Hello,
we bought a middle terraced house that is currently under construction. The basement, ground floor, and half of the upper floor are structurally completed. Interior walls, except for the load-bearing ones, are still missing. Windows and doors have not been installed yet.
The house on the left is connected to us via the basement slab, but there is no connection to the middle house on the right. We visited the construction site over the weekend and performed knocking tests. Firm knocking with a piece of wood and jumping can only be heard through the open windows. However, when you hit the wall firmly with a clenched fist from the side, the dull reverberation can also be heard inside our house. It doesn’t seem to come through the open walls. This applies to both houses on the left and right. We did not notice any difference.
Is it normal to hear this kind of reverberation? Besides the 5cm (2 inch) insulation between the houses, there should be no contact points.
The building specification states the following:
“Sound insulation between the party walls made of mineral wool, thickness = 5 cm (2 inches), continuous from the top edge of the foundation slab to the underside of the roof tiles.”
Thank you for your opinions.

There were two separate houses above, 5 meters (16 feet) apart, connected only by the basement and the floor slab. If someone drilled a hole in one house, we could hear it as if the drilling was happening in the adjacent wall. There was no way to fix this, and in the end, we moved out very frustrated.
