Velocity‐sensitive phonograph cartridges can be very useful for vibration measurements on light structures where accelerometers present too much mass loading. This paper describes how stereo phonocartridges may be calibrated and used to measure in‐plane (horizontal) and also transverse (vertical) motion. Topics of discussion include frequency response, dynamic range, proper mounting methods, and calculation of the effect of the stylus impedance on vibration of beams and plates. Data from measurements on several different structures is included.
