Noisebreakers
The Noisebreaker is a custom made vented earplug. It is a silicone rubber moulding which is moulded to each individual ear and ear canal. The plug incorporates a central drilled channel in which a filter is placed which allows pressure equalisation but presents a finite impendence to the passage of audio frequency sounds.
The acoustic filter attenuates all sounds going to the ear but attenuates more in the mid-band range (approximately 1 kHz-6 kHz). Because of the through hole in the 2ear plug2 a person is not completely isolated from his surroundings and conversations and warning signals may be heard.
The Noisebreaker has no moving parts to wear out or injure the ear; can be conveniently carried in pocket or purse at all times; can be worn under headphones or helmets; is virtually indestructible, and being easily cleaned and non-disposable will (with reasonable care) be very cost effective, as they have an expected life of approximately seven years.
The key point about Noisebreakers is that they can comfortably be worn all day, and they allow the wearer to hear what is going on around them, whilst being protected from gun fire noise.
Noisebreakers are very comfortable and unobtrusive, they are easy to insert, and they cannot fall out. No batteries or maintenance needed. Comes in a variety of colours.
