Abstract
Noise industry is a major cause of fatigue, irritation, decreased productivity and occupational accidents. Dangerous
to hear continuous exposure to 90dB or above. One of the main methods of noise control is to place sound absorbing
barriers (made of jute) between the source and the subject. The goal of this study is to study the acoustic properties of
biodegradable and easily disposable natural fiber jute and compound it for noise reduction in household appliances,
automotive and architectural applications. The effect of the type of fabric and the number of layers of different non
woven fabrics have been studied in indigenously made tools. Nonwoven fabrics show higher noise reduction than woven
fabrics. The fabric is assessed by placing the fabric 8 cm from the sound source and the receiver decibel meter (R) 16 cm
on the same side. It can be observed that randomly laid jute samples reduce the maximum noise among all the samples
tested. As the number of layers of nonwoven fabric increases, the noise reduction through the sample increases initially
but after most it remains almost unchanged.
