    Mr. Reyff began his environmental studies career in 1989 as a meteorologist. He joined our firm in 1995 as an air quality and acoustical specialist, with a broad background in meteorology, air quality, and noise. Mr. Reyff has prepared both air quality and noise technical reports for Caltrans projects. In a particular research study funded by Caltrans, Mr. Reyff combined his expertise in meteorology and transportation noise to investigate long-range diffraction and reflection of noise from sound walls under varying meteorological conditions.
