Externet Posted April 16, 2017 Posted April 16, 2017 Is the method to generate sound in cetaceans analog to a human vibrating lips as in playing a trumpet ? Are the pressure waves in the melon organ direct result from 'lips' closed and opened obturing/releasing air many times per second ? It does imply some air exiting past their 'lips' while vocalizing; is that right ? The melon or spermaceti organs are to enhance volume by resonance, as a guitar body does, is that right ? Is the animal sound emission omnidirectional and its echo reception directional ?
