The R8085 is designed to calculate and display an individual's noise exposure in
%DOSE on the LCD display. All stored readings that are captured during the modes
described in this manual can be accessed, and exported to Excel for further analysis by
using the optional PC software (R8085-PC) and USB cable (R8085-USB).
What is Dose Noise Exposure?
The unit of measure, %DOSE, is used to quantify noise exposure that is
measured during an employee's work shift. 100% dose is the maximum
allowable noise exposure in accordance with OSHA, CCOHS, MSHA,
DOD, ACGIH, and ISO standards. Most standards specify what specific
Criterion Level, Exchange Rate, Response Time, and Frequency weighting
the dosimeter should be set up with in order to meet these
specific standards.
