Noise can affect in a good sleep and cause the disturbance in listening, and cause discomfort and other non- auditory effects. There are many ways to scale back this unwanted Sound. Now a day Egg cartons are very popular for the purpose of sound absorbers because they are very cheap, simple to put in and add to that they are simply available on the market. However, there's some experiment conducted to demonstrate the negative effects of Egg cartons as a sound absorption material. To beat it flaws Enhance Egg Cartons are used that accommodates textile waste and chopped rice straw paper. Apart from Egg Carton, Gypsum Board is a decent Sound riveting material that has comparatively positive impact for each Low and High Frequency. Aside from these two materials Sound diffuser is also becoming popular for Sound absorption and sound scattering. The aim of this paper is to point out that Enhanced Egg cartons and Gypsum Board can be used for acoustical treatment purpose in an enclosed space and Sound diffuser is extremely helpful to scale back echo and reverberation because it scattered sound waves. Previous Researches are being the overview in this paper to support the reason for using this material as good Noise reducing material and thus, this material will act as a useful and economical material in soundproof construction technique. Key Words: Egg carton, low cost, textile material, rice straw, Gypsum Board, Wooden plywood, sound absorption, sound diffuser, Frequency, Reverberation. 1.INTRODUCTION With the enhancement in Technology, our day to day life becomes quite easier, but this also led to some side-effects, such as pollution. Pollution can be understood as the sum of the components that impart a negative effect on our environment, and noise is considered as one of those components. Noise or more specifically noise pollution has become a major problem, as it can affect the activities of a large number of people. Medical studies show that Noise pollution can cause very harmful effects on human body it might increase the stress level and can also cause hypertension. A Medical study shows that if some is in high noise frequency range for longer period of time they may temporally or permanently loss hearing. Apart from that noise can cause sleeping disturbance, tinnitus and other harmful effect on body. To resolve this Noise pollution problem certain technique is being developed which are called as Noise controlling technique. Now, what is Noise Controlling? It is a set of technique to minimize noise by stopping or reducing noise form it source of origin, either by hindering sound to propagate using noise barriers or similar strategies, or by the use of ear protection from noise by using earmuffs or earplugs. For the purpose Noise Barriers, tons of materials are available, and egg cartons are considered to one cheapest of them. Egg cartons have long been considered by the general public to provide good sound insulation and absorption. They have three main positive points, which make them popular as acoustic material; they are inexpensive, easy to install and easily available. However, acoustics experts have shown that egg cartons are poor sound insulators and absorbers, backed up by laboratory tests, such as those done by Quintero Antonio. Thus, egg cartons should not be used if good acoustic quality rooms as expected. The acoustic performance of egg cartons has long been questioned. In most studies, it is found that Egg cartons are neither good sound insulators nor good sound absorbers. The sound insulation property of egg cartons is very low, so it should not be considered a sound insulator at all. Apart from Egg Cartons Rock wool, glass wool and mineral wool are widely used to provide desired sound and thermal insulation inside the building. However, these materials can cause various health related issues such as lung diseases and skin irritations and usage of these materials are banned in many countries. This growing awareness of the environment and health led researchers and the industrialists to develop a new and alternative cost effective solution. This environment and health conscious aspect draw researcher attention to the use of the Recycled material. The sound absorption property of waste and industrial byproducts had been studied by many researchers and some effective byproduct like tea residue, cassava residue, coir, rice straw and textile waste are coming up which give good
