Embodiment Construction

[0039] The disclosed embodiments can provide hearing protection in moderately noisy environments (e.g., effectively protect against noise in the range of 80 dB to 100 dB), wherein an NRR of between about 20 and 30 is sufficient to adequately protect against hearing impairment For protection and / or to meet OSHA or other workplace regulations. Furthermore, the disclosed embodiments may provide flatter sound attenuation across a range of frequencies so that users in moderately noisy environments may be protected, but still be able to hear some desired sounds (by way of a non-exclusive example, such as colleagues or a supervisor's shout). Additionally, the disclosed embodiments may provide reduced soiling and / or the ability to be cleaned, which may allow for increased useful life for disposable earplugs. And the disclosed embodiments may provide press-fit insertion of the earplug into the user's ear canal without the need for thinning the earplug, while preferably also providing ...

Abstract

Embodiments disclose a non-roll foam EarTip that may provide for fingertip press-in insertion, improved comfort, simplicity of use, flatter attenuation and/or improved hygienic properties, by way of non-exclusive example. A hollow foam body typically encompasses a shorter stem of more rigid material, and in some embodiments the foam body has a tighter skin on the inner and outer surfaces. In some embodiment, the EarTip is an earplug formed of polyurethane foam with a dense skin on the inner and outer surfaces of the hollow body, and having a plurality of splines in the cavity.
