Trees are harder but I think noise can be mitigated at personal levels, you just have to avoid 国道沿い(kokudo zoi, "along highways") and 線路沿い(senro zoi, "along rails") apartments. Tokyo is an impacted and upscaled melon skin, edges of Voronoi cells being roads and scars being rails. Towards the center of cells are quieter.
