Figure 3 2 Sample summary data from DMS reporting Time history Time history data is also referred as logged data which plots measurement values in minute by minute intervals Time History data represents values that occurred over the most recent time period which is the logging interval For example if the log interval is 1 minute then the Peak value is the highest Peak value for that 1 minute and the Lavg value is the average dB value for that 1 minute Figure 3 3 Sample time history data or logged data chart Views on the Edge Logging Logging eg5 model only logs at one minute intervals and includes the following measurements e Meter 1 logs Lavg Leq e Meter 2 logs Lavg Leg Meter 3 logs Lavg Leq Lcpk and Lmax e Lc a if enabled If the dosimeter runs for one hour then it will log 60 Lavg Leq results and 60 Lmax Lcpk levels In DMS you can customize the logged data chart results by checking Lavg Leq Lcpk and or Lmax measurement values Views on the Edge The Edge is a user friendly and customizable dosimeter With a simple click of a checkbox in DMS you can select the appropriate measurement values or views to appear or not appear on the display of your dosimeter The following table briefly identifies the displayed data values and views with a brief definition See the glossary for additional information of these terms Definitions of data log values and views To set up the Edge and work with noise

Example Assume the threshold is set to 80 dB and the Exchange Rate is 5 dB the settings of OSHA s Hearing Conservation Amendment Consider taking a one hour noise measurement in an office where the A weighted sound level was typically between 50 dB and 70 dB If the sound level never exceeded the 80 dB threshold during the one hour period then the Lavg would not indicate any reading at all If 80 dB was exceeded for only a few seconds due to a telephone ringing near the instrument then only those seconds will contribute to the Lavg resulting in a level perhaps around 40 dB notably lower than the actual levels in the environment Lep d Daily personal noise exposure level Leq Equivalent Level The true equivalent sound level measured over the run time The term LEQ is functionally the same as LAVG except that it is only used when the Exchange Rate is set to 3 dB and the threshold is set to none 56 Appendix B Logging Also called Data Logging Certain measurements such as average level Lavg and maximum level max can be recorded by the dosimeter at regular intervals For example A dosimeter is set to log Lavg and max at one minute logging intervals If the dosimeter runs for one hour then it would log 60 Lavg results and 60 max levels You would be able to see the average and maximum levels for each minute of the one hour run time Maximum Level Lmax The highest sampled sound level during the instruments run time allowing fo

17. how the dosimeter operates and processes 3 Overview Range of sound Range of sound Sound pressure is measured in decibels or tenths of a Bel Sound pressure level is indicated as dB SPL Since the human ear can detect sounds with an extensive range of amplitude a decibel scale is used to simplify the measurement results For example the ratio between the threshold of hearing and threshold of pain in the human ear if measured in true energy is 10 000 000 times The same range using the dB scale is 0 140 dB referenced to 20 uPa Micropascals The quietest sound that humans can hear has an amplitude of approximately 0 dB Prolonged exposure to sound pressure levels exceeding 85 dB can cause permanent damage to the ear Sound levels in excess of 130 dB are more than the human ear can safely withstand and can result in serious pain and permanent damage What do the standards say Many organizations have studied and analyzed the effects of high sound exposure on hearing As a result standards were developed to regulate personal noise exposure In the United States the Occupational Safety and Health Administration OSHA the Mine and Safety and Health Administration MSHA and the American Conference of Governmental Industrial Hygienists ACGIH have all created regulations and limitations on total permissible noise exposure International standards are specified by the health and safety regulations such as the European Union EU Directiv
