Blaze Software Provides simple to highly detailed pre-formatted reports. The most popular formatted reports include (partial list - varies depending upon instrument & type of data stored): General Information report (overall data): - Compare multiple dose, projected dose & TWA with different exchange rates, thresholds, etc Summary report (overall exposure data with graph of time history): - Compliance data & graph of the levels throughout the day all one on page Modified Summary report: - As above, with modifications to sections of data – remove non-work related exposure, show proposed engineering controls, effect of de-rated NRR’s, etc Detailed Event Report Show only those times when the noise levels have exceeded a point of interest: like Leq (Lavg) >90dB, Lmax > 115dB, Lpk > 140 dB (all user selectable)

Advanced features provide higher-level analysis of the work environment with additional annotation as needed: Removal of artefacts & non-work related exposure Exposures re-calculated for exact shift length Adjustment of levels to represent proposed engineering or administrative controls Direct comparison of simultaneous exposures from >1 worker on graph Annotation of graphs with notes for better understanding
