Jimmy has given a good information. Timber flooring looks antique. It is also defined as a style statement. It requires high maintenance and care. There are nice carpets in a wooden texture available in market which gives you the same feeling as timber flooring.
If the noise still comes, check whether there is any leak or break between flooring, or might be the carpet may not be fitted properly, and if noise is still coming call the company from whom who you had repaired your flooring.
