A method for adaptively generating an improved sonic energy signal for use in testing a physical attribute of a manufactured object with a sonic signal generator and a sonic measuring device, the sonic signal generator operable in a first and a second state of operation, the sonic signal generator generating sonic signals about the manufactured object, the sonic measuring device measuring the sonic signals generated by the sonic signal generating device, the method comprising:
- producing a first sonic energy signal with the sonic signal generating device operating in the first state of operation;
- determining when a favorable signal to noise ratio (SNR) is associated with the sonic energy signal;
- determining when a favorable signal to noise ratio (SNR) is not associated with the sonic energy signal, wherein a second state of operation is operable to produce sonic energy signal(s) within the manufactured object having an improved SNR;
- selectively, based on the output of the step of determining:
- deriving the second state of operation of the sonic generating device;
- and
- producing a second sonic energy signal with the sonic signal generating device operating in the second state of operation.
