Mr. Mueller is a principal of Ostergaard Acoustical Associates and a licensed acoustical professional engineer. He oversees on-site acoustical testing, analysis, and the development of solutions for environmental, industrial, and architectural projects. He also provides scientific counsel. Project expertise across the Tri-State area and nationwide includes:

3-Dimensional Environmental Acoustical Evaluations
Evaluation of existing and future site emissions from commercial and industrial facilities. A thorough approach traditionally includes on-site acoustical testing, development of 3-D acoustical models, development of noise control solutions, and expert witness testimony for planning / zoning boards. Representative clients major public utility companies, pharmaceutical campuses, and major logistics facilities across the country.
Manufacturing and Occupational Noise Exposure
Evaluation of noise in manufacturing environments, and identification of noise control measures to conserve hearing and create workable acoustical environments. Solutions are developed for individual equipment or whole facilities as appropriate. Clients served include Boehringer Ingelheim Pharmaceuticals, Inc., Johnson & Johnson, Philadelphia Gas Works, Gerdau AmeriSteel, OraSure Technologies, and DePuy Synthes.
Interior Acoustical Evaluations
Consultation regarding interior HVAC system noise including analyses for noise-sensitive spaces such as board or conference rooms, laboratories, and classrooms. Consultations also include the design, specification, and final tuning check of masking sound systems for commercial facilities.
Noise Complaint Evaluation and Resolution
Application of acoustical expertise to assist with evaluation and resolution of interior and exterior noise complaints ranging from nighttime trucking operations to office mechanical rooms. Optimized solutions are recommended that balance cost, feasibility, and noise reduction.
Generator Noise Control
Assistance with the design and specification of custom acoustical barriers and enclosures for emergency generators to meet noise code limits and minimize the potential for noise complaints. Generators range in size from smaller than 100 kW to as large as 2.5 MW for various sites including hospitals, electrical substations, pharmaceutical campuses, and telecommunication shelters.
Construction Noise Mitigation Plans
Acoustical evaluations to estimate construction noise levels using the Roadway Construction Noise Model (RCNM), and development of noise mitigation plans to meet project goals specified by PANYNJ or others. Acted as Noise Control Officer (NCO) for the Bayonne Bridge Navigational Clearance Project and others.
