Why can I hear tapping in my walls?
A repetitive ticking or clicking sound coming from walls and ceilings can result from the expansion and contraction of metal HVAC ductwork that conducts ventilation through these voids. When metal heats up, it expands; when the furnace stops pushing warm air through the system, the metal cools and contracts.
Why do I hear knocking in my walls at night?
If it’s very rhythmic tapping, it’s usually pipes or air ducts heating up or cooling off. As the metal heats or cools it expands and contracts and sounds like tapping or creaking. The house settling can make tapping sounds but that is usually more random, less rhythmic sounding.
Why do I hear banging in my walls?
Homes make a lot of weird sounds on the own at given times of the day, often because of structural shifts or mechanical reasons. A knocking or banging in the walls usually occurs when water faucets are turned on and off. It creates a “pressure hammer” because pressure builds up in the pipes that vibrate once released.

The audible noise emitted from high-voltage lines is caused by the discharge of energy that occurs when the electrical field strength on the conductor surface is greater than the ‘breakdown strength’ (the field intensity necessary to start a flow of electric current) of the air surrounding the conductor.
