Abstract
The structural vibration modal parameters have to be optimize for any noise and vibration reduction aim. This paper shows the use of acoustic intensity to make a 4-cylinder diesel engine block experimental modal analysis. The results obtained by the acoustic intensity for natural frequencies were compared to the classical experimental modal analysis.
