||Two main objectives of the study were: (1) To establish a threshold of acceptability for commercial aircraft sonic booms, (2) To investigate and develop the technology to provide simulation to any community noise problem. Seven Community Noise Simulation Systems were designed and fabricated, and simulated sonic booms were introduced, via these systems, into the homes of twelve subject families. Acceptance, interference, and annoyance response data were measured. Three boom levels and two frequency schedules were studied. It was concluded that for establishing a design/certification sonic boom threshold of acceptability for advanced supersonic transports, a level of 87 dB should be considered for indoor living with not more than fifteen daily boom exposures (no nighttime booms). It was also concluded that the simulation developed can be used to establish standards involving traffic noise, noise from airports, construction noise, and effects of industrial noise on surrounding communities.
