Leq measurement - how long is the time interval

[IXIRampageIXI]

Good morning.

While playing around with the SPL logger feature of REW the other day, I discovered the function to measure the equivalent continuous sound level (Leq) in addition to Leq1m and Leq10m. As far as I understand it correctly, the Leq measurement should have a certain time interval just like Leq1m and Leq10m. How long is this interval? Does anyone of you know its length?

Best Regards
Tobi

That figure is over the interval shown as "Elapsed time" on the SPL meter, it can be reset using the Reset all button,

Thank you John for the quick reply. That makes perfect sense. I'm a big fan of rew, by the way.
