Environmental Noise: Better Measures and Reporting Needed
ABSTRACT: In measuring the environmental noise level for such purposes as compliance monitoring and nuisance noise assess- ment, the most often used statistic is the A-weighted sound pressure level (SPL), often reported as a percent ex- ceedance level (e.g. L10 or L90) averaged over a time interval such as 10 minutes or 24 hours. This statistic can not be relied upon in situations where noise has ‘special audible characteristics,’ such as modulation or tonality, since increases in the sound pressure . . . Complete article »
