unrelated aside since you linked to such an interesting web page.
this 1940 vacuum tube hearing aid used a bone-conducting transducer scheme.[1] I was stuck thinking that was a fairly new concept (at least from the 80s) for military comms, and was intrigued by the use of such tech in the recent Google Glass.
It's cool to see that the idea was much older than I realized.
