Hearing through a wall is a technique that allows you to listen to sounds on the other side of a wall. This can be useful for a variety of purposes, such as eavesdropping on conversations, detecting hidden objects, or finding leaks. There are a number of different ways to hear through a wall, each with its own advantages and disadvantages.
One common method is to use a stethoscope. A stethoscope is a medical instrument that is used to listen to sounds in the body. It consists of a tube with a diaphragm at one end and earpieces at the other. To use a stethoscope to hear through a wall, simply place the diaphragm against the wall and listen through the earpieces.
