Creating and sharing knowledge for telecommunications

Project: Hybrid Log Shielding

Acronym: HLS
Main Objective: The effects of noise on human health are well known, and clearly constitute a significant impact on the exposed population. Noise mitigation measures are available, and are often used along important roads, usually in the form of noise barriers. Moreover, society in general has progressively awaken for the exposure dangers to electromagnetic waves associated with, for example, mobile communications. Hybrid solutions that combine the protection of these two types of waves are not available, but will surely be an asset to society, and a commitment to consider in the near future.
In this project, it is intended to develop a number of innovative and highly sustainable barriers made of circular section timber of low industrial processing, based on the sonic crystal concept solutions designed to minimize the effects of traffic noise and / or exposure to electromagnetic radiation. It is intended that the developed solutions may constitute an effective barrier, either from the acoustic point of view or from the radiation point of view. They may be implemented only thinking about one of these components, but may also form a hybrid solution that ensures simultaneously the two components. It is also envisaged, in the case of acoustic barriers, to enhance the radiowave propagation transparency of such structures to mitigate the shadow areas, e.g. as in public roads. Given the innovative and even disruptive character of the proposed solution typology, it is considered that the project could generate a product of great practical interest, allowing economically valorization of an existing natural and renewable resource in the Central Region of Portugal. Thus, a very positive economic impact is expected, and the possibility of internationalization for European markets, particularly in countries where regulatory requirements and social awareness with regard to noise and electromagnetic radiation are more intense, is considered as very viable.
