1. A method of detecting the health of a structure so as to determine structural collapse comprising:

  • (a) utilizing a Health of Burning Structures system having at least one of a Power Spectral Density Analysis, a Root Mean Square Analysis, a Signal Bandwidth Analysis, a Maximum Entropy Method Analysis, a Random Decrement Analysis, a Hilbert Transform, a Shock Response Spectrum, a Wavelet Transform Analysis and a Damping Estimation Analysis;

    (b) obtaining amplified digital data signal from at least one device;

    (c) conveying said data signal to a means for analyzing said data;

    (d) filtering and removing signal noise from said digital data signal using band stop filters;

    (e) obtaining a filtered signal;

    (f) locating frequencies having magnitudes greater than eight standard deviations above a mean frequency amplitude to remove said signal noise;

    (g) displaying said signal; and

    (h) storing said signal in a means for data storage.
