Measurement and Analysis of Noise Levels: A Study of Selected Pubs in Calabar, Nigeria

Abstract

This research involves the assessment of noise levels in pubs operating in Calabar, Nigeria, to investigate their compliance with the permissible noise level recommended by the National Environmental Standards and Regulations Enforcement Agency (NESREA), Nigeria. A Bam and Kom (BK) Precision 732 digital sound level meter placed on a tripod was used for the measurement of noise levels for three consecutive months, from 6:00pm to 10:00pm. The measured data were subjected to descriptive statistics using excel spreadsheet and the results were presented in the forms of graphs, bar chart and in tabular form. Average equivalent noise level obtained for pubs A, B, C, D and E were 86.5dB, 75.7dB, 75.9dB, 90.0dB and 81.9dB, respectively. Results show that all the pubs under study were in excess of the permissible noise level recommended by NESREA.
