Most human activities in construction sites, transport, housing, commercial, industrial, educational, recreational, social and religious generate noise. In Nigeria, there are no noise ordinances or laws and so noise generators exceed limits and constitute noise nuisance without being investigated or reprimanded. In educational institutions, no serious brain work can take place in a noisy environment. The objective of the paper was to investigate noise pollution in the various noise zones in Abia State University and compare them with World Health Organization Standards. Noise sources and the sensitive receptors in the study area were identified. Baseline ambient noise monitoring was carried out at the representative receptors to determine existing ambient noise levels for the noise zones. Results showed that the mean noise levels for the various noise zones were higher than the World Heart Organization Standards. The higher noise levels could be attributable to student gossips and the use of some lecture halls as churches using microphones and loudspeakers, playing of musical instruments and the use of own electricity generating sets in off-campus residential areas. It is therefore recommended that the lecture halls should be provided with acoustic materials using sound proof techniques. There is the need to set up noise standards and regulatory limits for different noise zones in Nigeria.
