A seal plate attachment for earmuffs. The seal plate attachment has a first and second portion including substantially flat surfaces, outer perimeters, and inner perimeters defining central openings. The first portion of the seal plate attachment includes a first channel extending around a section of the outer perimeter. The seal plate attachment second portion includes a rim, projecting inwardly from and extending around a section of the outer perimeter. The rim of the seal plate attachment second portion forms a second channel to oppose the first channel on the seal plate attachment first portion, allowing the second portion to be slidable relative to the first portion. An improved earmuff design includes rigid earcup elements, a connecting band, and soft sealing elements in combination with the seal plate attachments for earmuffs. |
