I reckon you could get a nice borer to at least the third upright (everything is looking jolly healthy so why not add some more plants to soak up the noise) maybe if you dug it out you could put some gravel as a sub base to help drainage. Where the slope sharpens off after the third upright you could plat some bamboo (in pots) and bury them. Or trellis and climbers would help deaden the sound and be pretty light work.
