Can you hear the sound upstairs in the hotel downstairs?

Talk upstairs at night and you can hear it downstairs. At present, the sound insulation effect of buildings is not very good At night, the environment is quiet. If the noise upstairs is particularly loud, you may hear it downstairs, but you may not hear it clearly. This requires our residents to talk as quietly as possible when talking or having other noisy activities, so as not to affect the neighbors downstairs, and may also reveal the secrets and privacy of our family.
