Webinar: Rating Level, for Industrial and Environmental Noise Assessments
The Rating Level Lr is used to assess the level of disturbance of industrial or environmental noise. Its evaluation begins with a measurement of the averaged sound pressure level LAeq. Penalties are applied for tonal and impulsive characteristics dependent on the time of the day.
The webinar explains how to objectively identify the relevant impulses and tones using both survey grade and engineering grade methods including FFT tonal assessment by the reference method, and how to calculate the applicable penalties.
