Electric Acoustic Stimulation

If you have trouble hearing high-pitched sounds, discover how an Electric Acoustic Stimulation (EAS) system could give you the joys of sound.

What is EAS

What is EAS?

Are certain sounds easier to hear than others? Do people always sound as if they're mumbling? Do you feel that your hearing aids are just not good enough?

If this sounds familiar, you may be missing out on hearing high-pitched sounds. When you cannot hear high-pitched sounds, you have a type of hearing loss known as high-frequency hearing loss. This type of hearing loss is common in both children and adults.

EAS is the combination of two technologies: cochlear implant technology for high-pitched sounds, and hearing aid technology for low-pitched sounds. By using two different technologies in one device, you can hear the full range of sounds, making it much easier to chat with friends, enjoy music, and communicate in everyday life.

Low-Pitched Sounds—Hearing Aid Technology

Low Pitch Sounds 1 2 3
  1. 1Sounds are detected by the microphones of the audio processor.
  2. 2Low-pitched sounds are made louder and sent through the earmold to the ear.
  3. 3These sounds are processed by the cochlea and sent to the brain.

High-Pitched Sounds—Cochlear Implant Technology

High Pitch Sounds 1 2 3
  1. 1Sounds are detected by the microphones of the audio processor.
  2. 2High-pitched sounds are sent to the implant as electrical signals.
  3. 3These sounds are processed by the cochlea and sent to the brain.
Benefits of EAS

More Than Just Hearing

EAS is proven to give you better hearing. And better hearing has many more benefits for your lifestyle, including:

  • Easier to socialise with friends
  • Improved relationship with family members
  • Better hearing in noisy settings, like restaurants
  • Easier listening on the phone
EAS System

The Perfect Match

Your EAS system consists of two parts: the implant and the audio processor. The audio processor is worn on the outside of your head, sitting comfortably on your ear. It contains the microphones that pick up the sounds around you, and then sends these sounds to your implant and the earmold in your ear. You’ll wear your audio processor all day every day, except when you’re asleep.
The implant is surgically placed just under your skin, and works with your audio processor to let you hear sounds as naturally as possible. This part of the system will be with you for many years to come, so you should keep the future in mind when choosing your implant.

And with the help of our apps, you can make hearing with your EAS system even simpler and more convenient.

The Next Steps

What can you expect next? Here’s an outline of the process of receiving a cochlear implant.

1

Assessment

 

First, you’ll undergo routine assessments to ensure you’re a candidate for EAS, and if there are any additional factors to consider. Your clinical team will walk you and your family through the specifics of what to expect in the following steps.

2

Implantation

 

The surgical procedure is straightforward and usually lasts between 1–2 hours under either general or local anaesthesia. Recipients are usually back on their feet the next day. Your hospital stay may last one or more days, depending on your individual needs and what’s typical in your area.

3

Activation

 

About four weeks after implantation, you’ll have your first fitting. This “activation day” is when your audiologist will turn on your audio processor for the first time and you’ll hear your first new sounds. The audio settings of your processor will be adjusted to fit your hearing preferences.

4

Rehabilitation

 

After activation, it’s important to follow up with a rehabilitation programme so that you can adapt to hearing with your EAS system. Rehabilitation is essential to make the most of your implant. It can be done together with speech-language professionals and at-home listening exercises.
