AB  - The simulation of room acoustics using the Digital Waveguide Mesh method has gained interest in the last years. One of the problems of this method is the frequency and angle dependent dispersion. In order to reduce this effect, an oversampling is usually employed but at the cost of highly increasing the resulting computational cost and restricting the simulation to lower frequencies. In this paper, a subjective analysis is carried out; where different oversampling factors in voice band simulations have been performed and evaluated by a set of listeners. Some listening tests employing ABX methodology have been used to evaluate the subjective effects, obtaining some preliminary results that, almost not being conclusive; they represent a first approach to the problem.
