This is louder than a jackhammer at a distance of 1 m (3 ft 3 in). Burped speech
It is possible to voluntarily induce burping through swallowing air and then expelling it, and by manipulation of the vocal tract produce burped speech. While this is often employed as a means of entertainment or competition, it can also act as an alternative means of vocalisation for people who have undergone a laryngectomy, with the burp replacing laryngeal phonation. This is known as esophageal speech. Other animals
Many other mammals, such as cows, dogs and sheep, also burp. Ruminants
Much of the gas expelled is produced as a byproduct of the ruminants digestive process. These gases notably include a large volume of methane, produced exclusively by a narrow cohort of methanogenic archaea in the animals gut; Escherichia coli (E. coli) and other bacteria lack the enzymes and cofactors required for methane production. A lactating cow produces about 322g of methane per day, i.e. more than 117 kg per year through burping and exhalation, making commercially farmed cows a major (37%) contributor to anthropogenic methane emissions, and hence to the greenhouse effect. 95% of this gas (wind) is emitted through burping. This has led scientists at the Commonwealth Scientific and Industrial Research Organisation of Perth, Australia, to develop an anti-methanogen vaccine to minimize methane in cow burps.One reason why cows burp so much is that they are often fed foods that their digestive systems cannot fully process, such as corn and soy.
