Filtre protection auditive musique (DM)
The DM series of music filters provide state of the art hearing protection while maintaining clarity of sound. The combination of air flow and flat attenuation permits conversations to be heard without removing the filter while still enjoying the full music dynamic without muffling or loss of sound at higher frequencies.
All frequencies are reduced by almost the same level, great for music as the listener loses none of the original sound, it’s just brought down to a safe level.
Black filter has an attenuation of 20 dB.
