This reminds me, these acoustic couplers may need some
periodic
maintenance, such as putting some talcum powder on the rubber pieces
that hold the telephone handset. Some time ago I read about this
being a good way to preserve the rubber weatherstripping around car
windows (e.g., the 1970s Fords that didn't have frames around the
windows), now, I wish that I'd done that years ago. However, I was
thinking that it would just wash off when it rained and didn't do it,
and replacement weather seals now appear impossible to find. Now
then, I suspect that the replacement parts for these acoustic couplers
would be even more difficult to locate.
In addition to the degeneration of the rubber, are they subject to carbon
granule clumping in the microphone?
