The Comparison of Hearing Capabilities and Blood Pressure with Reference to Noise Pollution in Rural/Urban Areas of District Hyderabad
Keywords:
Urbanization, noise pollution, hearing impairment, blood pressure.Abstract
OBJECTIVE: To compare the noise pollution and blood pressure in urban and or rural areas of Hyderabad,
Sindh, Pakistan.
METHODOLOGY: A comparative cross sectional study was conducted from April 2018 to September
2018. The sample size was randomly selected 201 young adults of either gender between 18 to 25 years
of age.
RESULTS: The hearing frequency in rural female (29.34Hz±8.04) was significantly (p<0.05) less than the
urban female (49.09Hz±7.76). Similarly, the hearing frequency in rural male (24.72± 7.0) was also
significantly (p= <0.05) less than that of urban group (40.56Hz±7.6). The systolic and pulse pressure
(106.2mmHg±4.35and 38.88mmHg±4.8) was recorded significantly (p=<0.05) lower in rural than Urban
female (114.2mmHg±6.03and45.76±4.8). Moreover, the systolic and pulse pressure
(108.3mmHg±5.40 and 42.4mmHg±4.71) was significantly (p=<0.05) lower in rural than urban males
(114.2mmHg±6.00 and 47.33mmHg±5.00mmHg) respectively.
CONCLUSION: The study concludes that noise pollution has potent impact on hearing capabilities and
blood pressure in urban areas of district Hyderabad, Sindh, Pakistan
