For the past 40+ years Emtec Laboratories have been the market leader in custom-made hearing protection. The Noisebreakers are a personally moulded and vented silicone earplug, tailor-made to each individual concha bowl and ear canal. The Noisebreakers can be comfortably worn all day in combination with other PPE, e.g helmets, safety glasses and breathing apparatus. They do not over isolate the wearer and the in-built acoustic filter allows instructions and warnings to be heard. With an effective life expectancy of well over 5 years, they are a very cost effective solution, that is environmentally friendly.
