Cochlear Nucleus Sound Processor reliability

The Nucleus Sound Processors are built to be very durable and the reliability ratings support this. Sound processor reliability is measured by the number of sound processors that are returned over a period of time compared to the sound processors sold over that same time period - Failed Component Return Rate or FCRR. These returns can be due to mechanical, electrical, moisture or damaged/unknown malfunctions. The lower the number, the better.

  • Nucleus 7 Sound Processor: 0.5% FCRR over 2 years 1,5
  • Nucleus Kanso Sound Processor: 0.3% FCRR over 2 years 1
