Annoyance caused by amplitude modulation of wind turbine noise
ABSTRACT: A listening test has been performed to investigate the relationship between human annoyance and the amplitude modulation of wind turbine noise. To obtain sound samples for the listening test, sound from a 1.5 MW wind turbine in Korea was recorded. The strength of the amplitude modulation of the sound samples was defined in terms of the modulation depth spectrum, which was approximated by assuming that the sound samples are sinusoidally amplitude-modulated. The stimuli for the listening tests were created . . . Complete article »

Experimental study on rating scale for annoyance due to wind turbine noise
ABSTRACT: Wind turbine noise referred to as “swishing sound” causes annoyance due to the amplitude modulation of the aerodynamic noise from the blades. For that reason, many studies for rating scale realizing annoyance from the noise have been examined, but show little coherence with change of noise level. In the present study, an appropriate index for describing the annoyance tendency is suggested with jury test and correlation analysis. Twenty-eight stimuli created by numerical simulation for the test were provided and . . . Complete article »
