I have worked as a clinician in hospitals and private practice in New
Zealand and England for 10 years. I saw this problem with a number of
clients, particularly those who were young and athletic, who played squash
or took part in other physical sport or activities.
The "moisture problem" occurred irrespective of brand or model of hearing
The solutions I found helpful were
1. dry aid kits, which I gave to all clients as a precautionary measure
2. "Super Seals" - which are like a condom for a hearing instrument - for
3. "water proof" hearing aids - for extreme problems
These days I work for a hearing instrument manufacturer. From that
perspective I encourage you to discuss the problems you client is
experiencing with the relevant manufacturer. It may be possible to "paint"
the components in the aid with an extra coat of protection lacquer and / or
silicon to further reduce the chances of corrosion.

I have a fireman wearing the Phonak Piconet 2 P2 with the same problem. He
even sweats excessively when he eats Mexican food and the aids "go out". We
did decide to try the dry and store. It works VERY well for him. I
wouldn't say it takes care of the problem 100%, but I haven't had to send
his aids in for repair since he began using it and before they were going in
once a month! Very interesting question about the design...since we are
working with the same manufacturer here.
Hope this helps,

>Greetings To All,
>>I have a patient who is experiencing more than expected moisture problems.
>He currently wears Phonak Sona P2 binaurally. He comes in every 1-2 weeks
>reporting that one of his aids is "out". After removing the programming
>cover, I suction the moisture out of the programming port and microphone
>and the aid comes to life. He uses his charged Super Dri-Aid kit nightly

>mornings his aids come out of the jar working very well, but by 6:00 PM,
>the devices are "down". This may be some habituation effect, but due to

>his moisture problems.
>>1. I only have a few patients who wear this model (although he seems to
>wear his devices every day as long as he can), and so I am curious to know
>if this is a model design problem, or whether this is an individual user
>>2. I told him that I would look into the price on a Dry and Store unit, but
>I would not want this patient to spend the money if he continues to have
>this problem. Has anyone seen good/remarkable results with the Dry and
>Store unit for patients with excessive moisture problems that do not seem
>to get the full benefits from an inexpensive Super Dri-Aid kit?
>>3. Does anyone have any further suggestions for me or for the patient? As
>I mentioned earlier, he is a preacher (presently interviewing for open
>positions) and so this intermittent problem is really something that this
>man can do without.
>>All responses are greatly appreciated.
>>Note: He and I have a running joke that with all the follow-up office
>visits that he has had over the last year, that I lose money everytime he

>sessions, but he is frustrated and concerned with this problem, especially
>if he moved out of my area.
