A new lattice gas model for sound propagation in one space dimension is proposed. This model has zero truncation error, and the group velocity is independent of wave number as is required from the continuum limit. Conventional finite difference approaches do not have these properties in general. Boundary condition treatments, applicable to the lattice gas formulation, are also given. Both the boundary between two fluid media and an impedance boundary are considered.
