Beschreibung
Zusammenfassung:	An earplug comprises a core and a sound-attenuating body attached to the core, the sound- attenuating body comprising a tip cavity extending proximally from the tip of the sound-attenuating body and comprising a distal opening. The tip cavity side wall includes a plurality of protrusions extending inwardly toward the longitudinal axis of the core. The plurality of protrusions may include from 2 to12 protrusions. A method of making an earplug includes covering at least a portion of a core with a material including unactivated foaming agent; inserting an end of the core and at least a portion of the material into a mold cavity; and activating the foaming agent to create a sound-attenuating body. The sound- attenuating body has a base, tip, and tip cavity with a plurality of protrusions. Themold cavity may include a boss with a cup and plurality of cut-outs on the cup for forming the protrusions. 本公开提供了一种耳塞，该耳塞包括芯和附接到该芯的消音主体，该消音主体包括末端腔，该末端腔从消音主体的末端朝近侧延伸并且包括远侧开口。末端腔的侧壁包括朝芯的纵向轴线向内延伸的多个突起部。该多个突起部可以包括2至12个突起部。一种制备耳塞
