Noise Pollution: A Ubiquitous Unrecognized Disruptor of Sleep?


Noise Pollution: A Ubiquitous Unrecognized Disruptor of Sleep?

That’s a question I wish I didn’t have to pose as we have just entered the year 2014. Now accounting for over 70% of modern offices, it is safe to say the open-plan phenomenon is here to stay. If you wish to make a complaint about noise, please contact Environmental Health. This has been going on for ages and effects of extreme noise pollution are being felt now. Pick up the phone and call a relative whose silence you would like to turn into a vibrant and joyful conversation. These are contentious fields of sleep research that are of growing importance relative to the somewhat forgotten role of environmental exposure in sleep health. Medical researchers at the Karolinska Institutet in Stockholm added weight gain to the potential impact of noise on public health.

Rickshaw drivers were about thrice as likely to he screened as hearing impaired by the SHs questionnaire (RR 2.9, 95% confidence interval 1.6, 5.0), twice as likely to report tinnitus (RR 2.2, 95% confidence interval, 1.1, 3.3) and two and a half times as likely to have difficulty in following telephonic conversations (RR 2.4, 95% confidence interval 1.2, 4.8). For inexplicable reasons, noise related sleep disturbance does not seem to have been an issue that attracted much scientific enquiry before 1963, as evidence by the fact that Nathaniel Kleitman3 in his seminal tome Sleep and Wakefulness does not mention this subject despite basing his book on 4,337 references—which even includes one on William Shakespeare’s favoured sleeping position’ The public health impacts of noise began to emerge as an issue in the 1960s, however.

The complaint was that “the activities of Pokemon GO players have disturbed the peacefulness of the area,” and the police responded. 001). This type of noise can be easily solved with the installation of acoustic barriers, creating a quieter environment for patrons and neighbors. Watch out if you feel like lighting those red ‘ladi’ string bombs and other smoke-emanating fireworks at Diwali.

In addition, the team says the findings are consistent with a large number of previous studies linking road traffic noise and high blood pressure, a leading cause of stroke. The doef doef doef you get from these boom boxes on wheels. Unwanted and uncontrolled sound is not only counterproductive, but can get in the way of a room’s intended purpose. I don’t know why, but this noise causes some kind of anxiety and tension. There can be dilemmas on how to treat field data, for example with the effects of aircraft noise on the sleep of local residents where noise from a passing aircraft could wake a child or the family dog, who then wakes the entire household. There are no easy answers to these issues other than to conduct both laboratory and field studies in the best possible scientific manner and develop a composite picture that best fits the laboratory and field data. There is a recent controversy whether physiological responses to noise during sleep have meaningful health consequences that are amenable and valid for the construction of dose-response (noise level-physiological) curves.7–9 However, it has been established that long-term traffic exposure, especially at night, increases the risk of cardiovascular disease.10 It has also been demonstrated that noise-induced cardiac arousals do not habituate across nights of study,5,11 which underlines their potential relevance in the long-term cardiovascular consequences of noise-induced sleep disturbance.

The crux of the issue that is yet to be resolved is this—what is the mechanism by which noise-disturbed sleep could lead to significant reduction in health? My heart was pounding. The light does hit it, but just so widely spread it’s hardly detectable. Recurrent or permanent tinnitus can be a symptom of hearing loss and damage. Michael Hogan and Gary L. The Base Syndrome. Test et al.

compared 99 hearing impaired (25dBA down in the 1 kHz-4 kHz range) workers with 199 with no hearing impairment and found tinnitus was the most prevalent sleep disturbing factor, with 75% higher score among those affected (P = 0.001). First, the effect is very small, but is growing at a much faster pace we grow older. Double hearing protection means wearing both ear muffs and ear plugs at the same time. This may happen so gradually and painlessly that you may not notice the minor deterioration from one day to the next. In addition, they had relatively large sample sizes, all attended the same Occupational Clinic, were tested by the same method and the hearing was assessed by the same audiometric equipment.2 They also indicated some weaknesses: the reliance on self reported sleep quality despite using a validated tool (Mini Sleep Questionnaire), and hearing assessment was restricted to one test that required the cooperation of the subject and the timing varied across the work shift. Most of these shortcomings could be relatively easily rectified in future work. There is a very large grey area about what amount of noise is acceptable or not, it is mainly due to this that many problems occur.

However, this was a well-designed study with clear results that need to be replicated in other noisy working environments to fully gauge the general applicability of its findings. These two studies clearly highlight that need for sleep research to focus on the role of environmental variables—especially noise—on sleep health in a world in which noise from many sources is a 24-hour phenomenon of increasing public health concern.
