Claims

1. Ear muffs including a pair of arm members, each arm member provided with a noise suppression portion mounted rotatably thereto adjacent a first end of each arm member and having a first portion of an attachment system located at a second opposite end of each arm member, the first portion of the attachment system attachable to a second portion of the attachment system provided on a carrier portion adapted to be supported on a wearer'"'"'s head.

2. Ear muffs as claimed in claim 1 wherein each arm member has a longitudinal opening therein to allow adjustment of the position of the noise suppression portion.

3. Ear muffs as claimed in claim 2 wherein the longitudinal opening is defined by two elongate outer portions which stand proud of the surface of the arm member and parallel to the length of the opening forming a guide depression in the arm member about the opening and extending parallel thereto.

4. Ear muffs as claimed in claim 3 wherein a threaded rod is provided extending outwardly from the rear of the noise suppression portion, associated with a rectangular bush and a threaded nut portion such that in use, the noise suppression portion is located on the inside of the arm member with the rectangular bush located on the outer side of the arm in the rectangular depression, the threaded nut portion clamping the rectangular bush in the depression and the arm member between the bush and a rear portion of the noise suppression portion.

5. Ear muffs as claimed in claim 3 wherein the noise suppression portion has a guide portion to guide movement of the noise suppression portion along the arm member.

6.
