I'm sorry to hear this but I can also relate. I live in a condo on the second floor and each building is 3 floors so I'm in between floors. I've had to deal with very noisy adults for many years. The couple who live above me walk very heavy and even though they don't have children they do have a lot of relatives that come over and they let the children run wild and scream etc. This also usually happens during the summer.

I know that some times my cats will make some noise but it's nothing compared to screaming kids or very loud adults. I wish that I at least lived in a townhouse so I wouldn't have any one above me or below me. I hope that you'll be able to have some peace and quiet soon. Good luck.
