Problems with kitchen drainage

The noise is transmitted from the pipe, the sound insulation material may not be very effective, first see if there is a water trap on your drainage branch, the water seal in the trap can help to reduce the water flow noise, if not, you can add one to the water pipe under the cabinet, without destroying the cabinet.

Oh the decoration master is right, the pipe for washing vegetables is easy to block, too long to do it, and if you make the hose is not good, walk outside, the first step is good-looking, the second, easy to break, but if you have to install it there is not impossible, very troublesome, go dark pipe, installed in the ground, with PVC pipe, but it must be easier to block, and the installation is very troublesome, the decoration is not good, and, in case the pipe leaks inside, it is even more troublesome, I met a situation like yours, Installed here, and then blocked once, dredged the pipe broken, leaked, upstairs to find it, and now the floor is to be pried all the way, re-waterproof, and re-change the pipe. So I personally recommend that you listen to the decorator.

The ventilation holes on the roof must be left to prevent odors from squeezing into the bathroom.
