EVALUATION OF METHODS OF REDUCING COMMUNITY NOISE IMPACT AROUND SAN JOSE MUNICIPAL AIRPORT

A computer simulation of San Jose Municipal Airport was made of the airport noise impact on the surrounding communities. Alternate operational procedures, improved technology, and land use conversion were evaluated as methods of reducing noise impact in the airport application to other airport communities similar to San Jose. Two segment approaches and thrust cutbacks on takeoff were found to be very helpful in reducing community noise impact; however, these procedures cannot reduce the noise very near the airport. The introduction of sound absorption material (SAM) was found to reduce noise annoyance by over 25%, and the introduction of refan by over 60%. Replacing the present aircraft by DC-10's was found to reduce the noise problem to very small proportions, and the introduction of an advanced technology twin was found to essentially eliminate the noise problem.
