After a few days over the weekend of observing complete absence of ELF and sub-audible acoustics from Tele-vision transmission I had noticed beginning last night that the ELF usage in some commercial Tele-vision has resumed. I have documented below screenshots from this morning in the following categories:
1. Complete or near absence of below 700hz.
2. Between 700hz and 100hz only.
3. Below 100hz anomalous.
4. Below 20hz anomalous.

Just observing before and after the period of no ELF usage in commercial programming, there has been observed a deduction of the ELF usage in Tele-vision programming, however it still demonstrates that usage in some areas of Tele-vision programming.
