The model for the lattice dynamics of metals, recently proposed by the authors is improved by incorporating a wave vector dependent screening parameter and also a new form of the potential energy. With these innovations the dispersion curves for phonons along [100], [110] and [111] directions are calculated. The theoretical curves still do not agree with the experimental data. The results are discussed
