ABSTRACT:
A method of forming an earplug is provided including removing a material of the earplug by laser ablation. An earplug is positioned proximate a laser, a portion of the earplug to be ablated is identified, the laser is activated so as to direct an emitted laser light toward the portion to be ablated, and the portion to be ablated is removed by laser ablation. The invention is also directed to an earplug including a feature formed by laser ablation.
