LPS-3 Loopset
The LPS-3 Loopset has been developed for hearing aid users to allow them to use mobile
phones. It is based on induction technology.
All hearing aids have support for induction loop, that is, they have a little tele-coil inside.
This coil can capture the signal supplied to the loop. Standard hearing aids have two
operation modes: (1) the M-mode for normal microphone use and (2) the T-mode for
tele-coil.
