Noise Mitigation in Buildings Using Sound Absorbing Materials

Noise, generally defined as undesirable sound, is characterized in terms of the pressure of the sound wave. The improvement on the human quality of life and the continuous growth in population in developing and developed societies, have exacerbated the environmental and financial issues. Some of these problems are noise and the different types of human an industrial wastes. Many natural products have been recently developed and tested for acoustic applications. Sound-absorbing materials absorb most of the sound energy striking them and reflect very little. Therefore, sound-absorbing materials have been found to be very useful for the control of room noise. In this study, sound absorption technology as an effective noise reduction technology buildings using sustainable acoustic absorbers, will be discussed
