When you are running noise dosimetry studies, there are two types of
data stored on the dosimeter which include the summary data and time
history (or Logged) data.
Summary Data
Summary data represents values that occurred over the entire run of the
study. For an average value, such as Lavg, it represents the average
decibel value over the entire run time. Peak and Max values are the
highest measurements that occurred throughout the run time.

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.
