Neighbors violating noise code, police refuse to enforce the code

[Dina Harleth]

Neighbors violating noise code, police refuse to enforce the code - do I have to disclose to tenants/buyers? 

I own the home that I live in. Three years ago a house adjacent to mine was purchased by a family with several kids. The family makes a lot of noise in the form of shouting, shrieking, etc. I looked up my city's noise code, spoke with Code Enforcement, and purchased the decibel meter used by them. I was able to determine that the neighbors are violating the noise code but despite the code's stating that police must measure noise and enforce the code, the police refuse to do anything about the situation.

I understand that this noise may not bother some, but I have PTSD as well as a severe chronic health/pain condition and the random loud shrieks cause a startle reaction as well as increased pain, etc. The adults also violate the code due to their very loud shouting.

The police lieutenant I've been in contact with said that since the noise is caused by children, they don't want to enforce the code. The code does explicitly state that it covers human voices, however. 

I have several questions:

1) Do I have any viable options for remedying the situation - i.e. getting the neighbors to reduce the noise?

2) If I were to rent or sell the house, would I need to disclose to potential tenants or buyers things as they currently stand?

3) If so, would I need to disclose anything if the noise were reduced to a level where it were no longer violating the code? I am assuming that if the neighbors were to move, I also would not have to disclose anything.

Thank you!
