Engineering music to sound better with cochlear implants

26.02.2016

When hearing loss becomes so severe that hearing aids no longer help, a cochlear implant not only amplifies sounds but also lets people hear speech clearly.

Music is a different story.

"I've pretty much given up listening to music and being able to enjoy it," says Prudence Garcia-Renart, a musician who gave up playing the piano a few years ago.

"I've had the implant for 15 years now and it has done so much for me. Before I got the implant, I was working but I could not use a phone, I needed somebody to take notes for me at meetings, and I couldn't have conversations with more than one person. I can now use a phone, I recognize people's voices, I go to films, but music is awful."

Cochlear implants are designed to process speech, which is a much simpler auditory signal compared with music. People with severe hearing loss also have lost auditory neurons that transmit signals to the brain.

It's not possible to tweak the settings of the implant to compensate for the loss of auditory neurons, says Anil Lalwani, MD, director of the Columbia Cochlear Implant Program. "It's unrealistic to expect people with that kind of nerve loss to process the complexity of a symphony, even with an implant."

Instead, Dr. Lalwani and members of Columbia's Cochlear Implant Music Engineering Group are trying to reengineer and simplify music to be more enjoyable for listeners with cochlear implants. "You don't necessarily need the entire piece to enjoy the music," Dr. Lalwani says. "Even though a song may have very complex layers, you can sometimes just enjoy the vocals, or you can just enjoy the instruments."

Right now the group is testing different arrangements of musical compositions to learn which parts of the music are most important for listener enjoyment. "It's not the same for somebody who has normal hearing," Dr. Lalwani says, "and that's what we have to learn."

Down the road, Dr. Lalwani thinks software will be able to take an original piece of music and reconfigure it for listeners or give the listener the ability to engineer their own music.

"Our eventual goal, though, is to compose music for people with cochlear implants based on what we've learned," Dr. Lalwani says. "Original pieces of music that will possibly have less rhythmic instruments, less reverb, possibly more vocals--something that is actually designed for them."

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
