"As much as possible" - raises the question - 'possible with what?"
possible with current hardware? current software? with how much effort?
Remember - readily achievable and undue burden are still in effect. So the
"lowest possible level" language may be ok because it automatically becomes
"lowest possible level that is readily achievable" for 255
"lowest possible level that isn't an undue burden for the government to
purchase" for 508
Actually, if we just leave it as lowest possible - then the limits
This is testable by companies but not by anyone else.
Makes it possible to comply but hard to externally verify without company
providing rationale and/or info.

The original standard is problematic because the "lowest possible level" is
extremely subjective which leaves procurement officials with no way to judge
conformance based on vendor provided information. Without reference to a
metric or some measurable way to evaluate the level of interference, the
standard doesn't accomplish much. Unfortunately, the suggested re-wording
doesn't address the problem -- "reduced as much as possible" is no more
measurable than "lowest possible level". Is there not some metric used to
measure interference or is it just a subjective rating?

At the TC SC yesterday the following provision was discussed. Consumers
want to keep the original 508 text at 2.3-B. Alternative language has been
proposed - see below - as some people have expressed concern about the
"lowest possible level" wording. We do not want to weaken the provision,
which we believe the new alternative text does. Please review the two
versions below and give me your feedback ASAP

1194.23(i) Interference with Hearing Device
This text is unchanged from original 508 text. It is at 2.3-B of the EWG
July 6 Draft.
Interference to hearing technologies (including hearing aids, cochlear
implants, and assistive listening devices) must be reduced to the lowest
possible level that allows a user of hearing technologies to utilize the
Note: Text may need to be reviewed again; "lowest possible level" is
problematic. Possible alternative text:
Potential sources of interference to hearing technologies (including hearing
aids, cochlear implants, and assistive listening devices) must be reduced as
much as possible to provide a more compatible environment for a user of
hearing technologies to utilize the telecommunications product.
