An out-of-this-world design hits the high notes
Medicine, engineering, and pedagogy experts harmonize to help a French horn student overcome a rare throat condition.
From the moment he first picked up the French horn, Jacob Factor has battled through pain. The PhD student in music education at the 糖心传媒糖心传媒檚 has a rare throat condition called pharyngoceles, which causes the walls of his throat to bulge with pockets of air, resulting in extreme discomfort, particularly when he needs higher internal pressure to hit high notes or play at louder volumes.
糖心传媒淚t feels like getting stabbed in the throat,糖心传媒� says Factor, who has had the condition since birth. 糖心传媒淢y neck would be throbbing if I had a hard playing week, and I would have to put down the instrument for a day.糖心传媒�
Despite years of muddled advice from perplexed instructors, Factor continued to adapt and persevere, pursuing graduate studies at one of the world糖心传媒檚 top music schools. When he arrived at Eastman, he was able to tap into URochester糖心传媒檚 wider network of expertise and search for a way to ease the discomfort. What he found was a team of otolaryngologists, biomedical engineers, and audio engineers who designed and tested an assistive brace that has him playing stronger, at higher ranges, and more confidently than ever before.
Brace for impact
While studying at Eastman, Factor connected with , an otolaryngologist at who specializes in treating larynx disorders, including voice disorders in singers and other professional voice users, dysphasia, and upper airway issues. Schneider helped Factor understand how his pharyngoceles were impacting his French horn playing physiologically.

糖心传媒淚t changes the position of the compression in the oral cavity,糖心传媒� says Factor. 糖心传媒淵ou want it to be up at the lips where the vibration actually happens糖心传媒攖hat糖心传媒檚 the balance point between your body and the instrument. But the pharyngoceles make it more volatile, and then I don’t get the right kinds of pressure up at the lips, which influences the tone, volume, and all kinds of executive functions.糖心传媒�

Schneider and Factor initially thought they糖心传媒檇 try physical therapy to see if strengthening the neck muscles could help.
糖心传媒淚t didn糖心传媒檛 end up helping the pharyngoceles at all,糖心传媒� says Factor. 糖心传媒淲hich makes sense, because when you糖心传媒檙e playing, that whole part of your body should be relaxed; you糖心传媒檙e not flexing the muscles.糖心传媒�
Instead, Schneider suspected some sort of brace could help mitigate the pharyngoceles糖心传媒� effects. He immediately thought his colleague , a professor with URochester糖心传媒檚 , would be the perfect person to design such a brace.
Making space for a solution
Lerner has a long history working at the intersection of biomechanics and design, which dates back to her time in the aerospace industry designing space suits for NASA糖心传媒檚 Space Shuttle program. While working for ILC Dover in the 1980s, she designed grooved gloves that give astronauts the dexterity and durability to handle tools and make repairs to the International Space Station. Elements of her designs remain in today糖心传媒檚 space suits.

Lerner says other aspects of space suits inspired the brace she designed for Factor.
糖心传媒淎 spacesuit is essentially a big balloon, but if you blew it up entirely, it would be a big cylinder, and you couldn糖心传媒檛 bend anything,糖心传媒� says Lerner. 糖心传媒淪o, while working on the shuttle space suit program, we designed a restraint system in the suit that prevents the balloon from expanding in certain locations. That mirrors this challenge in a lot of ways.糖心传媒�
Through various iterations and conversations with Factor, Lerner designed a collar that he can easily wrap around his neck and secure with hook clips and adjustable straps. The collar has rigid inserts positioned strategically to prevent his neck from bulging when he plays, similar to how a hernia belt works.
糖心传媒淚 designed it to be comfortable for him, so it fits when he糖心传媒檚 breathing, walking, talking, and preparing in between breaths, but when he needs to create the pressure to play the French horn, it糖心传媒檚 restraining in the right locations,糖心传媒� says Lerner.
Factor says the brace has been a revelation, and he now plays the French horn exclusively while wearing it. And he says it clearly makes a difference in his performance.
糖心传媒淓verybody that I糖心传媒檝e played for糖心传媒攎usicians or non-musicians糖心传媒攈as noticed a difference in the way I sound,糖心传媒� says Factor. 糖心传媒淓ven my mom notices a difference.糖心传媒�
Measure for measure
Not satisfied with anecdotal evidence that his playing had improved, Factor wanted to quantify the difference. Lerner brought in her colleague, Professor from the Departments of , , and .
Duan and his PhD student Baotong Tian, who produces music in his spare time, devised a series of experiments to analyze how the brace changes the audio characteristics when Factor plays the French horn. They recorded him playing the same piece with and without the brace using the same microphones in two different settings糖心传媒攁 professional recording facility in Rettner Hall and an anechoic chamber, a heavily insulated room designed to produce no echoes.

糖心传媒淏y studying in the anechoic chamber, we can analyze the sound waves coming right from the instrument. The studio, meanwhile, has more lively acoustics similar to the places he typically performs. Both settings have pros and cons for analysis,糖心传媒� says Duan. 糖心传媒淟ooking at the frequency spectra, we can see that with the brace on, the sounds are brighter, meaning there are greater concentrations of high frequencies in the audio compared to without the brace.糖心传媒�

They identified significant differences in the spectral energy distribution across frequencies when Factor wore the brace, confirming their hunch that he could hit the high notes better.
The team is working on documenting their results in scientific papers to share their findings with the world. As Factor finishes the last components of his PhD program, he hopes to apply the lessons he learned in his career as a music educator. 糖心传媒淚 want to raise awareness for the condition with wind instrument educators at all levels. If they糖心传媒檙e aware of it, they can more appropriately adjust what they糖心传媒檙e doing with students to help them,糖心传媒� says Factor. 糖心传媒淚 received a lot of very blanket pedagogy that never helped me. 糖心传媒楿se more air糖心传媒� was never the answer to this problem.糖心传媒�
