In this paper we investigate quasinormal modes (QNM) for a scalar fieldaround a noncommutative Schwarzschild black hole. We verify the effect ofnoncommutativity on quasinormal frequencies by applying two procedures widelyused in the literature. The first is the Wentzel-Kramers-Brillouin (WKB)approximation up to sixth order. In the second case we use the continuousfraction method developed by Leaver. Besides, we also show that due tononcommutativity, the shadow radius is reduced when we increase thenoncommutative parameter. In addition, we find that the shadow radius isnonzero even at the zero mass limit for finite noncommutative parameter.
