Starkey’s Cetera technology makes the hearing aid “invisible” to the brain. Cetera removes the barrier between sound and the brain’s ability to process signals. The Cetera technology is based on an innovative new algorithm- the complex mathematical formula that drives a hearing aid. Cetera’s algorithm can match the exact characteristics of the wearer’s ear. This customization removes the barrier that most hearing aids erect between the incoming sound waves and the data sent to the brain for processing.
