Product Overview

The H540A-411-SV is a Muff Headband with 42.6dB real ear attenuation and 2.6dB standard deviation. This headband features broad, soft head cushion for best comfort even when worn for long intervals. An acoustic connection between the inner volume and the volume between the casings in its turn provides maximum low-frequency muffling. The sealing rings are broad and filled with soft plastic foam for the best fit and low contact pressure. Optime-III is a super-muff and has been developed for use in extremely noisy environments.
  • Double casing that minimises resonance in the holder casing
  • High-frequency muffling
  • Easy to understand speech and signals
