Custom-moulded earplugs
Emtec Laboratories is a UK manufacturer of the Noisebreaker custom moulded hearing protection, and have supplied many companies and individuals over the past 40 years.
The Noisebreakers are made from a medical-grade soft silicone rubber and are said to be very comfortable. They have a through channel with a filter allowing speech frequency sounds to be heard, but filter out the damaging middle-high frequencies.
Because of the through channel in the “ear plug” a person is not completely isolated from his/her surroundings and conversations and warning signals may be heard.
As custom-moulded earplugs are made from a soft silicone rubber, they are a suitable fit to each ear, thus alleviating any problems of poor fit or discomfort, giving laboratory attenuation in the ‘real world.’
Custom-made earplugs such as Noisebreakers can be comfortably worn under helmets or breathing apparatus. With a long life expectancy and no moving parts to wear out, such products are very cost effective over time.
