When nasal passages are being irritated, trigeminal afferent fibers bring impuls to a far yet not forgotten medulla oblongata. This implies that less than 1% of the droplets expelled travel at velocities greater than 10 m/s and almost 80% of the droplets travel at velocities slower than 5 m/s. A soldier underscored his conclusion with a sneeze. A typical sneeze has a maximum speed of 44 m/s. Every Time We Sneeze? Suppose the material emitted in the sneeze begins inside the nose at rest, 2.0cm away from the nostrils.

The maximum visible distance over which the sneeze plumes (or puffs) travelled was 0.6 m, the maximum sneeze velocity derived from these measured distances was 4.5 m/s. What happens if the error in the transmitted data is not corrected? Sneeze Trivia:How big is the power to sneeze? Until recently, the maximum visible distance over which the sneeze plumes (or puffs) travel was observed at 0.6 metres (2.0 ft), and the maximum sneeze velocity derived was 4.5 m/s (about 10 mph).
