摘要：Sound control is an important aspect of our society. There are a bunch of Articles mentioning the badeffects of noise pollution on health and society. Thereby high level of importance is given to provide a good andeconomical acoustical environment in a building. Apart from that acoustic also helps to an array and enhances theartistry of the music. Therefore it is also an important issue to satisfy the customers of concert halls, recording studios,and other entertainment industries. Nowadays Egg cartons are becoming a successful material for sound absorbersbecause of its quality of being regularly accessible, easy to setup and having a cost next to nothing. But, their capabilityis being questioned. There are few experiments that elaborate egg cartons is bad at sound absorption. To overcome itsweakness certain types of improved egg cartons and Gypsum Boards are used. Aside from these two materials Sounddiffuser is use. The sole purpose is to demonstrate the acoustical performance of this combine mechanism of EnhancedEgg Carton, Gypsum Board and Sound Diffuser by observing it Sound absorption coefficient reading on differentfrequency range from 125 Hz to 4000 Hz.
