Abstract
An actuator housing can be configured to function as a passive, broadband acoustic absorber by incorporating a micro-perforated panel with an array of sub-millimeter pores. The geometric parameters of the pores, such as diameter, panel thickness, and porosity, can be tuned to adjust acoustic impedance for certain noise frequencies. Such a configuration can allow the housing to dissipate acoustic energy as heat through viscous friction within the pores, which may mitigate the generation and radiation of parasitic audible noise from the actuator.
