Hi there Dick,
I'm not overly aware of the process involved in programming hearing aids and
you have probably done this already, but I imagine it is worth making your
interest in birds known to the programmer (and the fact that bird calls
encompass a wider frequency range than human speech). The frequencies in human
speech go up to about 5kHz (some consonants like 's' and 'sh' and the harmonics
in some vowels), and hearing aids might be programmed primarily around human
speech , I'm not sure. I do know that cochlear implants are designed
specifically for human speech, so music and I imagine bird song can sound
distorted. I think. Anyway, just a suggestion to check this out - especially if
it is so costly.
How fantastic this little device has enhanced your birding experience in such a
fundamental way! I say go for hearing aids (I wish my dad would... :). Good
luck.
Cheers,
Arwen

Subject: Hearing Birds
Hi all
Since my teenage years I have always had problems hearing high pitched
sounds, particularly noticeable with Wrens, Finches , Thornbills etc .
It first came to light when I would be walking with my wife or others that
could hear, and I would say it is very quiet today and they would say no
there is heaps of birds around !
I have a very good eye for a bird so probably compensating for my lack of
hearing. I will often see birds that others have missed because they are not
calling.
I had a hearing test done 6 years ago which confirmed what I already knew,
but as the hearing aids that may correct this were $6000 a pair, I decided I
didn't need to hear extra birds that much.
Recently Hunter Hearing in conjunction with WIDEX Hearing Aids had a 30 day
free trial offer for their latest technology hearing aids, so I decided to
try them out.
My hearing had deteriorated even further since my last test so definitely
worth a try.
Frequencies over about 1.5 khz become harder for me to hear. My lower
frequency hearing is just under normal now also.
The hearing aids have a program to increase the clarity and decrease
background noise. I have been testing them out for the last week or so just
with normal situations of television , music etc and whilst I can now have
the volume lower, I am still no better off than before.
However, today , Lynn and I went for an early morning bird walk to see what
we could hear and I was absolutely blown away by the difference between them
in and out. Not only were all the birds louder , I could hear Wrens ,
Finches etc from a further distance than I could before. Some birds had a
level to their call that I didn't even know existed ! It was almost
deafening J. Sacred Kingfishers, Pheasant Coucals, Superb Fairy-wren,
Red-browed Finches , Silvereyes, Rufous and Golden Whistlers, Black-faced
Monarchs, Fan-tailed and Brush Cuckoo, Grey Fantail, Brown Quail, Lewins ,
Scarlet and Yellow-faced Honeyeaters , plus Rosellas , Galahs , Magpies ,
Crows etc
>From our front veranda I could hear Grey Shrike-thrush, Brush Cuckoo ,
Scarlet Honeyeater and Golden Whistler calling along the river which is at
least 300 metres away, that I couldn't hear without the aids.
The model is WIDEX Passion Clear 440 and they are now $10,000 a pair !!!
Are they worth it ..... I still have one week to decide.
I would be interested to hear of anyone else's experiences with hearing
aids.
Cheers
