Sound absorbers including porous materials are used widely for noise control. The most widely exploited and acknowledged absorption mechanism in porous materials is viscous friction due to relative motion between solid and fluid. Acoustical performance of carpet made of wool by using a traditional compression technique has been investigated. The results are very interesting.
