The Stapleton Noise Insulation Program (SNIP) was initiated by the city and county of Denver, Colorado, to provide aircraft noise insulation modifications to owner-occupied homes within the 70-L sub dn (equivalent day-night sound level) contour and to schools and churches within the 65-L sub dn contour of Stapleton International Airport. SNIP is not a part of an FAA Part 150 study, and such a study has not been completed on this airport. The project area includes approximately 3,936 homes, 22 churches, and 8 schools. The primary data base for homes in the study area was acquired from assessor's records. A data base program was used to sort and arrange the homes into distinct categories from which representative samples were selected for a detailed engineering survey--a total of 52 homes. Twenty-six of these homes were selected and used for preconstruction sound insulation testing, and 24 were used for preconstruction air infiltration testing. Because the construction funds available for this program limited expenditures to $7,500.00 per home, recommended sound insulation modifications developed from results of the detailed engineering survey were given priority to achieve the maximum sound insulation for the least cost. Two sample homes were completed as a part of the design phase. Before-and-after A-weighted acoustical tests show a 90 to 17-dB improvement in exterior-to-interior noise reduction as a result of SNIP modifications.
