Run Time The overall time of your noise study Weighting A and C weighting are types of frequency filters that cover the frequency range of human hearing A C 20Hz to 20 kHz e A weighting The A weighted filter attempts to make the dosimeter respond closer to the way the human ear hears It attenuates the frequencies below several hundred hertz as well as the high frequencies above six thousand hertz A weighted measurements are often reported as dBA C weighting provides a fairly flat frequency response with only slight attenuation of the very high and very low frequencies C weighting is intended to represent how the ear perceives sound at high decibel levels and is often used as a flat response when LINEAR is not available C weighted measurements are often reported as dBC Table 3 1 Dosimeter parameters and definitions continued 053 644 Rev E Page 20 eg4 amp eg3 21 Views on the Edge Definitions of data log values and views Views on the Explanation Edge Memory storage symbol eg4 The eg4 model displays the total memory storage remaining in hours and minutes For example if it displays the memory symbol 181 50 this represents 181 hours and 50 minutes of memory storage remaining on the dosimeter eg3 The eg3 model displays the memory by indicating the remaining number of studies it will store into memory For example if the eg3 displays 50 this indicates you can store 50 studie
