double protection (plug and muff) are properly fitted and worn. The hearing protection module, described in B-A.3.4 and B-A.4, permits selection of appropriate hearing protection based on user-selectable parameters, such as requirements document statements or the operational environment involved. B-A.2.2 Analysis of separate impulses. The ARUs from separate impulses should be analyzed separately and summed to arrive at the total dose. One large impulse with 400 ARUs is equivalent to four impulses, each with 100 ARUs, or 100 impulses each with four ARUs. B-A.3 Obtaining, installing, and using AHAAH. B-A.3.1 Obtaining AHAAH.

to a sound pressure level greater than 140 decibels during operations requiring the intentional detonation of ammunition item(s) with an operational shield. 2. DESCRIPTION OF TEST. A maximum credible incident is created with the operational shield. Sound level meters are used to measure sound pressure levels. 3. CRITERIA FOR PASSING TEST. The operational shield shall be considered acceptable if it can be determined from noise level readings that personnel will not be exposed to overpressures greater than 140 decibels. 4. INSTRUMENTATION. All instrumentation shall meet requirements of MIL-STD-1474. 5.
