Installation of an exhibition at the Museum of Musical Instruments

UNC audiology and speech-language pathology professors Don Finan and Deanna Meinke collaborated on a project for the Musical Instrument Museum, which has a collection of 6,500 instruments, including those by a host of legendary artists , including Elvis Presley and John Lennon.

They recently installed a mock-up of the stand-alone Properties of Sound exhibit, which features an “instrumented” mannequin, known as “Jolene.”

“A custom-designed and built Jolene will be at the heart of the exhibit, allowing museum patrons to gauge the loudness at which they typically listen to music,” Finan said. “The sound level (in decibels) will be displayed on a large computer screen with a dynamic display of the associated safe listening time per day based on that specific sound level.”

The final exhibit will be built and installed in early September, and the exhibit will go live at that time. The grand opening of the museum for the exhibition will take place in early 2018.

Impression of the newly designed custom Jolene ear. The printer filament (raw material for printing) used is very strong, but retains flexibility (similar to human outer ear cartilage). The ear was designed to precisely fit the headphones used at the Musical Instrument Museum while having acoustic properties that mimic real human ears.
