-
Approximately 5 minutes per person. We take an impression of your ear. A small foam stop is placed into the ear canal and the silicone is gently squeezed into the ear to make the custom ear plugs.
-
The custom ear plugs are made from a Hypo-Allergenic medical grade soft silicone (shore hardness 25).
-
Vented - A channel through the earplug contains a passive acoustic noise filter. This is an inverted cone of precise dimensions that allows certain wave amplitudes to pass through, but attenuates the hazardous industrial noise, whilst allowing the user to hear speech, shouted warnings and to use phones and radios. Vented is 29SNR.
Solid - This does NOT have a channel, providing additional protection in extreme noise environments. Solid is 31 SNR.
