Abstract

The sea represents 70% of the earth's surface and the possible use of sound-absorbing materials with this origin is little investigated. The purpose of this article is to investigate the possible acoustic applications of a floating seaweed (Pelagic Sargassum) very common in the Caribbean area. The presence of these floating algae and their stranding on the coasts is constantly increasing due to climate change, and constitutes an economic and environmental problem. To mitigate these problem projects have been proposed for the collection of this algae, and research is underway for the use of these materials as natural resources within production cycles in various industrial sectors. This article investigates the potential use of dried Pelagic Sargassum for the production of sound-absorbing panels that combine good acoustic properties and attractive design, and presents an experimental investigation aimed at modelling the acoustic propagation inside the material with variable apparent density.
