Abstract

Noise pollution has been shown to be a global health hazard and this could be aggravated by the use of noise-emitting generators. Therefore, this study aims to determine the Sound Pressure Levels $(SPLs),$(SPLs), Sound Power Levels $(L_W)$(LW) as well as Noisiness of sixty different models with various Power-ratings from fourteen generator brands, commonly used in homes/offices in seven cities covering South-Southern Nigeria. The results obtained between January 2013–December 2015 showed that for nearly all generator brands, models and ratings, the values of $SPL$SPL were above the Permissible Noise Exposure Limits $(PNELs)$(PNELs) recommended by $WHO,$WHO, $USEPA$USEPA and $EN$EN of $90dB(A),$90dB(A), $75dB(A)$75dB(A) and $70dB(A)$70dB(A) respectively for $8hour$8hour daytime safe human exposure. Also, the ‘Wilcoxon Signed Ranks Test’ analyses showed that the three (3) alternative hypotheses $[H_a:SPL \gt 90dBA]$[Ha:SPL>90dBA], $[H_a:SPL \gt 75dBA]$[Ha:SPL>75dBA] and $[H_a:SPL \gt 70dBA]$[Ha:SPL>70dBA] are statistically-significant and should be accepted – further implying that: the decibel-ratings of majority of these generator-models are evidently hazardous.
