Noise attenuation kit for the HGU and SPH helmet earcups. The Quiet Kit consists of four die-cut Visco-elastic foam pieces and two Valtex cloth foam covers. The denser and thicker visco-elastic foam is a popular alternative to the standard foam installed in the earcup used to provide passive noise reduction.
