Import the track, select all using ctrl + A, use space bar to start
playback, and, while it's playing, use first the [ key and then the ]
key to mark start and end of a selection of as close as possible to just
the hissing sound.
Then use space bar to stop playback, and under effects menu, look for noise reduction, and when you activate it the first time, it should come up focused on the noise sample button, which will try to extract a sample from the selection you just applied.
Once that's done, use ctrl + A to re-select the whole track, and, bring up the noise reduction effect dialogue again, and, now activate the ok button to apply it across the track, hopefully having removed the noise somewhat.
This is the simple/basic version - give it a go, and, let know if helped at all.

Just getting into editing audio in Audacity. I have a file with a lot of hiss
on it. Can somebody explain in simple English, i’m a bit of a thicko, how to
remove hiss using noise reduction in Audacity? I’m sure it’s a lot easier than
it seems. Many thanks
