Hot-wire Microphone and Audio-resonant Selection

Abstract

UNDER the heading “News and Views” on page 235 of NATURE for Aug. 13, reference is made to my recent paper to the Radio Society of Great Britain on the “Hot - wire Microphone and Audio - resonant Selection”, The writer of the note is, I fear, too optimistic with regard to the possible applications of my paper.

I think that his conclusion that there is no reason why more frequencies could not be selected in the wave bands at present employed for broadcasting misses the point.
