[78-L] Acoustic v. radio

[Elizabeth McLeod]

The carbon microphones of the twenties had a thin sound, with fair midrange,
comparatively little bass, and a noticeable hiss. Listening to a broadcast
originating from such a microphone on a regenerative receiver, thru
high-impedance metal-diaphragm headphones, was not too far removed from the
sound quality you'd get on a telphone. A horn speaker used the same type of
receiver element as the headphones, and introduced horn resonances to the
mix. 

Radio sound quality took a tremendous jump in the late twenties with the
introduction of the condenser microphone and the electro-dynamic field coil
cone speaker, both of which got rid of the tinny quality and made
reproduction far more lifelike than anything previously available.
