The noise mainly comes from the tip of the rotor blade [1]. Reducing the noise from these tips is an active research topic and some progress is established [2]. However, it seems difficult to maintain high efficiency when attempting to reduce the noise levels. In any case, scientists and engineers are trying to tackle it!
