Abstract

In this paper we present an experiment which shows the possibilities of wavelets to detect transients produced by termites. Identification has been developed by means of analyzing the impulse response of three sensors undergoing natural excitations. De-noising by wavelets exhibits good performance up to SNR = -30 dB, in the presence of white Gaussian noise. The test can be extended to similar vibratory signals resulting from impulse responses.
