1. A vibrometer adapted for use as a hand-held device for measuring vibration at a surface of a vibrating object, comprising:

  • a plurality of vibration sensors each having a respective axis of measurement in one direction for detecting an amount of vibration in the direction of said respective axis of measurement and for generating respective output signals representative of the respective detected amount of vibration in said direction;

    mounting means, formed of a rigid body adapted to be hand held with a contact point on a surface of said rigid body in contact with said surface of said vibrating object, for fixedly supporting said plurality of vibration sensors in respective orientations so that the respective axes of measurement of said vibration sensors all intersect at said contact point on said surface of said rigid body, said contact point being at a center axis of said mounting means, said respective axes of measurement of said vibration sensors intersecting said center axis at respective angles that are all equal to each other; and

    calculation means for calculating, on the basis of said output signals generated by said vibration sensors, an amount of vibration, at a measurement point that is on said surface of said vibrating object and is in contact with said contact point on said surface of said rigid body, and in respective directions in at least two measurement axes which pass through said measurement point on said surface of said vibrating object.
