The truth is you do have some control over it.
But did you know that the sounds your fart makes may be under your control to some degree?
The anal sphincter muscles control the opening size of the anus.
With effective sphincter muscle control, slow and silent releases can be managed.
The ability to control them is also a very useful social skill to have, Dr. Weiss explains.
For people with reduced sphincter tone, the release of a fart can become involuntary, he says.

Other factors that affect fart sounds include the resonance and vibration frequency generated when the fart leaves the body.

The anal sphincter is a ring-shaped band of muscle surrounding the anal opening.
You have internal and external anal sphincter muscles.
The internal sphincter is an involuntary muscle that is designed to remain shut.
