Phonak have sent me (I couldn't find it on internet) the water resistant rating for the Phonak Naida S (not core, core is less). It is IP54 which Google says dust proof and splash proof only.
I have found when a single drop of water hits the microphones it causes all sorts of problems, it must be the naida's achilles heel
Thanks for the replies, i've changed the weather protectors many times, still the same really. Its just annoying when phonak advertise the Naida v sp as water resistant on the main website(picture of the aid covered in water) and they also state it is suitable to be used outdoors, during heavy exercise(sweating) I cant see how this can be true because if you get the slightest drop of water on the top 2 weather protectors the sound becomes distorted/ whistling etc etc whilst they are still wet.
Just ordered some ear gears for my naida sp hearing aids- i'm expecting terrible feedback with them on, haven't got them yet. Like what other members have already stated, I get feedback also by waving my hand close to my ears.
The joys of being deaf hey!
On the plus side I get a damn good peacefull nights sleep with my HA's out in this hot weather with the windows wide open! I can't hear any road traffic at all!
There are plus sides to being deaf!
You may not get feedback as I have a friend with SP Naida and she is able to use the ear gears.
Most of my lost is in the low frequencies which mean you get more feedback anyway.
Good Luck, hope they work.
Just curious, what size did you get?
Just something I thought of. Do you have the FM battery draws on yours? Everyone who I know that has nhs Naida aids do not have the fully closed battery draws. This means your aids are not classed as water resistant. This maybe just my hospital that does this tho.
