Sound power level and spectrum of port sources for environmental noise mapping

Abstract

Ports are noisy areas that are often located near populated centers, leading to disturbances for citizens. Neglecting these issues can result in health problems and committees that can impede the natural development of port economic activity, which is growing rapidly. Attention to the sector has increased in recent years, but mainly with studies devoted to the general impact on the population. There is currently insufficient information available regarding the inputs required to conduct noise mapping and assess its effects. This is due to the high quantity and diversity of sources present in the port area. Basing on measurements conducted following established and standardized procedures, the present work reports a database of sound power levels, third-octave band spectra, average duration, and source height for various types of equipment, including reach stackers, dock tractors, front lifts, forklifts, transtainers on wheels, container cranes, mobile cranes, and dry load handling scrapers, during their movements and cargo handling activities. Acousticians are expected to benefit from this detailed input data for noise mapping and environmental acoustic impact assessments.
