Understanding what data is stored

Summary 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

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.
