- Exposure to noises contributes to a health risk. There is suficient scientiic evidencethat noise exposure could induce hearing impairment, hypertension and ischemicheart disease, annoyance, sleep disturbances, and decreased school performance. Otherevidence as changes in the immune system and birth defects is limited.The objective of the present research was to determine the effect of cortisollevels to the number of NK cells among women with aircraft noise stress in the area ofAdi Sumarmo Airport, Solo. This study was an analytical survey with a cross sectionaldesign. The number of subjects was 39, who were divided into 3 groups of 13 subjectseach. Groups 1 to 3 were exposed to noise levels of 92.29 dB, 71.79 dB and 52.17 dB, respectively.The sample was taken using simple random sampling. The data were analyzedby Anova followed by post hoc test using LSD test and Pearson correlation test.The Anova test showed that there were signiicant differences in circulating cortisollevels among all groups (p = 0.018). The Pearson correlation test showed that there wasa positive association between circulating cortisol levels and the number of NK cells (r= 0.547; p = 0.000).This study indicated that cortisol levels increased the number of NK cells amongwomen with exposure to aircraft noise. Women which experienced aircraft noise stressshowed increased cortisol levels and the number of NK cells.Keywords : aircraft noise, cortisol, number of NK cells, women
