摘要

Detection of at least one object causing a signal of interest. In one embodiment, a method of detecting at least one object causing a persistent non-random pressure wave comprises: providing a digital signal representation of the pressure wave that includes respective amplitudes of the signal, in at least two different frequencies, and providing a detection indication based on a measured similarity between the respective amplitudes over time.
