The issue of an updated noise guideline for wind farms in South Australia represents the third (public) attempt at the Environment Protection Authority (EPA) to address wind turbine noise and unfortunately still contains significant errors and omissions as to to fundamental requirements with respect to the protection of the amenity of residents in proximity to wind farms. Despite complaints from residents and documentation in relation to such complaints, the EPA have not established appropriate criteria to protect the acoustic amenity . . .More »
Investigation of the unpleasantness of infrasound combined with audio sound using psychoacoustic scaling methods
ABSTRACT— At many immission sites, human exposure to infrasound (f < 20 Hz) is usually accompanied by sound in the audio-frequency range (audio sound, 20 Hz ≤ f < 20 kHz). This gives rise to the question of whether the interaction between infrasound and audio sound affects the quality of auditory perception. Psychoacoustic experiments were performed within the framework of the EARS 2 project of the European Metrology Programme for Innovation and Research (EMPIR). Recent results in this project had already shown that . . .More »
