Night-time decibel hell: mapping noise exposure zones and individual annoyance ratings in an urban environment in ghana.

Zakpala RN, Armah FA, Sackey BM, Pabi O - Scientifica (Cairo) (2014)

Bottom Line: However, there was no statistically significant relationship between neighbourhoods where religious noise exposure was the highest and where noise annoyance was the highest.The magnitude of the noise values for night-time exposure is remarkable particularly given that excessive night-time noise exposure has the greatest detrimental effect on public health.There is the need to focus on vulnerable groups, sensitive hours of the night, and possible confounding with air pollution in order to wholly address this potential hazard.

ABSTRACT
Although accumulating evidence over the past thirty years indicates that noise is an environmental stressor in residential settings, much of the data emanated from studies in high-intensity, noise impact zones around airports or major roads. Little is known about religious noise, especially at night, which is increasingly a growing concern for both the general public and policy-makers in sub-Saharan Africa. Using geographical information systems (GIS), this study measured and mapped exposure to religious noise in a rapidly urbanising municipality in Ghana. Quantitative noise risk assessment was used to evaluate the risk of religious noise-induced hearing loss to residents in the exposed neighbourhoods. The results show that all neighbourhoods where churches were situated had at least one location with significant risk of noise-induced hearing loss. However, there was no statistically significant relationship between neighbourhoods where religious noise exposure was the highest and where noise annoyance was the highest. The magnitude of the noise values for night-time exposure is remarkable particularly given that excessive night-time noise exposure has the greatest detrimental effect on public health. There is the need to focus on vulnerable groups, sensitive hours of the night, and possible confounding with air pollution in order to wholly address this potential hazard.

Mentions: As observed in Figure 2, none of the communities was within the low noise exposure class. A major part of Night Market and small portions of Roman Down and Zongo Laka were in the moderately high noise exposure class. Every part of Jericho, major parts of Market Square, Zongo Laka, and Roman Down, and a small portion of Night Market were in the high noise exposure zone. Every part of New Town, Christian Village, Taifa, and Taboo Line and a small portion of Market Square were in the very high noise exposure class. None of the communities was within the extremely high noise exposure class.
