DI-HFAC-81982, DATA ITEM DESCRIPTION (DID): INSPECTION OF SHIPBOARD NOISE CONTROL CONSTRUCTIONS AND RECOMMENDATIONS REPORT (13-APR-2015)
DI-HFAC-81982, DATA ITEM DESCRIPTION (DID): INSPECTION OF SHIPBOARD NOISE CONTROL CONSTRUCTIONS AND RECOMMENDATIONS REPORT (13-APR-2015)., The Inspection of Shipboard Noise Control Constructions and Recommendations Report documents the results of the following surveys of noise control constructions to ensure they are properly installed in accordance with requirements defined in the contract specifications: 1. Acoustic, thermal, and fire control insulation systems and hull damping systems; 2. Survey of installed resilient mounting systems; and 3. Other acoustic constructions identified in the ship specification(s), in DI-HFAC-81202, Noise Control Program Plan (NCPP), or in DI-HFAC-81278, Airborne Noise Analysis and Control Design History Booklet. a. This Data Item Description (DID) contains the format, content, and preparation instructions for that data generated under the work task described by the applicable portions of MIL-STD-1474 or the contract statement of work. b. This report aids the contracting activity in tracking the implementation of noise control designs and in evaluating the ability of actual constructions to achieve the sound attenuation characteristics defined in the contractor’s submittal of DI-HFAC-81202 and DI-HFAC-81278. c. This report aids the Government in deciding whether to accept the state of construction as presented, or to authorize corrective measures be undertaken by the contractor to produce constructions that are in compliance with standards referenced in the ship specification.
