A Purdue University researcher is combining two technologies – hearing aids and cochlear implants – to help improve speech understanding and sound quality for cochlear implant users.
King Chung, assistant professor of audiology, sets up for her next experiment in the Amplification and Communication Research Laboratory at Purdue University. She will evaluate how hearing-aid technologies can improve the efficiency of cochlear implants. Chungs current research shows that by applying the front-end processing capability of hearing aids to cochlear implants, cochlear implant users achieved better listening quality.

Research by King Chung, an assistant professor in audiology, and colleagues shows that by applying advanced hearing aid technologies, such as preprocessors, to cochlear implants, background noise can be reduced, speech understanding enhanced and sound quality improved for cochlear implant users. Chung collaborated with Fan-Gang Zeng, a professor at the University of California, and Susan Waltzman, a professor at New York University School of Medicine.
"The common goals of hearing aids and cochlear implants are to enhance users speech understanding and listening comfort, as well as improve the convenience of device use," says Chung, who studies issues related to hearing amplification and communication. "To achieve these goals, hearing aid and cochlear implant manufacturers have gone through different research and development paths."

Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.
Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...
The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
New research group at the University of Jena combines theory and experiment to demonstrate for the first time certain physical processes in a quantum vacuum
For most people, a vacuum is an empty space. Quantum physics, on the other hand, assumes that even in this lowest-energy state, particles and antiparticles...
