Let’s get real

Let’s get real, down and dirty, and tell it like it is- straight, cold and clear.
Ignore it or not, it is the real deal and could happen to you and yours.
Pay attention and if you do, your health may improve.

Like poison gas, unsafe sound is odorless, colorless and lethal to your hearing and
harmful to your overall health. It will cause hearing loss, could lead to deafness and is
related to other bad impacts on your physical well being. It is not open to dispute.

The Case For Getting Smart About Sound Research

By STEPHANIE CASTILLO MAY 21, 2013

Research shows that everyday noise affects your body; here’s what you need to know to lessen the effects
“You’ve no doubt heard of the harmful effects loud noises can have on both your hearing and your health. (In fact, we briefly reported on the issue here.) But a study in the May issue of Environmental Health Perspectives gives your body a new cause for concern: everyday noise, such as cell phone rings and conversation. It turns out that those sounds can affect the rhythm and the rate of your heart.
After monitoring 110 adults’ daily heart rate activity and noise exposure, German researchers found that as a person’s exposure to noise increased, so did their heart rate. On the other hand, their heart rate variability, or the time interval between heart beats, decreased. But the lesser the variability, the greater the risk of heart attack, says the study.
Interestingly enough, when the noises stayed below 65 decibels—a hearing safe zone per the Occupational Safety and Health Administration’s (OSHA) standards—participants’ heart rate still went up.
Despite this study finding an immediate effect of noise, sounds below 60 to 65 decibels have not been otherwise shown to have a detrimental effect on health, says Eric Wilkinson, MD, an otolaryngologist with House Clinic at St. Vincent Medical Center in Los Angeles, Calif. OSHA’s threshold for dangerous sound still stands at anything above 80 decibels.
According to the study, there are also other factors to consider. For example, the way a person perceives a sound—annoying or pleasant—could influence their psychological reaction.
Even so, it ahem sounds as if noise at any level can be harmful when not safely sustained. In which case, here are three ways to lessen your exposure:
Know your limit. If you’re going to be in a noisy environment, know how long you can withstand the sound. For your ears, OSHA allows 8 hours a day for sounds at 90 decibels, four hours for 95 decibels and only two hours for 100 decibels. These sounds include semi-trailers, lawn mowers and weed-whackers. For a complete list, visit OSHA’s website. But also pay attention to how your body reacts to these sounds, do you find yourself anxious? If so, it may be a sign that your heart rate is increasing. Take measures to find quiet.
Download a sound meter!!!. How do you know if a place you’ve found is truly quiet? By personally measuring sound levels with an app for your smartphone. “A lot of situations are a lot louder than you think,” says Dr. Wilkinson. With a sound or volume meter, you can see how loud a room really is—or isn’t—and if it would be in your heart’s best interest to stay. As a bonus, most apps will warn you if the sound should be sustained with or without further protection, such as ear plugs. (Check out more apps great for your health.)…….

Negative consequences of noise on overall health

Summary:

The combined toll of occupational, recreational and environmental noise exposure poses a serious public health threat going far beyond hearing damage, according to an international team of researchers.
The combined toll of occupational, recreational and environmental noise exposure poses a serious public health threat going far beyond hearing damage, according to an international team of researchers writing today in The Lancet. The review team, including a Perelman School of Medicine at the University of Pennsylvania expert, examined the latest research on noise’s impact on an array of health indicators — hearing loss, cardiovascular disease, cognitive performance and mental health, and sleep disturbance — in order to inform the medical community and lay public about the burden of both auditory and non-auditory effects of noise.

“In our 24/7 society, noise is pervasive and the availability of quiet places is decreasing. We need to better understand how this constant exposure to noise is impacting our overall health,” said Mathias Basner, MD, PhD, MSc, assistant professor of Sleep and Chronobiology, Department of Psychiatry at Penn, and lead author of the new review. “From earbuds blasting music during subway commutes to the constant drone of traffic heard by those who live or work near congested highways to the beeping of monitors that makes up the soundtrack heard by hospital patients and staff, what we hear all day impacts many parts of our bodies.”

Occupational noise and its negative impact on hearing has been the most frequently studied type of noise exposure. But in recent years, research has broadened to focus on social noise, such as noise heard in bars or through personal music players, and environmental noise from road, rail, and air traffic. “Our understanding of how different types of noise impact aspects of health other than hearing loss, including sleep, cardiovascular function, community annoyance, and even a patient’s ability to heal in a hospital environment, is continuously increasing,” Basner said.

With both noise-related hearing issues (auditory) and broader deleterious effects of noise on physical and mental wellbeing (non-auditory) in mind, the research team — consisting of members from the International Commission on Biological Effects of Noise (ICBEN), a global panel of experts in various areas of noise and public health — convened to summarize current findings related to noise exposure and overall health. The team concentrated on studies published during the past five years in the fields of otolaryngology, cardiovascular medicine, sleep medicine, psychology, and hospital medicine to best determine the state of current evidence of noise’s impact on health.

In general, the medical community knows that high noise levels can cause hearing loss, as noise-induced hearing loss is the most common occupational disease in the United States. “Approximately 22 million U.S. workers are exposed to hazardous noise levels at work, and, annually, an estimated $242 million is spent on compensation for hearing loss disability,” said Basner. Preventive and therapeutic compounds to treat noise-related hearing loss are being developed and will probably be available within the next 10 years, but the authors stress that additional educational efforts need to be planned in order to prevent the aging population from unnecessary hearing loss.

Relating to non-auditory effects, the authors conclude that because of the ubiquitous exposure of environmental and social noise, its public health effect is easily underestimated. According to the World Health Organization (WHO), more than one million disability adjusted life years are lost in western European member states alone due to environmental noise exposure, most of these caused by sleep disturbance and community annoyance.

Accordingly, the authors found evidence that long-term exposure to environmental noise affects the cardiovascular system, with connections to hypertension, ischemic heart diseases, and stroke. In addition, numerous studies pointed to associations between environmental noise exposure and sleep disturbance, children’s cognition, and negative effects in hospitals for both patients and staff.

The authors note that for auditory effects, there is still debate about what noise levels are considered safe, and that prospective studies with adequate control groups could help shed additional light on the discussion. For the non-auditory effects, Basner says large-scale prospective epidemiological studies, dedicated primarily to the health effects of noise, are needed to strengthen the link between acute and long-term environmental and social noise exposure and the various health outcomes, especially cardiovascular disease.

The authors hope that their review will increase awareness about the manifold negative health consequences of noise, and stimulate educational campaigns for children and adults that will promote both noise-avoiding and noise reducing behaviors, and thus, mitigate negative healthconsequences. “Efforts to reduce noise exposure will eventually be rewarded by lower amounts of annoyance, improved learning environments for children, improved sleep, lower incidence of cardiovascular disease, and, in the case of noise exposure in hospitals, improved patient outcomes and shorter hospital stays,” they conclude.

Basner and colleagues at Penn have just been awarded federal funding through the Federal Aviation Administration (FAA) to study the impact of aircraft noise on sleep and work on developing models that predict sleep disruption for different aircraft noise levels and profiles.
