Acoustic Source Localiztion

For technical derivations of the acoustic source localization techniques outlined below, please refer to the PDF file attached.

Techniques for measuring the position of an acoustic source

Technique 1: Triangulation of the acoustic source with use of three sensors

Triangulation

Techinque 2: Minimization of Error Function

Location of the acoustic source is found by identifying the set of coordinates (x_0 and y_0) that minimize the error function Surface of Error Function

Log Plot of Error Function

Technique 3: Interpolation of known time delays between sensor pairs

Location of sample impact points; sensors are located at each corner impact locations

Surface plot of the difference in arrival time of leading Lamb wave between one sensor and another Time Delay Surface

Contour plot of lines of constant time delay

Isolines Time Delay
