ABOUT HESSLER

Hessler Associates, Inc. was founded in 1976 to provide consultation in engineering acoustics, principally for the power and industrial facilities industries. The firm has completed countless environmental noise assessments and acoustical design for new and existing facilities located all over the world ranging from 1000 kW diesel gen-sets up to 1700 MW combustion turbine combined and open cycle plants, nuclear power plants and renewable energy including wind and land fill gas to energy. Acoustic plant designs range from standard baseline silencing equipment to ultra-low noise designs for sensitive areas. The firm routinely provides ambient sound surveys, impact analysis and computer modeling of facilities, as well as problem solutions such as the control of low frequency infrasound from open cycle combustion turbine plants.

Prior to forming Hessler Associates, George Hessler acquired years of experience designing noise abatement systems for a leading silencing systems manufacturer, and later became the Chief Structural and Acoustics Engineer for Turbo Power and Marine Systems, Pratt & Whitney’s industrial supplier of aero-derivative gas turbines. David Hessler is the principal designer of major combustion turbine and fossil fueled plant facilities for General Electric, Bechtel, Calpine and other leading firms, and has visited and tested installations throughout the world. David is also actively engaged in over 40 large wind turbine and other renewable energy projects in the U.S. Mark Hessler is an expert at computer modeling of power plants and other facilities including waste gas facilities, landfills and quarries. Samples of Mark’s work are available under the Modeling Tab.
