1. A vibratory gyroscopes, comprising:

  • a vibratory element;

    means for inducing a mode of vibration into said vibratory element, said inducing means including an acoustic signal source provided at a location spaced from said vibratory element;

    means for detecting strain in said vibratory element;

    processing means for generating, in response to a change in strain detected in said vibratory element, a signal indicative of a rate of rotation about an axis of said vibratory element corresponding to a rotation imparted to said vibratory element subsequent to an inducing of said vibration; and

    dampening means for reducing to zero said change in strain, said dampening means including an acoustic signal source.
