Acoustic Characterization of Impulsive Underwater Noise Present in Port Facilities: Practical Case in the Port of Cartagena

This study reveals significant spatial variations in underwater noise levels within the Port of Cartagena, identifying key sources of impulsive noise that could impact marine biodiversity. Researchers used a smart digital hydrophone mounted on a vessel to record sound pressure levels between 10 and 200 kHz, coupled with GPS data to create a GIS map of spatiotemporal noise distribution. The findings highlight the need for targeted management strategies to mitigate impulsive noise pollution in port environments, serving as a foundation for future studies on its ecological effects.
