A method for checking the calibration of the Brüel & Kjaer type 8000 mechanical impedance head.
A simple method for calibrating the acceleration and force transducers of the type 8000 mechanical impedance head is described. The accelerometer calibration is referred to the gravitational acceleration, g. The method is limited to frequencies below 500 Hz. The force gauge is calibrated in terms of the force which is registered when a known mass is accelerated sinusoidally at an acceleration which is known from the calibration of the accelerometer.
