DEVELOPMENT OF EAR PROTECTOR, ELECTROACOUSTIC, MX-7307()/UIC.

Abstract

The report describes a program of design, construction, and testing of the Ear Protector, Electoacoustic, MX-7307()/UIC, a device intended for use in armored vehicles carrying electrically fired weapons and equipped with Intercommunication Set AN/VIC-1(). When the weapon trigger is depressed, the Electroacoustic Ear Protector introduces a pulsed tone into the intercommunication system which protectively conditions the ears of the crew members against the ensuing gun blast wave. Weapon ignition is delayed long enough (approximately 1/8 second) for the tone burst to cause a protective auditory reflex in crew members before the arrival of the gun blast wave. Two prototype units were designed and constructed. After testing and acceptance of these two units with some modifications sixteen final engineering models for service tests were constructed and tested. (Author)
