Hearing impairment caused by noise has always been the most widespread occupational injury. As it comes gradually without no pain, the significance of hearing protection can be easily neglected. Only those who have ever been through know the importance of normal hearing and put hearing protection in the first place.
Hearing Protection: Choose products according to SNR value
Objective= Noise level - SNR
