The noise made when you burp comes from gas that is trapped in your stomach and upper oesophagus when the food pipe is shut. This gas is under pressure, especially when there is a lot of it. As the pressurised gas flows up the food pipe, over the surface of the upper esophagus and past the epiglottis, it makes the surface of the upper part of your oesophagus rattle and vibrate.

Where does the gas come from? The gas comes from a few different places. It can be from air that you swallow when you eat and drink which ends up in your stomach.
