Noise-suppressing ear muffs comprising:
- a) a headband having first and second, laterally spaced ear piece attachment bands;
- b) first and second ear pieces in the shape of automotive tires, each having inner and outer opposite circular sides and a cylindrical outer surface extending therebetween about the circumferences of said inner and outer circular sides, said outer side of each ear piece having a radially outer annular tire portion and a central hub portion;
- c) means removably attaching said first and second ear pieces to said first and second ear piece attachment bands, respectively, with said inner sides of said ear pieces facing inwardly toward each other and said outer sides of said ear pieces facing outwardly away from each other;
- d) first and second circular discs each in the shape of a hubcap of an automotive tire;
- and
- e) means removably attaching said first and second discs into the central hub portion of said outer sides of said first and second ear pieces, respectively, with said discs lying in planes perpendicular to a respective said cylindrical surface.
