Noise Attenuation Using Vegetal Supported Barriers and Buffers Zones in Obio/Akpor, Port Harcourt, N

Noise pollution is an undesirable sound that damages the quality of our environment, making the environment in which we live and work uninhabitable. In the wake of increased human activity, which has resulted in and accelerated noise levels, the situation is no different in the Port Harcourt metropolis. As a result of this circumstance, various steps to reduce noise levels employing vegetative cover supported barriers have been adopted. As a result, it is necessary to investigate the attenuation of environmental noise exposure employing vegetative cover and its supporting barriers. Environmental research design was employed and a total of twelve samples were collected for each barrier types with the aid of the digital noise meter (EXTECH instrumentdigital sound meter with RS232) to measure noise level in decibels (dBA). Findings revealedthat areas with bare surfaces across its property corridor witnessed did not decrease noiselevels at destination while surface with vegetation such as lawns within its propertyboundary corridor witnessed reduced noise levels of destination. As a result, it is proposed that vegetal surface walls be encouraged to promote the construction of noise barrier walls across the urban space in order to reduce urban noise and make urban regions/areas more habitable.
