Abstract

Effects on the systemic circulation, such as the constriction of blood vessels, have been observed under laboratory and field conditions. A 39-item questionnaire was used for subjective assessment of the respondents in all the sixteen zones. The respondents were given questionnaires which contained standard questions tailored toward getting their reactions about the effects of noise on them. The effect of noise on blood pressure was assessed by comparing the blood pressure of respondents who had lived or worked/schooled in the high noise zones with that of respondents in the low noise zones. The respondents taken were those that have lived in these areas for at least three years, a period believed to be enough for adaptation to the noise environment by the respondents.
