Datasets contained in this article are noise level measurementcarried out at 41 different locations in Ota metropolis, Nigeria. Thenoise readings were measured at a time interval of 30 min for eachsite considered using a precision grade sound level meter. Theanalysis was based on the noise descriptors LAeq,L10,L90,LD, TNIand NEI. Results from the study reflects that the highest and lowestequivalent noise levels (LAeq) were recorded at commercial areas(96 dB (A)) and residential areas (52 dB (A)), respectively, thebackground noise level (L90) has the highest and lowest values atcommercial areas (77 dB (A)) and residential areas (44 dB (A)),respectively and the peak value (L10) has the highest value andlowest value at the commercial areas (96 dB (A)) and residentialareas (56 dB (A)). Based on the WHO recommendations and stan-dards, only 2 out of the 41 locations considered are under normallyacceptable situation while the noise levels of other areas are notacceptable. Noise map developed in this study provides enoughinformation for technical controls and interim legislation againstenvironmental noise pollution in the metropolis. Moreover, con-sidering the noise emission standards, planning and promoting thecitizens awareness about the high noise risk could help to mitigatethe effect of noise in Ota, Metropolis. The noise data in this study are useful as reference and guideline for future regulations onnoise limit to be implemented for urban areas in Nigeria anddeveloping countries at large.
