Tip request.
Does anyone know how to soundproof a wall? It seems the builders of the new apartment I moved into forgot to soundproof the wall between the bathrooms. Laddo next door, takes a shower for an hour at 11pm every night and another hour shower at 7am every morning. After his shower he will stand there and blow his nose about 3 times and then go for a shit.
He normally goes for a piss at about 3.30pm and 6.45pm. The other day he must have had a visitor or drank more than normal as there was an additional piss at 8.17pm which really annoyed me.

it's rarely cheap or easy.
sheetrock (wallboard, drywall, it has many names) comes in sound-dampening varieties. some have steel plates sandwiched between the layers to deaden noise, others use different materials. it is expensive, but if you know a builder and don't mind waiting and doing it yourself, you can ask for the smaller offcuts that get thrown away.

otherwise sound studios (or small bands in the garage) on the cheap use dense foam, styrofoam (useless unless layered with other stuff) or the classic, cardboard egg cartons. these dampen sound a little but are obviously ugly - they also eat space like mad, especially if you want your place looking good and then put wallboard over top.

a very different plan: buy a white noise machine. people typically say they sound like waterfalls and such, and can take a few nights to get used to. they do work for most people, though. alternately, buy an old fan that hums or makes a constant rhythmic noise as it spins. you get the noise that replaces the noise of the neighbour and the added benefit of air circulation, too.

gaz me if you have any questions, i don't check in here often.

I think
You're looking for solutions in all the wrong places. Instead of soundproofing the wall, why not wait for his performances and applaud, or exclaim "And that's an eight from the Russian Judge"

Then see who wants soundproofing more.

Good point
try getting him to sound proof his end, so to speak. Interrupting his bowl movements will throw him off balance for the rest of the day. Shouting words of encouragement at the right moment is the best way to get his muscles to slam shut.
