: Most human farts have a peak frequency between 200 Hz and 300 Hz .
A fart sound effect (SFX) is an acoustic event produced by the vibration of the anal opening as pressurized gas is expelled from the rectum . The specific tone, pitch, and texture of the sound are determined by a combination of gas volume, exit velocity, and the tension of the sphincter muscle. Acoustic Characteristics Fart sound effect
: Variations in volume can range from a whisper (20 dB) to loud, "thunderous" blasts that may exceed conversational noise levels (60–70+ dB) depending on gas buildup and force. : Most human farts have a peak frequency
Fart sounds generally occupy the lower frequency spectrum but possess complex harmonic structures: Acoustic Characteristics : Variations in volume can range
: They often feature odd harmonics (e.g., 750 Hz and 1250 Hz), similar to the acoustic properties of a brass instrument like a trombone.
: While dominated by low rumbles, farts also generate broadband frequency spectra that extend into the ultrasonic range (above 16 kHz).
