HOW TO CHOOSE EARPHONES FOR THE WORKPLACE:

Protective, noise-reducing earmuffs protect the operator against harmful noise by lowering the sound level measured in decibels by the value of the SNR parameter. The upper limit for an 8-hour working day is set at 85 dB. If the average noise measurements at the workplace exceed this value, then you should have ear muffs with the SNR parameter, which will allow the noise level to be reduced
