Nucleus® Smart App: Hearing Tracker


The Nucleus® 7 Sound Processor constantly monitors the listening environment and is able to determine when speech is present. The charts on the 'Time in Speech' screen track the time spent in a speaking environment. If you use a streaming accessory (e.g. a compatible iPhone), that time is also calculated and added to the total 'Time in Speech'.

The time spent in a listening environment correlates to progress in your hearing journey. The 'Time in Speech' goal is different for everybody and depends on age, family and work situations and where you are in your journey. A good way to get started is to track your 'Time in Speech' for a week or so, then set your goal a little higher and see if you can improve.

Tips within the Nucleus Smart App can help you to increase your 'Time in Speech'.


'Coil Offs' are the number of times the Nucleus 7 Sound Processor coil was disconnected from the cochlear implant in a given day. This number reflects all instances when the coil was deliberately removed (e.g. while changing clothes or while taking a shower) and also instances when the coil was disconnected unintentionally (i.e. accidently knocked off). A 'Coil Off' may also be recorded if there is a problem with your coil cable.

The number of 'Coil Offs' varies for everybody, as it depends on your lifestyle. It is a good idea to establish your own baseline. You could use the average number of 'Coil Offs' every week to get an understanding of what is normal for you or your child. Alternatively, you could make a note of the number of 'Coil Offs' on a day when you are confident that there were no or minimal number of unintentional 'Coil Offs'. You can use this baseline to determine if the number of 'Coil Offs' you are seeing is higher than usual.

Tips within the Nucleus Smart App can help you with suggestions to reduce the number of 'Coil Offs' you experience.


The connection between your Nucleus 7 Sound Processor and your compatible Apple device may have been lost, so insufficient data was collected during this period.

To prevent this from happening in the future, ensure that both your compatible iPhone or iPod touch and sound processor are switched on, Bluetooth® is enabled and that your compatible Apple device is close by (at least once in the morning and once at night).

Please note that for data to be collected, the Nucleus Smart App must be running, but not necessarily be active in the foreground.


No. You just need to ensure that the compatible Apple device and Nucleus 7 Sound Processor are both switched on, are close to each other regularly (at least once in the morning and once at night), and that Bluetooth is enabled and the Nucleus Smart App is running on the compatible Apple device.


No. Your privacy is important to us. The Nucleus 7 Sound Processor monitors the environment and detects speech, but does not record audio.


Cochlear does not store your Hearing Tracker data. It is only stored on your compatible iPhone or iPod touch.
