Recently, Campos et al investigated the quasinormal modes and shadows of noncommutative Schwarzschild black holes. Since we know that the quintessence matter surrounding black holes has important influences on the black hole quantities, we decided to handle the noncommutative Schwarzschild black hole embedded in quintessence matter. We first examined black hole's thermodynamics regarding the Hawking temperature, entropy, and specific heat functions. Then, we discussed phase transition and its stability. Next, we predicted the shadow images in the presence of plasma. After visualizing these results qualitatively, we calculated the quasinormal modes in WKB and Mashhoon approximations and we demonstrated the impacts of quintessence matter and noncommutative spacetime on the whole quantities.
