Abstract
Acoustic signals are received, selectively filtered, and digitally processed, e.g., by digitizing an amplitude, the peak of an echo, or the transit time, and the digital data are stored in a memory whose storage cells are associated with particular frequencies. Other acoustical signals are similarly processed but compared with the reference data to obtain a spectral representation of differences or ratios.
