A METHOD FOR ASCERTAINING THE OUTPUT THRUST POWER OF A JET TURBINE ENGING COMPRISING THE STEPS OF, SENSING THE OUTPUT SOUND NOISE OF THE THRUST POWER OUTPUT OF SAID ENGINE, CONVERTING SUCH SOUND NOISE TO A CORRESPONDING ELECTRICAL VOLTAGE SIGNAL, FILTERING SUCH SIGNAL TO OBTAIN AN OUTPUT SIGNAL CHARACTERIZED BY FREQUENCIES OF SUCH NOISE WHEREIN SAID OUTPUT SIGNAL VARIES IN INTENSITY IN A PREDETERMINED RELATIONSHIP WITH RESPECT TO OUTPUT THRUST POWER OF SAID ENGINE, AND MEASURING THE INTENSITY AND CHANGE OF INTENSITY OF SAID OUTPUT SIGNAL.
