Cerjan in 2017, but he has been a consultant for the past 26+ years. Jeff got his Bachelor of Science in Aerospace Engineering from the University of Kansas in 1994. From there, he worked for Beech/Raytheon Aircraft, starting in design but quickly moving to the Structural Dynamics and Acoustics Group before leaving the company to start an Acoustics Group for Nordam, an aircraft interiors supplier. After this, Mr. Cerjan became a full-time consultant working for Hankard Environmental Inc. for about 20 years, and has also worked with Michael Theriault Acoustics during this time. He has conducted hundreds of noise studies and noise modeling projects throughout his career, as well as provided presentations and testimony on behalf of his projects. Shelley Morton has worked with Jeff for the past 10 years, supporting noise studies while bringing her GIS and environmental expertise to significantly improve our final products.

Frequently Asked Questions
Q: What geographic areas does Cerjan Acoustics serve?
A: While Cerjan Acoustics maintains primary offices in Central Colorado and South Florida, our engineering team is not limited by geography. We travel nationwide and internationally to perform complex environmental noise studies, sound modeling, and industrial compliance testing for clients across the United States and worldwide.
Q: What industries require specialized acoustic engineering and noise modeling?
A: We provide rigorous noise measurements, SoundPLAN modeling, and compliance studies across a wide array of heavy industries. Our primary sectors include traffic and transportation infrastructure, renewable energy (wind and solar farms), crypto and data centers, traditional mining, gas transmission and compressor stations, liquified natural gas (LNG) facilities, power stations, and government/public sector contracts.
Q: How are baseline noise measurements and environmental noise models conducted?
A: Professional noise assessments require high-precision equipment and adherence to strict standards set by ASTM, ANSI, and ISO. We perform short- and long-term sound monitoring, define exact source levels, establish background ambient metrics, and utilize advanced software like SoundPLAN (implementing standards such as ISO 9613-2) to map precise noise propagation for land development and industrial compliance.
