Source sentences:
text: I have asked biologists why dogs and cats generally fart silently, and their theories include: (1) the amount of gas produced is small, but potent, (2) the horizontal orientation of their gastrointestinal system puts less pressure on the anal opening, so the gas is expelled more slowly, (3) their anal sphincters don't close as tightly as humans' because it takes less force to hold in the contents of the colon -- again because of the horizontal orientation of the gastrointestinal system -- and a loose anus makes less sound, and, my favorite (4) dogs and cats don't feel embarrassed about farting, so their sphincters are more relaxed, leading to less noisy flatulence.
text: The auditory pitch all depends on the tightness of the sphincter as well as the velocity of the gas being expelled.
