ALVIS Mk4: Noise plugs with reinforced attenuation

This is not a noise plug like any other, it is the best hearing protection available: it has been designed for extreme uses, to protect your hearing without cutting you off from the world!

The difference compared to a usual plug comes from the progressivity of the attenuation:

Low protection in quiet conditions (4dB to 80dB of noise),

Moderate attenuation in average noise (24dB to 100dB),

High attenuation in high noise (39dB to 120 dB),

All noises remain clear and precise, but they are compressed to a comfortable and harmless level,

Advantage: increased attenuation on high frequencies (the most risky).

Alvis Mk 4, advantages:

Enhanced attenuation on high frequencies: + 4dB attenuation compared to Mk3, i.e. a little more than double.

Very good hearing accuracy in the open position,

2 levels of attenuation (high or very high) thanks to the closing flap,

Effective filtering of sounds without distorting them: very good understanding of human speech,

Enhanced high-frequency attenuation for high-sounding activities,

Very simple and quick to set up,

Excellent retention in the ear,

Super comfortable, to be worn all day long,

A very high performance and economical noise plug: it protects you when you need it without cutting you off from the world.

Alvis Mk4 has obtained CE certification for PPE (Personal Protective Equipment)
The attenuation values tested in accordance with EN 352-2: 2002 of Directive 89/686/ECC (These values give the attenuation level at constant incoming noise level)

ALVIS Mk4 closed SNR : 27 H : 28 M : 24 L : 24
ALVIS Mk4 Open SNR : 19 H : 22 M : 16 L : 11**
