Guarding workers against the daily hazards of noise is of paramount concern in countless industries. The challenge is to balance personal protection with comfort.
SNR [Single Number Rating] – This rating number is used by the European Union.In addition to an overall rating, the SNR further rates protectors in terms of the particular noise environments in which they will be used – H for high-frequency noise environments, M for mid-frequency, and L for low-frequency. Note that the HML designation does not refer to noise level, rather the spectrum of the noise. For example, a protector might be designated with SNR 26, H=32,M=23, L=14.The estimated attenuation changes according to the noise spectrum of the environment in which the protector is to be worn.
