Acoustic applications utilize thin porous materials for a variety of reasons, the primary one being to provide an acoustic resistance. This resistance dampens acoustic modes, allowing the designer to control their behavior. However, to achieve consistent resistive damping requires a level of precision manufacturing not found in common materials. SAATI of Italy produces a broad range of specialty woven meshes for acoustic applications that achieve this precision through a highly controlled weaving process. Some understanding of the weaving process is helpful in guiding a designer’s choice of materials.
