Methods of signal processing to determine the sound speed as a function of frequency in a system to record sound of a geological formation.To determine the length of the geological formation as a function of frequency in a system to record acoustic geological formations, and,To determine the acoustic velocity and the dispersion of frequency of a geological formation. The report shows a technique of signal processing for recording acoustic devices.The method involves receiving a set of acoustic signals and convert those signals received in its representation of the field of frequ00b3u00eancia.The values of the domain representation of frequ00b3u00eancia along frequ00b3u00eancias constants are correlated to produce a correlation matrix.Eigenvetores and eigenvalores the correlation matrix are determined, and the eigenvetores corresponding to the signals of interest are removed to create a subspace.Then, a series of test vectors, the vectors of test are a series of values of slowness estimated, are applied to the vector subspace.If the test vector map or can be represented by the subspace, then the slowness estimated achieved in the test vector maps the system noise and is not the correct value of the formation.If, however, the test vector does not map the subspace, so the slow place in test vector is closer to the actual formation slowness.
