Hi,
I’m a paediatric audiologist with more than 10 years experience working with children. Is there a particular reason why you haven’t been offered a rechargeable option? Are batteries funded for children in your region?
Physical fit and comfort is really important as is tamperproofing for the devices. Have you tried dummy aids behind the child’s ears to see what fits well?
Is there any reason why you’ve chosen Phonak devices? Oticon also make paediatric hearing aids which could also be an option. Phonak devices (at least the non-rechargeable ones) can have their housings changed from fun colours to hair colours if needed. Oticon housings aren’t exchangeable in the same way. Fun colours are easier to spot when your child removes and/or hides the devices.
The 90 level of technology is unnecessary for a child of this age. Most of the advanced features are disabled by default because the brains of young children work very differently to those of adults and their behaviour is also very different in that they don’t look at the person they’re listening to as frequently as adults do: they need to hear speech from all directions.
I wouldn’t recommend going above the 50 level of technology for a pre-schooler this young in the Phonak Lumity product. By the time they need more advanced features at school (year 2+) you’re probably going to need to upgrade as children’s aids tend to last only 4 - 5 years before they become unreliable due to the greater wear and tear for children’s objects in general. You’re better off putting the cost difference into a Phonak Roger wireless microphone like Roger On which will expose your child to language more easily as it can send your voice directly to the hearing aids while the range of the inbuilt microphones in the aids isn’t more than 1 - 2.5 metres in quiet and less in noise.
If you’re considering Oticon hearing aids, I would only recommend the top tier of technology (there are only two) due to limited input dynamic range in the lower tier which will give you significantly poorer performance in the types of noisy environments that children are in every day than the Phonak product at all levels of technology.
I wish you all the best in your journey. Remember, consistent regular use of hearing aids at least 10 hours per day and constant language exposure is necessary for continued speech and language development.
