Study of noise pollution during pre-carnival, carnival and post-carnival periods in Calabar
Municipality has shown that the municipality is always highly polluted with noise from vehicles, facilities of
transportation, drumming, trumpeting, shouts, knock-outs, firecrackers etc. during the carnival festival.
Noise levels as high as 77.4 to 102.2 dB(A) which far exceed the 60 to 65dB(A) permissible out-door level
have been recorded. Average noise levels of 94.9 dB(A) in the morning, 84.0 dB(A) in the afternoon and
96.1 dB(A) in the evening were obtained during the carnival period while 80.8, 75.9 and 83.1dB(A) , 80.7,
75.7 and 82.1dB(A) were average levels for morning, afternoon and evening of pre and post carnivals
respectively. The lowest noise levels were in the afternoons when comparing these three investigating
periods, 70.7 dB(A) at site 6 in pre-carnival, 77.4 dB(A) at site 10 in carnival and 70.5 dB(A) at site 6 at
post-carnival and the number of vehicular and other human activities during the day time reduce
tremendously. The citizenry who are made up of the youth, middle aged and the old stand the risk of
endangering their health physically, psychologically or socially due to noise generated during this festival.
