The operation of large wind turbine generators in the United States and Europe has, in some instances, resulted in adverse community reactions to the associated low-frequency noise. The resulting frequency range for the perception studies reported is

Predicting the audibility of a sound over ambient noise is an important step to assess its impact on observers. One anticipated need for such predictions is the desire to operate aerial vehicles in urban surroundings close to the public. The increase

NASA Langley Research Center has conducted three groups of studies on human response to sonic booms: laboratory, "inhome," and field. The laboratory studies were designed to: (1) quantify loudness and annoyance response to a wide range of shaped soni
