Industry / Non-Linear Filter

This filter attenuates as sound pressure
increases.
Also allows for easier
communication whilst ensuring
your hearing is protected.

Variable sound reduction is achieved using a non-liner filter inserting into the pre-drilled canal on your custom plugs.  This filter attenuates as sound pressure increases, which causes the filter to restrict sound pressure (loudness) as it increases.  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.

  • 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.
