A dodecahedron is a three-dimensional shape with 12 flat surfaces as sides. Each of the 12 sides has five edges, meaning dodecahedrons are made of pentagons. You can demonstrate this polyhedron by telescoping straws one into another and building pentagons, then taping 12 of these pentagons to...
[Jacob] created aclever 3D printed moldthat can createRhombic Dodecahedrons. It has some rather unusual properties as it can be stacked perfectly (no gaps in between the snowdechedrons) and all opposing sides are parallel so it can be held easily in a mitten or glove. Additionally, since ...

Applying the proposed inverse filtering has many advantages: it flattens the frequency response, shortens the time response making the signal of the source more adequate for acoustical measurements and improves omnidirectionality. Inverse filtering was also utilized for other inverse horn design ...
