Abstract
This paper presents a procedure for reducing diesel engine sound levels by combining analytical models and test data. Four elements previously analyzed individually; 1) structure modal characteristics, 2) forcing functions, 3) dynamic response, and 4) acoustical radiation were combined to accurately predict changes in diesel engine sound levels due to structural modifications.
