Effect of race upon noise induced hearing pattern

ABSTRACT

Hearing of 2 groups of workers were compared to study the effect of race on noise induced deafness. The first group consisted of 40 Filipino workers and the other included 40 Indian workers. Matching was done for type of noise dosimetry were done for all workers included in the study. The mean age of workers was 33.87 +/- 4.02 years, while they spent 5.67 +/- 2.24 years exposed to noise which had an average level of 92.85 +/- 6.07 dB. The results indicated that both groups had a similar audiogram pattern for both right and left ears. No significant differences were observed between the 2 groups regarding the level of hearing at the measured frequencies. Both groups showed mild functional loss of hearing with no significant differences of the mean functional hearing loss of Filipinos [4.4017 +/- 4.138%] and Indians [4.4444 +/- 3.999%]
