The Us

Objectives: Over half the US population experiences noise levels above WHO recommendations yet little research within the US has examined the health effects of these exposures. Our objective is to investigate the associations between community noise and blood pressure in residents of Chicago. Methods: Participants were from two prospective cohort studies: the Multi Ethnic Study of Atherosclerosis (MESA) and the Chicago Health and Aging Project (CHAP). MESA is a multi-site study of persons aged 45-84 years and free of clinical cardiovascular disease. CHAP is an open cohort initiated to study chronic conditions of aging among persons aged ≥65 years. This analysis focuses on the 5,167 participants of these cohorts living in Chicago with an average of 2.5 (CHAP) and 4.5 (MESA) assessments per participant, for systolic (SBP) and diastolic (DBP) blood pressure between 1999-2011. In both cohorts, hypertension was defined as taking antihypertensive medication, SBP ≥140 or DBP ≥ 90 mmHg. We estimated noise at participant addresses using land use regression models weighted according to participants’ 5-year residential history before each exam. Among those taking antihypertensive medication, blood pressure was adjusted using multiple imputation. Associations between noise and blood were estimated using linear mixed models. A Cox proportional hazards model was used to estimate relative risk (RR) of incident hypertension. All models included calendar time, age, sex, race, income, education, neighborhood socioeconomic score, smoking, cohort, interaction between cohort and age, race, and gender, and NO x (a traffic-related air pollutant). Findings : At baseline, MESA participants were younger (63 vs 73 years) and more educated (36 vs. 3% with ≥graduate degree) than CHAP participants. MESA participants had higher noise levels (60 vs 56 dB) and lower blood pressures (e.g. SBP: 124 vs 135 mmHg) than CHAP participants. After adjusting for cohort and other confounders, we found that 10 dB higher residential noise levels were associated with 0.9 (95% CI: -0.2, 0.2; p=0.1) and 0.5 mmHg greater (95% CI: -0.1, 0.11; p=0.08) SBP and DBP, respectively. Similar associations were found within each cohort. Noise was not associated with incident hypertension overall (RR: 1.00; 95% CI: 0.8, 1.3, p=0.98) or within cohort. Conclusions: We found a suggestive association between noise and blood pressure levels, but no association with hypertension. This could be due to the lack of nighttime noise information, which has been shown to be more strongly associated with blood pressure outcomes than daytime levels or with the selection of healthy older participants.

Noise Metrics

As drone package delivery services are expanded, community noise will be an issue that every operator will need to consider. Drones represent a unique new community noise source that will operate and be perceived differently than traditional aircraft and ground transportation vehicles. It is also likely that some early implementations of drone delivery services by major retailers will operate out of existing distribution centers, which may not be ideally located from a noise perspective. This study considers potential drone delivery noise in the community surrounding an existing distribution center, assuming the facility were to be utilized as the hub of a future drone package delivery service. The predicted noise levels from drone deliveries are compared to typical community noise limits, and potential alternative noise metrics for assessing annoyance from drone noise in communities are discussed. Options to reduce community noise from drone deliveries by altering flight altitude and speed, utilizing different flight path routing strategies, and taking advantage of the potential masking of drones by existing roadway noise are considered.

Exposed Population

Noise pollution is an interfering air-pollutant which possesses both auditory and a host of non-auditory effects on the exposed population. Since there is no medicine to cure hearing loss prevention to overt exposure is the only alternative left. The study reports community noise levels measured during day time in a fast developing semi-urban area of Nepal. The noise levels were measured following standard procedure using calibrated sound pressure level meter at many places predominated by both commercial and residential tenements at Banepa town particularly reflecting motor vehicular traffic prone areas. A small exercise of nose generated by different vehicles that frequent on the arterial roads has also been carried out. To delineate the perception about the noise and its significance on health of community a representative sample of public has been interviewed using a questionnaire. The results indicate high noise levels, surpassing on many occasions to the prescribed levels. Overall minimum and maximum noise levels for the Main Road are 60.1dB (A) and 110.2 dB (A). Bus parks and Bus stops had minimum and maximum noise levels were 63.9 dB (A) and 110.2dB (A). The picture near residential tenements also had substantial levels of noise, a minimum of 59.11dB (A). The noise levels produced by different motor vehicles ranged from 121 to 91.2 dB(A), which was substantial. The study observes motor vehicles as main source in the town. The perception survey indicate high prevalence of head aches, lack of concentration, sleep. Since levels lie much above the prescribed limits there is am imminent health risk to the exposed population and the study suggests control measures to be instituted on a priority.
