ABSTRACT:
A noise-blocking banded earmuff wherein the earmuffs (12, 14) are fixed against rotation about a horizontal axis (34) with respect to the band (24), and wherein the band can extend upwardly around the top of the head, downwardly (24A) around the neck, or rearwardly (24B) behind the head, using earmuffs of moderate size. Instead of each earmuff aperture being of a vertically elongated oval shape, each aperture has four 90.degree. concave corner segments (46-49) lying at the corners of an imaginary square (36), and four connecting segments (41-44) that each connects two concave segments. The middles (56) of the connecting segments lie closer to the aperture axis (34) than the middles (50) of the concave corner sections. The connecting segments can be largely straight to form an earmuff aperture of largely square shape with rounded corners. The connecting segments can be convex (181-184) to form an earmuff aperture of largely cloverleaf shape. The shell (70) of the earmuff can have a pair of horizontally-spaced grooves (76) that each extends vertically in an initial orientation, with mounts lying in the grooves and pivotally connected to the shell.
