Development of acoustical absorptive technical textiles and their characteristics

Abstract

Acoustic absorption property is an important aspect of any material meant for acoustical environment which decides the human comfort Noise control and its principle play a critical role in creating an acoustical pleasing environment An important feature of any acoustic textile material is the absorption of sound which makes the human being comfortable Hence acoustic absorption can be viewed as controlling the intensity of sound or noise in a living place using different types of acoustic absorbing materials newlineReflection refraction absorption diffraction and interference are the critical factors to assess the performance of textile materials with respect to acoustic absorption The influence of absorptive characteristics of textile materials has a significant result in acoustical comfort Noise is an unpleasing sound and unfortunately most of the equipments in industries high speed vehicles and other facilities produce noise The noise system consists of three elements such as noise source noise path and noise receiver These three are the essential factors to be considered for the noise control one of the methods is by providing absorbers along with the noise path, resulting in human comfort newline
