Samenvatting
The environs of the San Francisco international airport include a large number of residences and other examples of sensitive land use that are acoustically incompatible with California state requirements for the noise levels found near the airport. In this study, a sample of 12 residences and 2 schools in the area was examined. Retrofit designs were developed for each structure to reduce interior sound levels, using simultaneous indoor-outdoor sound level measurements and architectural acoustical analysis of the structures. Follow-up sound level measurements were conducted to confirm the original acoustical predictions for interior sound levels.
