Every now and then, if your room is quiet enough you’ll hear a random cracking sound that seems to come from the wall. Why does it do that and what is happening when it does? Why are some ‘cracks’ louder than others?

Is is from the shifting if the house on the foundation. This is caused by many factors like wind or settling but mostly it is due to the change in temperatures. When the weather gets cooler or warmer it causes the materials that make up the building to warm or cool at different rates and expand or contract. The outside of the house will cool or warm faster than the inside and expand or contract against the inside. Those cracking sounds are from that.
