Best ear protection for loud machinery
For extra sound attenuation, earplugs can also be used in conjunction with earmuffs.
The head-band and outer covering is usually made from a hard thermoplastic or metal.
The protection usually comes from acoustic foam – this absorbs sound waves by increasing air resistance, thus reducing the amplitude of the waves..
