Sounds Like The Ceiling Is Falling

[Andy Ballew]

Hi BP community! Hoping someone can offer some ideas on how to resolve this challenge. I have a two story duplex. Those downstairs can hear every single step the upstairs tenant makes. Additionally, those downstairs can hear the upstairs tenant's TV/radio and some conversations. It's worth noting that those upstairs aren't stomping, yelling or playing their music/TV at unrealistic level. I am looking for ideas on how to prevent sound from traveling so freely down to the first floor. As you an imagine the sound from the second floor will drastically reduce my future pool of tenants. 

Open to any and all ideas. 

Thanks!
