Window exhibiting reduced sound transmission and method of making the same

A window for an aircraft fuselage, comprising:

• a substantially transparent polymer window member, configured to mount in an aircraft fuselage, having a perimeter, a thickness, opposing parallel window surfaces, and a viewing area within the perimeter;
• and
• a plurality of discrete, generally planar, transparent reinforcement regions, connected to the window member, that are (i) parallel to the window surfaces, and (ii) asymmetrically located away from the perimeter within the viewing area, the reinforcement regions selectively asymmetrically stiffening the window transmitted therethrough, wherein each of the transparent reinforcement regions extends through less than the thickness of the window member, wherein the transparent reinforcement regions are non-overlapping along a plane corresponding to the viewing area, and wherein the transparent reinforcement regions are non-overlapping along a cross-section plane corresponding to the thickness of the window member.
