For years, upgrading a hearing aid meant better battery life or Bluetooth. But according to experts at Mayo Clinic, the latest devices are doing something far more revolutionary: using artificial intelligence to think for themselves.
“Ultimately, the goal of these technological advances is to remove some of the responsibility and heavy lifting from the brain and ears, hearing aids can now pinpoint what the sound is, where it’s coming from and its relative importance.” explains Courtney C. Luffler, Au.D., an audiologist at Mayo Clinic in Jacksonville, Florida
The most impactful advance in the field is the use of deep neural networks—a type of AI that mimics how the human brain learns. Modern hearing aids are programmed with millions of sound samples. The tiny computer chip inside constantly monitors the wearer’s environment, instantly separating speech from background noise and making automatic adjustments for each ear.
“No hearing aids have true AI that learns the patient’s behaviors yet. However, AI is changing the processing strategy within the device.” Dr. Luffler clarifies
Newer devices also utilize enhanced binaural signal processing, allowing a pair of hearing aids to function independently yet simultaneously to isolate noise. This evolution changes how wearers perceive space.
Historically, hearing aids assumed that whatever you were looking at was what you wanted to hear. But if you are a rideshare driver needing to hear passengers in the back seat, traditional directionality falls short. “New hearing aids focus on detecting sounds from all around the wearer,” says Dr. Luffler. “The 360 program enables you to hear what someone is saying to your back.”
Despite these innovations, Dr. Luffler emphasizes that technology is only half the story. Adjusting to a new hearing aid can take two to three weeks, or longer for those upgrading from older models.
“Hearing aids are not miracle devices, and they don’t give back normal hearing,” she cautions. “We just try to set up our patients for success.”
To that end, Mayo Clinic relies on real ear measurements to ensure devices amplify sound precisely for each patient. If red flags like dizziness arise, audiologists collaborate closely with specialists.
“Our priority is making sure that our patients are healthy,” says Dr. Luffler. “We make whatever adjustments necessary to fit the patient’s lifestyle—because the best hearing aid is the one that the patient is going to wear.”
