**What does TLH mean?**

TLH stands for

**T**otal

**L**istening

**H**ours. It is a metric for measuring the amount of time spent listening to a radio station and is often used by music licensing authorities for royalties reporting. Its also a good metric for working out how popular a station is by giving the total amount of time over a designated period that your station was listened to.

So for example, a TLH of 150 hours could be achieved by 15 listeners tuning in for 10 hours each, 150 listeners tuning in for 1 hour each, 1 listener tuning in for 150 hours, 30 listeners tuning in for 5 hours each and so on.

How is the TLH calculated?How is the TLH calculated?

The TLH is calculated using the following equation:

(Number of listeners x Listener minutes) ÷ Minutes in an hour = Total Listening Hours

So for example, if you had 27 listeners tuning in for 17 minutes each this would be calculated as:

(27 x 17) ÷ 60 = 7.65 (Total Listening Hours)

__How do I find my TLH reports?__In the Centova Cast control panel, you just need to go to the 'Reports' section from the side navigation bar.

Next, you will need to change the reporting period to 'Custom' to specify any required dates. So for example 'Feb 21st 2015 to March 23rd 2015'.

Next, navigate to the 'Historical' tab.

Under this tab you will notice various graphs. You will want the 'Listener Minutes' graph in this case. Next to this graph the reporting period dates are displayed. Below this is the "Total Minutes" which provide the total number of listener minutes during the specified reporting period. Also provided is the hourly and 24 hour average of listener minutes.

In the above screenshot example, we can see that the 'Total Minutes' on this account for 'Feb 21st 2015 to March 23rd 2015' equates to 3,708,812. So to calculate this examples TLH for this period, we just divide the 'Total Minutes' by 60 (minutes per hour) to get the Total Listening Hours.

3,708,812 ÷ 60 = 61,813.56 (TLH)

A spreadsheet can also be downloaded with the 'Download' button which breaks down the listener minutes by the hour and gives each minute of listener time for that hour. To calculate the TLH for each hour just divide this by 60 (minutes per hour) again and will you get the TLH number.
