This paper will evaluate the standard and published data for small towers per ATC-128 with respect to usability for acoustical consultants. Through testing of fully operationally field installed units and test-stand towers some challenges and opportunities have been identified to help improve the use and accuracy of ATC-128. Using ATC-128 in the field has distinct challenges associated with height, distance, and background noise. The paper includes a comparison to ANSI/AHRI 370 the standard for Sound Performance Rating of Large Air-Cooled Outdoor Refrigerating and Air-Condition Equipment.
