  Fuzzy Transform (F-transform) has been introduced as an approximation method
which encompasses both classical transforms and approximation methods studied
in fuzzy modeling and fuzzy control. It has been proved that, under some
conditions, F-transform can remove a periodical noise and it can significantly
reduce random noise. In this work we apply the F-transform methodology to
propose a finite-difference approach to solving the acoustic wave equation with
noisy initial conditions.
