Plasma density fluctuations, due to the presence of massive, charged dust particles, can alter the usual dispersion properties of waves as shown, in a particular case, by de Angelis et al. [1]. Here a general dispersion relation is derived, as an average over a random distribution of dust particles, and the possibility of complex solutions (wave damping) is pointed out.
