Jacob Kirkegaard, sonic artist extraordinaire, hailed for his work inspired by natural phenomena and scientific explorations is making music out of the sounds your ears make. Originally trained at the Academy of Media Arts in Cologne, Germany, the Denmark-born artist has numerous critically acclaimed exhibitions and permanent installations under his belt. Starting with recordings of underground geysers or caving of glaciers or even empty rooms in Chernobyl, Kirkegaard has created musical pieces combining the natural acoustics with layers of artistic magic.
As part of his recent residency as the first Sound Artist at St. John’s College (University of Oxford), Kirkegaard used spontaneous otoacoustic emissions as inspiration for a composition he named Eustachia—for 20 voices. While at Oxford, Kirkegaard recorded spontaneous otoacoustic emissions (emissions recordable without any external stimulation) from individuals at the university. Each of these recordings would have contained at least one, but perhaps more than one, spontaneous emission at different frequencies. Kirkegaard analyzed, filtered, and then interpreted groups of these recordings to create a piece first performed by Aarhus Pigerkor in August 2017.
Apparently, the creative process was easy but the composer was worried that the human voice would not be able to hold a set of notes for a substantial period of time. Each performer was given a tuning device to use as a point of reference during the performance. It worked beautifully. You can hear an excerpt and even watch a brief video of Aarhus Pigerkor rehearsing.
It is rather sobering to think that the ear holds the notes of a spontaneous emission for decades when trained performers fear to do the same for a minute or two. Cheers for our amazing ears.
“Huh?” is used in at least 31 languages around the world! A version of the word can be found in nearly every language on Earth (Dingemanse et al, 2013). This research concluded that all languages studied included a word similar, in both sound and function, to the English “huh?” Regardless of language, the word is…
If you have a dog or cat, you’ve probably seen their ears moving toward an interesting or startling sound. For professional equestrians, watching the ears of their horse allows them to gauge their shifting attention. Humans still have these same muscles, and even more interesting is their relationship to our brain and how we pay attention. …
Tai Chi is not just for increasing balance; it may also help improve cognitive performance. In a recent randomized controlled trial, study participants who practiced a form of Tai Chi twice a week for six months improved their scores on the Montreal Cognitive Assessment (MoCA) when compared to a control group (Fuzhong et al, 2023)….
