Microbial Role in Cleaning Environmental Pollution

Noise pollution, unlike chemical pollutants, cannot be removed but must be mitigated through planning and engineering. Strategies include acoustic barriers, sound-absorbing building materials, and urban green buffers that reduce ambient noise levels. Vegetation and soil, which benefit from healthy microbial communities, play a passive but supportive role in noise reduction by softening surfaces and absorbing sound energy. A study on urban forest design showed that integrating dense vegetation can reduce noise by up to 10 dB in city environments (Fang & Ling, 2003).
