Abstract:
Noise control materials are used in passive noise control and are sensitive to different noise sources. The noise reduction characteristics of a material are studied using impedance tube. In this paper we studied the accuracy of the modified impedance tube. The sound absorption coefficient were calculated using two materials namely cotton felt and Polyurethane Foam in two different impedance tubes, existing impedance tube and an modified impedance tube for a frequency range of 80Hz to 1600Hz. Sound absorption coefficient of both the materials were measured. The difference in valus of the existing tube and modified tube were studied and error in the reading of the modified impedance tube has been calculated.
