In fact everybody on this planet farts.
In fact, the average person farts about 14 times in a day with an average volume of one-half liter of gas per day.
That is a lot of air. But each fart you release is not exactly the same.
As a matter of fact, some sneak under the radar pretty subtly, while others, well, you can hear those go off from the next room.
So why do your farts sound different?
And is there anything you can do to make a loud fart turn into a silent fart? Hmmmmm
In the first place, farts depend on a lot of variables, including what you eat, drink, and the movements of your bodies when gas escapes.
Here is what is going on;
As food is digested, gasses including carbon dioxide, methane and hydrogen build up within the intestines and seek their way out.
The intestines contract and move their contents including gas through peristalsis or the contractions that move waste through your digestive tract—towards your anus.
Small gas bubbles accumulate into larger gas bubbles en route to it exits, and when your body lets out those gases, that is your fart.
Get this straight.
Your fart sounds depend on the vibrations produced as the gas exits your anal canal.
Despite popular belief, your fart noises have no business to do with the flapping of your butt cheeks.
The sounds of farts are very much shaped by their expulsion velocity as well as the shape and size of the anal sphincter opening at the moment of passing.
One Doctor compares it to a musical instrument: the smaller the size of the exit point, the higher the pitch—and perhaps more squeaky it will be. And the larger the opening at the moment, the lower the sound.
“There are likely many factors that determine the size of the anus in general at that moment of a fart, including general resting tone of the anus and other behavioural factors,” says Dr. Rice.
“You can manipulate the sound of farts by relaxing and tightening the external anal sphincter and diaphragm to change pitch, volume and duration of sounds.”
Hahaha very interesting and that’s true.
That anal sphincter tightening is similar to what you’d do if you were trying to hold in poop, and since the opening would be tighter, that could lead to a squeakier, shorter fart.
And the expulsion velocity or how fast the air is exiting your body plays a role, too.
In fact If the air is coming out faster, your fart would be more likely to sound louder.
Plus, if swallowed air is triggering your fart as is the case in the majority of farts they tend to be louder (but less smelly.
If your fart is primarily driven by digestion and bacterial fermentation, it will tend to be smaller in volume and sound, but stinkier.
In most cases, whether your fart is loud, soft, squeaky, or sonorous, it is really nothing to worry about.
