Character as I break them or I regularly lose I generally use a SNR22 5 well enough to protect me from the noise.
By cons with headphones always it seems to be under water, it was the ears that heat, it is not practical with a cap or hat, he presses the arms of the glasses, we don ' not hear other sounds including colleagues on site. ..bref is effective against noise but annoying to wear, so I spend my time removing and restoring the I start or stop a machine and I finished quickly by damaging or losing.
So I tried the earplugs, it's true they are forgotten and can keep them long enough (1H / 2H a row, the longer it's been a little sore but in the ear removing the 10 minutes can then leave) and we are no longer cut off from the world. By cons, mitigation is not enough for machinery and I handed the helmet after a day of use. FYI, these caps are given to SNR19 high frequency- SNR17 average frequency-low SNR18
Yes they are given primarily for loud music, but I have not found the saws ...
