Say goodbye to uncomfortable ear muffs that not only get hot and sweaty but can also get in the way of prescription and protective eye wear.
Variable sound reduction is achieved using a non-liner filter inserted into the pre-drilled canal on your lab manufactured custom plugs. This filter attenuates as sound pressure increases, which causes the filter to restrict sound pressure (loudness) as it increases instantaneously. No electronic components are required. The non-linear filter also reduces the occlusion effect (blocked ear sensation) and allows you to perceive a more open ear or natural effect whilst wearing plugs.
We supply “stoppers” with all Non Linear Filer plug orders – the stopper enables you to plug the hole for more noise reduction when a continuous reduction is desired.
- Attenuation (sound reduction): up to Class 4 28-30dB(A) to a Class 5
- Life Span: Approx 5 years (differs for each individual)
- Turnaround: Approximately 2-4 weeks.
