Application Summary AI generated

This standard specifies an objective method for measuring the prominence of impulsive sounds (e.g., construction impacts, gunshots) and adjusting the equivalent continuous A-weighted sound level (LAeq) to account for their annoyance. It is applied in environmental noise assessment, particularly for industrial sites, shooting ranges, and urban planning, where impulsive noise events require correction beyond standard steady-state noise metrics. The standard ensures consistent evaluation of noise pollution that includes short-duration, high-energy sounds.
