Howard Leight QuietDose

The new QuietDose system from Howard Leight provides the ultimate in accuracy for assessment of personal workplace noise risk.

QuietDose is the first noise level monitoring system that uses in-ear dosimetry to measure every sound that reaches the user’s eardrum. Dramatically more precise than existing area or personal sampling devices currently in use, QuietDose provides previously unattainable and highly precise data points that allow both workers and management to make the smartest, best-informed hearing protection decisions. QuietDose data equips safety managers to:

• determine whether workers are using their earplugs or earmuffs correctly

• track and address the potential of noise-induced hearing loss (NIHL) in real time

• potentially eliminate dual protection

• provide workers more appropriate hearing protectors

• streamline worker deployment by matching shift hours with proper protection more accurately

The QuietDose system consists of a small Exposure Smart Protector® (ESP) Dosimeter that’s worn by employees in a shirt pocket or on the back of a hardhat; protective eartips or an earmuff with integrated microphones that record real-time in-ear noise levels; and a connecting harness.  An infrared reader enables safety managers to retrieve data from the ESP Dosimeter at the end of each shift or work week and analyze the results on a personal computer.
