The Emtec Noisebreaker

The NOISEBREAKER® which carries BS 5108 and the CE Mark has been called, 'The world's finest Ear Defender against noise at work and recreation.' The company carries the standard ISO 9002.

The fact that NOISEBREAKERS® are individually tailored has a number of advantages; namely they are comfortable and therefore achieve a high level of acceptance by the wearer, in contrast to the conventional disposable plugs and ear muffs. Also they allow the wearer to communicate easily, but at the same time afford excellent protection.

The Emtec NOISEBREAKER® is a personally moulded and vented earplug. It is a silicone rubber moulding which is moulded to each individual concha bowl and ear canal. The plug incorporates a central drilled channel in which a filter is placed which allows pressure equalisation but prevents a finite impedance 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 1kHZ-6kHZ). Because of the through channel in the "ear plug" a person is not completely isolated from his surroundings and conversations and warning signals may be heard.
