In this paper we present the operation results of a portable computer-based measurement equipment conceived to perform non-destructive testing of suspicious termite infestations. Its signal processing module is based in the Spectral Kurtosis (SK), whose pattern allows the targeting of alarms and activity signals. The estimator of the SK is proven previously using a set of synthetics. SK enhances the non-Gaussian behavior of termite signals, giving rise to a sensitivity improvement. As a complementary tool, wavelets confirm non-Gaussian behavior of termite emissions by keeping the approximation of the register, with less entropy.
