Projektbeschreibung
Textilien für den Lärmschutz in Städten
Städte sind laut. Lärm ist einer der größten Belastungsfaktoren in modernen Städten. Eine chronische Belastung durch städtischen Lärm zählt zu den größten Gesundheitsrisiken für Stadtbewohnende. Glasfaser und andere Schallabsorber kommen zwar weithin zum Einsatz, sind jedoch zu teuer und unpraktisch, um tieffrequentem Schall, wie er in städtischen Umgebungen sozusagen als „Grundrauschen“ auftritt, beizukommen. Dazu zählen auch Geräusche durch den Verkehr und Hochspannungsmasten. Das durch die Marie-Skłodowska-Curie-Maßnahmen finanzierte Projekt TextMetamater wird eine neue Materialklasse entwickeln, die aus Textilgeweben bestehen wird. Daraus lassen sich durch verschiedene Textiltechnologien und verschiedenen Anordnungen unterschiedliche resonante Elemente formen, z. B. Hohlraumstrukturen, Brechungsindexstrukturen und Membranstrukturen. Damit bietet sich eine neue Möglichkeit, um das Lärmproblem zu lösen und die Lebensqualität in städtischen Umgebungen zu steigern.
Ziel
Owing to rapid urbanization, millions of people are suffering noise, especially the noise in a low-frequency regime (<500 Hz). Conventional acoustic absorbers (e.g. glass fiber and polyester fiber) have been applied to control the noise by absorbing incident acoustic energy. While the sound absorption in the low-frequency regime using such absorbers is impractical because their dimensions are usually comparable to the large wavelengths of low-frequency sound waves. In recent years, acoustic metamaterials have exhibited excellent low-frequency sound absorption performance. However, these metamaterials usually produce only one narrowband absorption peak. Furthermore, the practical application of most of the acoustic metamaterials is hindered due to the high-cost manufacturing techniques (i.e. 3D printing) and low production efficiency. This project proposes a new classification of metamaterials which is composed of textiles. The textile manufacturing techniques are highly efficient. Textile fabrics can form different resonant elements (e.g. cavity structure, gradient index structure and membrane structure) employing textile technologies and manifold assemblies. Moreover, the different textile resonant elements can combine together to fabricate integrated broadband low-frequency sound absorbers. The knowledge and technologies from acoustic and textile disciplines will be integrated to achieve the aim. One of the most important aims of this project is to develop the metamaterials made by textiles to overcome the shortcomings of currently known metamaterials. This project provides a new possibility to solve the noise problem to increase life quality of the public. Another essential objective is to acquire new knowledge and skills from the host to improve the career competencies and professional experience of the applicant. This objective and sharing the skills with the host will be fulfilled through two-way transfer approaches (e.g. training, presentations, etc.).
