Study Shows Benefits of Cochlear Implant Processor

Cochlear Americas announced today the results of a new study published in Otology & Neurotology, which demonstrates the benefit of the dual-microphone technology in the Cochlear Nucleus 5 CP810 Sound Processor. The study illustrates how the Nucleus 5 sound processor provides significantly better speech recognition in quiet and in noise when compared with the performance of the Cochlear Nucleus® Freedom™ processor.

“Cochlear implants are highly successful devices for many adults who have severe to profound hearing loss; however, most recipients continue to experience difficulty understanding speech in the presence of competing noise,” said Jace Wolfe , Ph.D., CCC-A, Hearts for Hearing, Oklahoma City, lead study investigator. “Results from this study indicate that the Nucleus 5 sound processor provided a significant improvement in speech recognition relative to the performance with the previous generation sound processor.”

The Nucleus 5 sound processor contains two microphones, which are precisely calibrated and phase matched to +/-1 dB tolerance to ensure accuracy and consistency. With two microphones the Nucleus 5 provides a directional mode called “SmartSound® zoom” technology, which significantly lessens competing background noises, as well as enhancements in the signal processing chip to enhance speech recognition in quiet and noise.

“This study demonstrates our commitment to continually improving the experience of our recipients,” said Christine Menapace, MA, CCC-A, Vice President of Clinical, Training and Education at Cochlear. “Every new generation of the Nucleus Sound Processor has been backwards-compatible, enabling our cochlear implant users to upgrade to the latest technological improvements, such as the dual-microphone ‘SmartSound®zoom’ technology.”
