Post by NyrathThis is embarrassing. Back in the 1970s I had read lots and lots of science fiction stories where people wearing space suits talked to each other by touching helmets, using sound conduction.
(generally because either the radio was malfunctioning or for privacy).
But I cannot remember any (except for a one-liner in Robert Heinlein's Space Cadet, when Matt drives the space scooter to the space station). They say your memory is the first to go...
I'm trying to make a list of a few instances.
Can anybody remember any examples?
Thank you for your time.
Frederik Pohl, "Wings of the Lightning Land", Astonishing Stories, Nov. 1941:
But he had an idea. He motioned me to come closer and touch helmets. In that
way the vibrations would be transmitted directly from helmet to helmet. If we
shouted we could hear each other and compare notes.

Clyde Beck, "Collision Orbit", Planet Stories, Summer 1950:
Betty came in just after the sun lifted over the horizon. She wouldn't let me
get close enough to touch helmets so that I could explain. I gave up after a
few attempts and we just sat.

Ben Bova, "Impact" (excerpt from _The Peacekeepers_), Aboriginal Science Fiction, March-April 1988:
After several minutes Kelly tapped Jay’s shoulder. He leaned down to touch
helmets.
“Isn’t Moonbase in that direction?” She pointed roughly southwestward.

Theodore Sturgeon, "The Incubi of Parallel X", Planet Stories, Sept. 1951:
"Now here's the plan. We have no radio. I was able to weld in some thin plates
to my helmet — I should be able to hear in there. I don't think you two will be
able to unless you touch helmets. I won't be able to hear you but I can hear
outside sounds. So once we get in there, we're pretty much on our own. All I can
say is — keep together and don't go too far. Mind you, this is just a
preliminary recon patrol. Later we can go back in with more and better
equipment. Ready?"

R. F. Starzl, "The Power Satellite", Wonder Stories, June 1932:
Again Glyda’s helmet clinked against Waite’s.
“My father understood the message. He warned the police. But he may not have
told them everything.”
Waite, looked up into the lovely face, wistful, appealing. He motioned to her
to touch helmets again.
“Are you asking me what I shall do?”
There was no need for an answer. Her eyes said “yes.”
