Abstract:
A hearing protective earplug for insertion into the human ear canal of a user where the human ear canal has sidewalls and a typical curved portion. A soft resilient body has a main body element with a front end for insertion in the human ear canal. An elongated stem has two ends with one end attached to the main body element. The stem extends outward from the main body element and away from the front end. The other end of the stem forms a handle portion of the stem. The stem is sufficiently stiff as to allow manipulation of the main body element into the ear canal of the user. The stem member has a crooked or wavy configuration within the ear canal as it extends outward from the main body to the handle portion of the stem. As the front end of the main body element is inserted into the ear canal, the stem member is rotated during insertion with the handle portion to fit around the typical curved portion in the human ear canal. This seats the main body to acoustically block the ear canal while at the same time spaces the stem member within the typical curved portion of the ear canal to minimize contact with the sidewalls of the ear canal.
