(…) The physical properties of the sounds produced by toothed whales are directly affected by the morphological characteristics of the air space in the head and by the sound-production mechanism (Aroyan et al. 1992). In order to understand how sounds are produced, and why there are such different acoustic characteristics between families, detailed information about the shape and volume of the air spaces is needed. In this paper, we describe a new experimental technique making it possible to obtain this information. (…)
