Sound amplifier, you can buy them on Amazon. Enables you to hear sounds at a distance of 100 meters. They are pretty cheap too, I could hear someone whisper at 30 meters.

No, it wont pick up wall vibrations. It needs a clear line of sight.
If you want to hear your neighbors bang, use a stethoscope
