I would highly recommend that you stay away from anything in the
ReSound Tradition line.  It is NOT a true programmable in the sense
that it cannot be electronically adjusted in the audiologist's or
HA dispenser's office.  ReSound sends the device with a pre-packaged
circuit that the person fitting the aid "adjusts" with a screwdriver.
If your hearing changes beyond the limits of the pre-packaged settings,
you are looking at having to send it to ReSound for re-packaging which
willccost you a few hundred dollars per aid.  IMHO, I believe that
ReSound introduced this product for any fitter unwilling to purchase
programming equipment, or for those who simply cannot understand
electronic programming technology.  Again IMHO, ReSound introduced this
product to fill a niche in their product line, but for what you get, it
is too expensive.  Any other two channel, WDRC, non-programmable aid
would cost you less money.  If price is an issue, look into the ReSound
Encore products (electronically programmable technology, two channel,
WDRC, one memory, no remote control) which is only a hundred dollars more
than the Tradition products.  The Encore line of ReSound is probably my
most popular products, especially for persons over 70 years of age.

(And who says audiologists are dishonest....)

The "Clamp logic" that you describe is called attack and release
time.  The attack time is the time required for the aid to respond
to a loud enough sound to invoke the compression of the signal.  The
release time is the time required to return the compressed signal back
down.  With a long release time (300 ms or more), users sometimes
complain of missing words when the hearing aid cuts down.  New users
with low tolarance levels depend very heavily on fast attack and long
release times in order to use the aids properly.  When I say properly
I mean that their only other alternative is to turn the volume/gain
down and thus missing a lot more of the speech signal.

ReSound is set to introduce a digital product in Feb. 1998.  Heard
this from my ReSound Rep. this afternoon.

It's a great product, either in the Premium (two memory, remote control)
or Encore (one memory, no remote control) line.  The long-term
adjustability (is this a word?) and flexibility is worth the money
spent over traditional fixed matrix aids that run nearly half the cost.
For those with active social lives (attends meetings, social gatherings,
frequents restaurants) I recommend getting one of the Premium products.
For those with a quieter lifestyle, consider the Encore line, which is
quite a bit less expensive.

Good luck in your information gathering.....
