This paper presents an optimization study of sustainable sound-absorbing panels made of jute fiber, developed for two different applications: the first, with a thickness of 40 mm, is optimized for wall mounting, while the second consists of a 20 mm thick panel designed for suspended ceiling installations with an air cavity. The design process began with an experimental study of the acoustic performance of loose jute fibers, with the objective of achieving Class A performance (αw ≥ 0.90) according to ISO 11654. This study was conducted in collaboration with the Danish company Hubbub ApS.

Abstract
This paper presents an optimization study of sustainable sound-absorbing panels made of jute fiber, developed for two different applications: the first, with a thickness of 40 mm, is optimized for wall mounting, while the second consists of a 20 mm thick panel designed for suspended ceiling installations with an air cavity. The design process began with an experimental study of the acoustic performance of loose jute fibers, with the objective of achieving Class A performance (αw ≥ 0.90) according to ISO 11654.
