| Researcher trying to pick up distant sounds and signals. |
Update: This seems to be equipment used to listen to distant sounds of incoming aircraft before the radar was made.
Old Hearing Aid
The title is a joke, I know it's not a hearing aid, but I think it is some sort of a device used to register faint distant sounds and signals. Even though, the build doesn't seem like it's able to have a very long reach.
I really don't have any information on this contraption, if you happen to know anything more about it, feel free to post it in the comments section and I'll edit the article accordingly.
