The patented hearing protection of the Protos® Integral provides a noise reduction of SNR=26 dB, thus creating a safe level. By meeting the standard EN 352-3, the hearing protection is indispensable for all work with disruptive or harmful noise. If the hearing protection is not required, it can be easily shifted between the active and passive positions using two fingers. The hearing protectors can be (un)clipped easily with two fingers.
To maintain the noise absorption values, the Absorption Inserts should be replaced every 2–3 years and the Support Pad should be replaced every six months for daily use.
