Indoors and outdoors ambient noise levels were measured within the RSUST to determine the levels and sources of noise pollution within the university campus in order to ascertain if the noise level has exceeded acceptable limit to affect the air quality of the environment and also access the impact of various activities in the university with regard to noise pollution. Noise levels were measured with a digital sound level meter model 407730 manufactured by EXTECH instruments with “A” weighting scale. The measured noise levels ranged between 47.8 dB (A) and 103.2 dB (A). The mean noise levels recorded around the 2000 KVA and 1275 KVA generators exceeded the permissible noise levels guideline of 90dB (A) recommended by Occupational Safety Health Agency and Federal Ministry of Environment while all the mean noise levels measured within the university exceeded the guideline values of 35 – 55 dB (A) set by World Health Organization. High positive correlation coefficients between indoor and outdoor were recorded. Analysis of variance on noise levels between hostels, road junctions, gates and Departments showed significant difference (P < 0.05). Noise levels at outdoors were generally higher than indoors. t - test on the mean noise levels between indoor and outdoor were not significant (P > 0.05) but t - test between maximum and minimum noise levels and between the Departments were significant (P < 0.05). The measured noise levels were typical of urban communities in developing countries. In addition to steady electricity supply from National grid, solar plant or sound proof generators were recommended.
