I live in such a building in San Francisco. At most I can faintly perceive a baseline. I think the difference is mid-rise vs. high-rise, probably having to do with the use of wood vs. steel and concrete. I also run a box fan almost all the time, so quieter sounds from neighbors are below the noise floor and not perceptible.
