Dr. Salt is a researcher with the Department of Otolaryngology at Washington University in St Louis. He gained a Ph.D. in cochlear physiology at the University of Birmingham, UK in 1977 and performed post-doctoral studies at the University of Southampton, UK and the National Institute of Environmental Health Sciences, Research Triangle Park, NC, USA before taking an academic position at Washington University in 1984. He is currently a Professor of Otolaryngology.
His research has been funded by NIH for over 20 years and has focused on how inner ear function depends on the fluids of the ear that bathe the sensory cells. For years, he and his group have been using very low frequency sounds as a tool to manipulate the inner ear while measurements were taken. These studies showed that infrasound at frequencies as low as 1 Hz had a major influence the function of the inner ear, even at levels that would not be heard. This work confirms that the inaudible, infrasound component of wind turbine noise stimulates the ear at levels that are not heard.
