How to fart quietly
Release the fart slowly.
Rather than release the fart quickly, which will likely cause a loud fart noise, take your time and release the fart slowly. Do this by squeezing your abdominal muscles and taking long inhales and exhales as you release the fart.

Available options:
1). You may want to take shorter inhales and exhales to get the necessary pressure from your lungs. Place a hand on your belly to simulate a burp..
2). Avoid releasing a fart right before you are in the bathroom. Rub your upper abdomen to keep your abdominal muscles contracted..
3). Releasing the fart slowly should cut down on the noise it makes as it comes out of your butt. Or spread your buttcheeks as far as you can from each other to make a smooth, wavy fart that can sometimes have no scent at all..
4). If you exhale too loudly, you'll actually let out more fart sound. Use the effective excuse: " hey, man, that really hurt my stomach..
The answer is:
3).
