MIL-PRF-87819A, PERFORMANCE SPECIFICATION: HEADSET-MICROPHONE, (HEARING PROTECTIVE TYPE, HIGH AND MODERATE AMBIENT NOISE LEVELS), GENERAL SPECIFICATION FOR (30-JAN-1997) [SUPERSEDING MIL-H-87819A]

MIL-PRF-87819A, PERFORMANCE SPECIFICATION: HEADSET-MICROPHONE, (HEARING PROTECTIVE TYPE, HIGH AND MODERATE AMBIENT NOISE LEVELS), GENERAL SPECIFICATION FOR (30-JAN-1997) [SUPERSEDING MIL-H-87819A]., This specification covers the requirements for headset-microphone with rigid headband. These parts meet established requirements for communications equipment used to protect against hazardous noise exposure and are approved for use in certain high and moderate ambient noise level applications (see 6.1). The term headset is to be used interchangeably for headset-microphone and is used when referring to any of the articles covered in this specification. Products delivered under this specification are intended for use in high and moderate ambient noise level environments. These environments are areas where the ambient noise levels are between 105 dB SPL and 125 dB SPL (i.e., ground crew and aircrew). All hearing-protective requirements in this document and its slash sheets (intelligibility, noise-attenuation, sensitivity) were developed by Air Force agency (Air Force Research Laboratory (AFRL) 711th HPW/RHCB (Battlespace Acoustics) Wright-Patterson AFB OH 45433] and intended for products used by Air Force personnel, in cooperation with guidelines established by the United States Air Force Office of the Surgeon General. These field-reparable parts are repaired as specified in the Air Force Technical Order 12R2-2AIC-222CL- 1, which is available from the Air Force Custodian upon request. Products are expected to be effectively used for a period not less than 4 years, including authorized maintenance and repair.
