Re: Loop vs FM vs IF assistive listening systems.

Only one point of disagreement.  Loop systems are stronger and, if
good quality, the strongest and clearest of the 3 kinds of ALSs.
But MANY hearing impaired people, particularly older ones, do not
have t-switches in their aids or are not yet using aids.
Unfortunately most in-the ear aids have none.  Since loop systems
(at least those I've heard about or used) can only be used with
t-switches, that leaves a lot of people who need it unable to use
the ALS.

FM and IR can both be used with t-switches or with head phones or
ear phones as well as with a loop for the t-switch.  The FM is
stronger than the IR and doesn't have some of the other
disadvantages--line of sight, interferance by someone in the way or
poor location of the transmitter, etc, so I prefer it.
