TFW does say there is an opportunity for reduced noise. However, conventional turboprops are very loud compared to their jet counterparts.

Each revolution of a prop blade sends out a shockwave of air against the airframe. The strength of the shockwave is likely proportional to the instantaneous thrust of the engine, and more blades are likely to weaken or smooth it.

A turbofan has a nacelle to contain the shockwave, and avoid the whole noisy mess.
