History
In 1934, aviator Wiley Post incorporated earphones and a throat mic into the design of the world’s first pressure suit to explore the limits of high-altitude, long-distance flight. During World War II German Luftwaffe pilots and panzer crews used the first throat microphones. Soon after, they were adopted by American air forces, (USAF with the T-20 and T-30 and the UAF with the Mark II). Later, Soviet pilots relied on LA-3 and LA-5 models.
Starting in the 1970s, researchers explored the use of throat microphones in speech therapy, especially to relieve stuttering.
Of course, throat microphones have still maintained their presence in the military, SWAT, law enforcement, and emergency services. Newer single-transducer designs are available that make the throat microphone much more comfortable to wear than earlier units and also better balance transmission quality. Additionally, this next generation of throat microphones provides varying outputs and frequency responses to accommodate a wide variety of professional communication devices such as digital and analog portable radios and TETRA & P25 systems.
In 2009 Mad Catz released the first "throat microphone" for game consoles as a Call of Duty: Modern Warfare 2-branded Xbox 360 accessory. It should be noted that these devices (usually marketed as "throat communicators") are not true throat microphones, since they have no contact microphone (which is designed for sound waves traveling through solid objects) and simply incorporate a throat-mounted, open-air microphone. These therefore will still pick up background noise from and cannot transmit whispers.
In 2012, Astra Radio Communications released its T24 "throat microphone" which is the first throat microphone compatible with the new digital two way radios in United States.
Several throat microphones now exist for mobile phones, including iPhone.

Famous quotes containing the word history:
“You that would judge me do not judge alone
This book or that, come to this hallowed place
Where my friends’ portraits hang and look thereon;
Ireland’s history in their lineaments trace;
Think where man’s glory most begins and ends
And say my glory was I had such friends.”
—William Butler Yeats (1865–1939)
“History is not what you thought. It is what you can remember. All other history defeats itself.
In Beverly Hills ... they don’t throw their garbage away. They make it into television shows.
Idealism is the despot of thought, just as politics is the despot of will.”
—Mikhail Bakunin (1814–1876)
“It is true that this man was nothing but an elemental force in motion, directed and rendered more effective by extreme cunning and by a relentless tactical clairvoyance .... Hitler was history in its purest form.”
—Albert Camus (1913–1960)
