why does it make a bad sound when you pass gas?!


Question:

Answers:
The word "FART" can stand for: Frequency Actuated Rectal Tremor.

The sound of a fart is caused by the vibrations of the anal opening. The sound of your fart depends on the speed of the fart leaving your body and the tightness of the sphincter muscles of your anus.

cause it's coming out of a tight hole

Because your body is trying to push out alot of gas through a tiny hole.

From Wikipedia <chuckle> :

Mechanism of action

The noises commonly associated with flatulence are caused by the vibration of the anal opening. The sound varies depending on the tightness of the sphincter muscle and velocity of the gas being propelled, as well as other factors such as moisture and body fat. The pitch of the flatulence outburst can also be affected by the anal embouchure.

Flatus is brought to the anus in the same peristalsis method as feces, causing a similar feeling of urgency and discomfort. Nerve endings in the rectum learn to distinguish between flatus and feces, although loose stool can confuse these nerves, and sometimes results in accidental defecation.
