• Regarding the palatal flutter in snoring, experimental and theoretical studies are carried out for the flutter of a soft plate placed in a channel flow. The results show that (1) flutter occurs with an oscillation of travelling-wave mode beyond a critical flow velocity, (2) the channel walls act to promote flutter, whereas the hard plate attached in front of the soft plate acts to suppress flutter, although both of those effects are rather slight, and (3) flutter could be predicted theoretically by taking account of the mechanical damping of the plate. It is noted in the experiment that, once flutter occurs, the soft plate oscillates with large amplitude, and a hysteresis is observed, in which the flutter does not cease until the flow velocity is reduced to be much lower than the flutter velocity.
