Can I Mute?

[JeffLearman]

A click on the speaker icon in the relevant track is sufficient to mute the sound from that track.

Correct, but that doesn't address the OP's question, which was how to keep others from hearing him yet allowing him to hear himself.

The answer to that is:

• Muting yourself takes your channel out of everyone's mix
  
• Use your audio interface's "direct monitoring" feature to hear yourself.
  

This works for audio channels, but not for MIDI channels (because if you mute your own MIDI track, it mutes it for you and everyone, and your audio interface's direct monitoring feature can't help in this case.)
