Beschreibung
Zusammenfassung:	An ear protecting device for protecting a wearer from annoying and/or damaging noise levels. The device is comprised of a connecting member and a pair of muffs suitable for covering a wearer's ears. The muffs are suspended from opposite portions of the connecting member. The muffs are each comprised of a cup and an earseal cushion. The muffs are characterized by greater attenuation in high intensity environments than in low intensity environments. Each muff has a cup which is at least partially porous. Each muff has a specific airflow resistance of from between 3,000 and 105,000 SI rayls. At least one porous portion of each cup defines a tortuous path. The mean pore size of this porous portion is at least 160 micrometers.
