SONOGRAPHY

The art of SOUNDSCAPE notation. It includes customary methods of notation such as the SPECTROGRAM and the graphic LEVEL RECORDER, but beyond these it also attempts to register the geographic distribution of sound events. Various mapping techniques are employed to create, for instance, the ISOBEL contour map and the ACOUSTIC PROFILE.

Sonography is an alternative term for ultrasound scanning (see ULTRASONIC).
