Acoustic
When articulating some sounds, conditions arise that lead to the appearance of so-called antiresonances . The antiresonances of the vocal tract, as the name implies, have an effect on the oscillations of the sound source that is opposite to the effect of resonances . They sharply weaken the amplitude of the components with frequencies close to the natural frequency of antiresonance, which is expressed in the formation of deep (to zero) minima in the transfer function of the speech tract or in the strong suppression of close resonant frequencies.
Antiresonance in mechanics
Under certain conditions, for a system of two bodies connected by a spring to each other and with a fixed support, the body to which the exciting force is applied remains stationary. This phenomenon is called antiresonance in mechanics. The phenomenon of antiresonance in mechanics is used in dynamic vibration dampers.
