Progressive reinforced semi-custom hearing protection earplugs Mk4 (SNR: 19 to 27db) - Pink - Alvis Audio

Reinforced Progressive Earplugs Alvis Mk4 - Alvis Audio

These reinforced progressive earplugs Alvis Mk4 by the brand Alvis Audio offer two levels of protection to modify the type of noise attenuation, either to maintain optimal hearing while capping dangerous noises, or to reduce all noises.

With the flap open, the filter allows you to stay in contact with the external environment while reducing constant noises that are too loud, which will be brought down to a comfortable sound level, and impact noises, which will be instantly reduced. This level allows for phone calls or conversation.

With the flap closed, filtration is permanent and identical across all frequencies. This level of protection is recommended for work with high and constant sound volumes or for sleeping.

These earplugs are suitable for many sectors of activities and leisure: hunting, sport shooting, motorcycling, construction, logistics, etc.

FEATURES:
- Low protection in quiet environments (4 dB at 80 dB of noise)
- Moderate attenuation in medium noise (24 dB at 100 dB)
- High attenuation in loud noises (39 dB at 120 dB)
- All sounds remain clear and precise, but compressed to a comfortable and harmless level
- Enhanced attenuation on high frequencies: + 3 dB attenuation compared to Mk3 (slightly more than double) on frequencies dangerous to hearing
- While maintaining very good auditory precision in the open position, the Mk 4 can absorb higher sound levels
- Versatile filtration that allows maintaining good comprehension of useful sounds and protecting your hearing even in very noisy situations such as sport shooting
- 2 levels of attenuation (high or very high) thanks to the closing flap
