Joseph:
For your thrill, just mosey over to your Rov this week, and ask him what you should do when you encounter a sofek sakanah? Should you then come ask the shailoh or should you take safety related action? Then post his response here please.
One who acts for safety, even in the case of sofek is exempt from all the halachos you push – yuour personal agenda.
Health:
I seriously doubt that the sheer decibel level of the neighbors home was distressing to where some guidance was sought (not that posting in the CR is the equivalent of asking a shailoh). If there was the belief that there was a chance of the noise indicating trouble, there is good reason to reach out to the appropriate first responders for the emergency. There are too many variables to know whether this is Hatzoloh, Shomrim, Chaveirim, Shmira, police, EMS, or fire department. What is clear is that if this is the issue, running to find your Rov at that point is neither required by halacha, nor is it responsible. Picture someone drowning. Should you try to rescue, or should you ask a shailoh? The latter is so senseless that it is offensive to make this sound like a holy thing to do.
