Have you tried Audacity's Noise Removal feature(s)?

This may be more of a 'click' than a 'noise' (looks like it), so perhaps you'll have better luck with the Audacity "Click Removal" features?

Example of what's on the page:

Sometimes an even better result can be obtained by zooming in (CTRL + 1) to near sample level and either silencing the click (Edit > Silence), or using the Draw Tool to smooth out the contours of the samples and so attenuate the click.

@Siva - I added the wiki page for the Click Removal suggestions/features. –  techie007 Apr 28 '11 at 17:32
    
it is a huge file 10 hours, so will it be practical to use this feature first of all ? –  Siva Apr 28 '11 at 18:16

In case you haven't tried them yet, Effect > Leveller and Effect > Click Removal in Audacity might work here.
