Abstract: A new iterative method is proposed for the inverse problem of 2-D acoustic equation. As a kind of Newton-type iteration, the method overcomes the ill-posed of inverse problem by Tikhonov's regularization method in each iterative step and has a good numerical stability.The Numerical results show that this method is feasible and effective.

Key words: wave equation, numerical inverse problem, regularization method
