MED-EL Announces Launch of ASM 2.0 Features for SONNET and SONNET EAS Audio Processors


New Features Incorporate Microphone Directionality and Wind Noise Reduction.

May 10, 2017 – (DURHAM, NC) – MED-EL USA announced today the availability of Automatic Sound Management (ASM) 2.0 features for the SONNET and SONNET EAS audio processors. ASM 2.0 actively adapts to changing listening environments, including background noise and wind, and is FDA approved for all SONNET users.

Key features of ASM 2.0 include:

  • Microphone Directionality, which reduces the impact of background noise by utilizing both microphones already built into SONNET audio processors. Natural and Adaptive Directionality are two new features that minimize distracting environmental sounds for better understanding, especially in noisy environments; 100% of SONNET users showed improvement in speech understanding in noise when directionality features were enabled.[1]

Natural Directionality mimics the way the pinna (outer ear) works for people with normal hearing, by slightly enhancing sounds from the front and at higher frequencies. When using Natural Directionality, SONNET listeners showed up to 54% improvement in speech understanding in noisy conditions, with sounds from all around the listener still audible.1SONNET users with ASM 2.0 also have the option of the Adaptive Directionality feature, which is more aggressive in identifying and minimizing background sounds. Adaptive Directionality can identify and lessen specific noise sources coming from the sides and behind the listener, and can track those noises as they move in the environment, providing a significant enhancement to sounds coming from the front of the listener. When using Adaptive Directionality in challenging background noise environments, SONNET listeners showed up to 109% improvement in speech understanding.1

  • Wind Noise Reduction, which minimizes wind noise when wind turbulence is detected across the microphones. The level of wind noise reduction can be programmed for specific situations and preferences. When Wind Noise Reduction is enabled at the ‘mild’ level in combination with Natural Directionality, listeners can anticipate up to 36% improvement in speech understanding in windy conditions. A ‘strong’ setting is also available if more wind noise reduction is desired.1
  • Automatic Volume Control, which continuously monitors the environment and seamlessly adjusts volume levels between noisy and quiet environments to ensure every sound is heard clearly and comfortably. While recipients can still control the volume level independently by using their FineTuner remote control, Automatic Volume Control reduces the need for the listener to make adjustments during the day. Many recipients find they only rarely need to adjust the level, making listening feel more natural and worry-free.

“Sound is not static. It moves all around us, as do background noises that can disrupt the hearing experience,” said Raymond Gamble, CEO & President of MED-EL North America. “People with normal hearing tune out extraneous noises without giving it much thought. But people with hearing loss tend to struggle in noisy environments. The new ASM 2.0 features allow SONNET users to experience sound in an even more natural way. These seemingly small changes can add up to effortlessly improved hearing for our recipients, and we’re thrilled to be able to offer this new technology.”

People who already use SONNET processors can easily have ASM 2.0 enabled at their next regular visit to the CI clinic. The entry-level setting will combine Wind Noise Reduction with Natural Directionality. MED-EL cochlear implant centers are currently receiving the information needed to activate ASM 2.0 features. CI Audiologist training on the features is available either directly from the center’s MED-EL representative, online, and/or through regional training workshops currently being scheduled.

About MED-EL

Austria-based MED-EL Medical Electronics is a leading provider of hearing implant systems with 29 subsidiaries worldwide. The family-owned business is one of the pioneers in the industry. The two Austrian scientists Ingeborg and Erwin Hochmair developed the world’s first microelectronic-multichannel cochlear implant, now considered the modern cochlear implant, which was implanted in 1977. The cochlear implant was and remains the first replacement of a human sense, the sense of hearing. In 1990 the Hochmairs laid the foundation for the successful growth of the company when they hired their first employees. To date, the company has grown to more than 1,700 employees around the world.

MED-EL offers the widest range of implantable solutions worldwide to treat various degrees of hearing loss, including cochlear and middle ear implant systems, and the EAS (combined Electric Acoustic Stimulation) hearing implant system. In July 2016, MED-EL acquired the technology for a novel non-surgical bone conduction system from the Swedish medical device company Otorix, further expanding the number of people who can benefit from innovative hearing technology and reinforcing MED-EL’s mission to overcome hearing loss as a barrier to communication. People in over 100 countries enjoy the gift of hearing with the help of a product from MED-EL. Visit or the MED-EL Expo Page on AudiologyOnline to learn more.
