Sound insulation for buildings under Part 150

Abstract

Part 150 of the Federal Aviation Regulations provides a mechanism for the operators of noise-impacted airports to develop comprehensive programs to limit or reduce noise effects, including noncompatible land uses. In developing these programs, the airport operator is required to consult both with the users of the airport and with local, state, and federal agencies having land-use planning authority. These groups then examine various alternative operational and land-use actions and devise a plan suited to local conditions. One option for decreasing noncompatible uses is sound insulation of buildings in impacted areas. In fact, Part 150 itself cites several combinations of uses and aircraft sound levels that require specified noise level reductions to be considered compatible. Obviously sound insulation can be installed as a part of the original building design; however, in many cases, additional insulation may be required. Oftentimes, this supplemental insulation is eligible for funding under the federally funded Airport Improvement Program. Of the 31 noise compatibility programs that have been submitted to date, 20 have included planned increases in sound insulation in one or more structures.
