Well - why do you think it's noisy? It certainly has a strange sound, and at the very end a kind of low frequency artefact, but it sounds band limited, low dynamic range possibly low bitrate - could be so many things, but there is no noise as such.
Explain how it was recorded - what mic, connected to what kit, and recorded by using what software - what settings did you choose - bit rate, bit depth, file type? Then we maybe can suggst something. How to do noise reduction isn't going to help?
