A sound foundation
Cummins Acoustical Technology Center (ATC) located at the Cummins Power System factory in Fridley, Minnesota has a hemi-anechoic sound testing chamber with the ability to test and record precision-grade acoustical data from 20 Hz to 20,000 Hz… the entire range of the human auditory recognition.
Measuring at 105 feet long, 80 feet wide, and 36.5 feet high, the ATC is one of the largest of its kind in the world in diesel or power generation business and exemplifies Cummins’ commitment to innovation, precise engineering, and its dedication to providing quiet products for a sustainable future.
In tune with sustainability
The team’s commitment to innovation and precise engineering is reflected in the construction of the ATC. Despite its massive size, more than three-quarters of the materials used to build the center have been recycled or salvaged.
The building materials include recycled or partially recycled metal paneling, fly ash concrete and locally sourced material such as steel made from ore mined in northern Minnesota. In addition, the center was built on a site that qualifies as a brownfield redevelopment by the U.S. Green Building Council.
Through extensive testing at the ATC, Cummins developed the next generation of potable generators: the Onan QG 2800i, which is 62.7% quieter than the previous product line with nearly a 50% improvement on fuel consumption.
