This application containing the best collection of burp sounds for android devices. Sounds have been selected very carefully to be a good and fun user experience, we hope you will enjoy using the app and listening to burp sounds. 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.
