CRYSTAL-LUNG is a project aimed at developing an innovative solution to substantially reduce two environmental issues associated with port logistics activities: air pollution and noise levels. It employs a system based on so-called “sound crystal” technology to create a permeable acoustic barrier with the capacity to absorb atmospheric pollutants that are highly harmful to human health.
As it is based on “sound crystal” technology, the CRYSTAL-LUNG device provides a tool that enables noise reduction not from a general perspective, as a traditional barrier would, but through attenuation that can be “tuned” to target the most problematic noise frequencies in the area of application.
In this way, the CRYSTAL-LUNG project proposes the development of a new product with a dual function related to the control of both air pollution and noise. On the one hand, the device will enable the absorption of air pollutants—specifically particulate matter such as PM10, PM2.5 and Black Carbon (PM1). On the other hand, it will allow for the targeted control of noise pollution through a bespoke (“ad hoc”) design addressing noise sources from port logistics activities. To achieve this, a pilot barrier will be implemented to validate a shielding system capable of addressing both environmental challenges with a single device. The solution therefore consists of an acoustic screen which, thanks to its wind-permeable design, acquires particle-capturing properties and thus also functions as a barrier for reducing air pollution.
