First head over to the Noise homepage and click on the Order button to purchase a server. On the Order page, ensure you select Mumble as the server type and then select how many slots you need for your server (slots determine how many users can be logged in to your server at the same time). Also be sure to select the host location closest to you as it will provide you with the fastest connection. Enter your payment info and submit the order and your server will be instantly activated!
After submitting your order you will be redirected to the Control Panel for your Mumble server. Here you can configure your Mumble, manage its passwords, upgrade or downgrade your plan, or even move your server to a new location. You will want to get the SuperUser password to setup your Mumble so click on Manage Passwords to view it.
Next you will want to login to the Mumble client (download it here if you do not already have it) using the SuperUser password. Open Mumble and in the Mumble Server Connect dialog add your new Noise Server and for the username put SuperUser and enter the password.
Your server has now been created, and you have logged in and gained admin powers, so you are good to go! You can invite some friends in to start chatting right away, or explore customizing your Mumble server more by adding some channels and tweaking the settings.
To learn more about using and configuring your Mumble server be sure to explore the other guides in our Help Center. And for additional help on the Mumble client, check out the official Mumble Wiki.
