摘要
The effects of noise on hearing have been assessed among residents of Calabar, Cross River State, Nigeria, using subjective and objective measures. A 39-item questionnaire was used for the subjective measure. A sample size of 1000 persons in the high noise zones (noise level>80 dB(A)) was randomly selected and used as a study group while 1000 persons in the low noise zones (noise level2 ) value of 82.2509 (tabulated X 2=5.22) were obtained. Thus implying that exposure to loud noise does affect hearing of residents in the high noise zones.
