Noise Dosimeters
Scantek Inc.'s two new noise dosimeters from CESVA, the DC-112a and DC-112k, both comply with the ANSI S1.25-1991 Class 2 standard and are designed to protect workers against exposure to noise. The instruments allow the use of frequency weightings, time weighting, and exchange rates, and measure simultaneously using two programmable threshold levels.

Attenuation Study
A recent field attenuation study by Howard Leight's Acoustical Laboratory found that one-on-one training is the most significant factor in predicting good ear plug performance. Of the more than 100 workers tested, one-third achieved attenuations higher than the published NRR for their ear plugs.
