The location of the 14th floor is some distance away from the source of the sound of square dancing, and the volume of sound propagation will gradually decrease. If the building's windows or doors are not well insulated, or if there are other sources of noise in the vicinity, the sound of square dance music may be heard.
But if the windows or doors on the 14th floor are better soundproofed and the surroundings are relatively quiet, the sound of square dancing may not be heard.
It also has to do with an individual's auditory sensitivity. Some people may be more sensitive to sound, and may be able to detect sound even if it is slightly farther away, while others may be less sensitive to sound, and may not be able to detect sound at a distance.
It is therefore impossible to determine whether the sound of a square dance can be heard on the 14th floor, and this needs to be judged on a case-by-case basis.
