Material used for acoustic textiles

Abstract

This chapter discusses about textile materials used for noise/sound absorption applications. Various types of raw materials used for manufacturing of acoustic materials such as, natural and synthetic fibres, along with recycled materials were covered. Different types of porous absorbing materials as well as panel absorbing materials were discussed. Acoustic properties of materials coated, sprayed or embedded with chemicals and fillers were also covered. Use of nanomaterials for acoustic applications particularly for absorbing low and medium frequencies were discussed. Some of the recent trends in developing hybrid type of acoustic absorbers where acoustic property was effectively controlled with the help of active as well as passive absorbers were also covered. Furthermore, new types of panel absorbers were also discussed.
