Apartment dwellers who host noisy get-togethers: did you ever check with the residents on either side, directly above or below before or during your event if they were bothered by or could hear your noise?
The last "noisy get-together" held in an apartment, in which I personally participated, was one which the upstairs neighbours were invited to & attended. It was on a weekend, so the downstairs neighbour, an architect's office, was not affected. And the building was of the one-apartment-per-floor type, so there was no "either side" as such. One room of the apartment abuts on the building next door, but it was placarded No Admittance.
