Abstract
Embodiments may be generally directed to a system for generating reactive acoustic energy for reducing acoustic noise in a chassis of an information handling system. A set of acoustically reactive elements may be positioned relative to a backplane comprising a plurality of backplane openings. Each acoustically reactive element comprises a plurality of walls and an acoustical energy reducing opening. The plurality of walls define an internal volume, wherein at least one wall is aligned parallel with a direction of airflow. The acoustical energy reducing opening may be oriented substantially parallel with the direction of the airflow and configured for the airflow passing the acoustically reactive element to pass the acoustical energy reducing opening to generate acoustic energy at a frequency based on the set of parameters of the acoustically reactive element.
