This image contains a spectrograph across the neck and larynx area. Spectrographs are eerie, ghostlike renditions of sound and are used clinically for investigations of human voice. Here you can see some coloured lines in and among the black stripes: these are bands of more concentrated sound energy and occur at predictable intervals on a pitch scale. The healthy human voice is a richly multilayered sound, and unique to the person based partly on physical considerations. I thought it would be interesting to layer the scientific measurement of voice, with an actual neck and oral cavity beneath it to create a visual rendition of the act of speaking, or I guess it would have to be humming, since mouth is closed!
