What is TLH and SL?
TLH is Total Listening Hours. This is the number of collective hours that people listen to your station. If one person tunes into your station for one hour, that’s 1 TLH. If two people tune into your station for one hour each, that’s 2 TLH, and so on. Keep in mind, these are listening hours, not broadcast hours. TLH is calculated to the nearest minute. SL is simply the number of simultaneous listeners tuned into your station.
