The article objective is to study the health hazards that arise from the noise produced during civil construction activity and to determine the frequency distribution of the noise amplitude using the fast Fourier transform technique. Samples of sound were recorded using standard calibrated recording devices. The samples were analyzed using the fast Fourier transform technique to obtain the frequency distribution of the noise amplitude. The noise power was estimated using the square of the amplitude. The noise amplitude spectra of different samples of noise collected from civil construction sites were successfully determined using the fast Fourier transform technique. It was found that most of the noise produced during civil construction activity was situated within the frequency spectrum to which the human ear is most responsive. The results of this study show that the noise produced during civil construction activity is a type of broadband noise occupying the region of frequencies to which the human ear is most sensitive. Therefore, such noise is capable of causing harm, including hearing impairment, to people in the vicinity of construction sites.
