Castellated cosmetic mesh stiffener for acoustic flow noise reduction

An acoustic cover assembly, comprising:

• an air permeable component;
• and
• a support component engaged with the air permeable component, the support component comprising;
• a base defining an aperture;
• a sidewall extending from the base adjacent to the aperture, the sidewall comprising at least two protruding members;
• the sidewall defining an open flux area at least 10% larger than an area of the aperture and in communication with the aperture.

A method of forming a support component for an air permeable component, comprising:

• drawing a body into a shape defining a recess;
• forming multiple first apertures in the body defining the recess;
• further drawing the body to increase a depth of the recess;
• and
• removing a portion of the body defining the recess to define a second aperture and at least one protrusion adjacent to the second aperture.
