Noise Breakers and Traditional Noise Protection
Noise Braker; This is a vented, shell style plug with a small filter inside the vent. With good attenuation and moderate clarity, this plug delivers up to an NRR* of 20 dB (CSA Class B) when made in the standard New-sil material. This is a good choice when attenuation is needed along with the ability to still hear some low frequency sound for environmental awareness.
Sentinel – Traditional Noise Mold; This is a solid shell style plug with up to NRR* 26dB (CSA Class A & AL) when made in the standard New-Sil Material. This has the most attenuation we offer in a noise plug. Sentinel is a good choice when communication is not a priority and sound attenuation is.
Noise Braker and Sentinel plugs are available with several options upon request which include: fit style (shell, 1/2 shell or canal) handles,strings, metal ball bearings (for detection purposes), clips, color swirls and even sparkles. Note: a fit style change from traditional shell may affect attenuation.
- Noise Braker and Sentinel plugs are easily cleaned by using mild soap and warm water, then left to air dry.
