Acoustic noise reduction within the ASW support communications modules of the tactical support center (ASCOMM/TSC)
Abstract
The ASW Support Communications (ASCOMM) portion of the Tactical Support Center (TSC) provides communication terminals during ASW aircraft missions for voice, teletype, and data transmissions in Uhf, hf, and FLTSATCOM modes, both clear and encrypted. ASCOMM equipment consists of crypto equipment, remote controls, modems, patch panels, communications console, teletypes, teleprinters, reperforators, tape punches, and air conditioners. A sound survey at Naval Air Facility, Sigonella, Sicily, resulted in the NELC task reported here to reduce the ASCOMM noise level at all mobile ASCOMM/TSCs worldwide. NELC determined the sources and the extent of the noise problem, identified the system constraints, and designed and built equipment to minimize the noise problem with minimum interference to system operation. The equipment will be installed at NAF, Sigonella (the site which originally reported the problem) in July 1976, and before and after operational equal-level noise contours will be obtained.
