New research further clarifies how different areas of the brain process different parts of the creation and expression of a thought. Here's the summary article: https://www.sciencedaily.com/releases/2022/01/220112093712.htm , and the Nature Communications research paper here: https://www.nature.com/articles/s41467-021-27725-3 . I found this bit of discovery especially interesting: "First of all, the oscillations called theta (4-8Hz), which correspond to the average rhythm of syllable elocution. Then the gamma frequencies (25-35Hz), observed in the areas of the brain where speech sounds are formed. Thirdly, beta waves (12-18Hz) related to the cognitively more efficient regions solicited, for example to anticipate and predict the evolution of a conversation. Finally, the high frequencies (80-150Hz) that are observed when a person speaks out"

New research into the early noise making in the Animal Kingdom points to insects, Author Michael Habib tells us that animal noise making began during the Cambrian period between 541 and 485.4 million years ago, but was restricted to "the skittering of arthropod feet across sand or the faint grinding of a cephalopod breaking a shell" while "the terrestrial realm remained essentially silent. 200 million years would pass before insects started making noise in open air: the katydid, 250 million years ago. He also points to the evolution of the larynx 300 million years ago, without specifically naming the lungfish, as we have cited researchers naming in this chapter (see Midgley and Allen 2002 and Fitch 2010 on page 29 of this chapter for sources). Here's link to the article in Scientific American: https://www.scientificamerican.com/article/fossils-reveal-when-animals-started-making-noise/

Tim Parsons, former Purdue Lighting Professor, shares his story about how he used the prosody of the Mandarin language to make decisions about how to make edits in a video project for the new Baiyun Guangzhou International Airport for its premiere in China: "I think that you would get a kick out of how a lighting designer resolved the Guangzhou video audio. I found a collection of traditional Chinese folk music recorded by Yo Yo Ma. I researched each piece and assigned them to different fly thru. For example the international returns concourse piece was about how it was nice to travel but was wonderful to finally be home. As for the Mandarin voice-over...there was a Chinese engineer in my building. I recorded him doing the voice-over in Mandarin and English having broken up the text into each fly-thru. I rough edited with English in my right ear and Mandarin in my left ear. I fine tuned listening to similarities in inflection, pause and emphasis. The engineer upon hearing the final version was impressed with the music selection but stunned as to how a non Mandarin speaker could have edited it so precisely down to what was being discussed. I never told him how I did it. I still can't believe it worked out so well. Tim" An exceptional example of the music of prosody. Thanks Tim!
