Dangers of Noise

Discussion on technology and how it could be used to assist spiritual development and NOT enslave us. This includes technology that will help us live in harmony with Nature (e.g.: "Lifter" technologies that could replace the petrol driven engine). Also, discussion of past and current scientific thought so that gems are not buried in the sands of time, and spiritual progress through science is achieved.

Dangers of Noise

Post: # 3382Post Vesko »

A new study confirming the importance of what is written about noise in Michel's book (News is courtesy of Zark.) All amazing things that directly relate to Michel's book.

March 6, 2005: "Noise is Sydney's No.1 Enemy"
http://www.sundaytelegraph.news.com.au/ ... 78,00.html
The State Government will introduce tough regulations to reduce noise pollution after a study found it was the biggest source of stress and aggravation in our cities.
The study revealed people blamed noise for eroding the quality of urban life, placing it higher than littering, vandalism, drug abuse and youth crime as a source of concern.
In response to the findings, Cabinet last week moved to give council and Department of Environment and Conservation (DEC) officers the power to disable car and house alarms that fail to shut off.
Under present laws, authorities are powerless to turn off an alarm. Instead, an on-the-spot fine is used as a deterrent.
Environment Minister Bob Debus said officers would be required to obtain a warrant to enter a home to shut down an alarm.
"Unfortunately, consideration for others is falling by the wayside for many people living within earshot of one another," Mr Debus said.
"Noise from car or home burglar alarms can cause considerable disruption in the neighbourhood."
The State-wide survey of 750 residents, commissioned by the Government, was conducted as part of a five-year review into noise regulations.
Almost half the residents who took part in the survey listed traffic noise as the biggest problem in their suburb.
Litter and rubbish followed, with barking dogs third.
Young people misbehaving was next, followed by dog droppings, graffiti and vandalism.
Almost a quarter blamed noisy neighbours for affecting their quality of life.
Motorcycles and modified cars topped the list of most annoying noises.
Noise from pubs and entertainment venues followed, with loud music, barking dogs, pool pumps and garbage-collection trucks also high on the list.
World Health Organisation research has found that noise can have serious health risks.
Noise at 70 decibels increases the risk of a heart attack by 20 per cent. Ambient noise at 80 decibels on a regular basis begins to cause permanent damage to the hearing system.
And at 90 decibels, a person can experience an adrenalin rush that triggers hostility. Hearing loss kicks in after just seven and a half minutes at 120 decibels.
The Department of Environment and Conservation's Pollution Line said it had received 2268 noise-related calls in the past six months.
More than 400 of those were about noisy air-conditioners, pool pumps, fans and compressors. And 383 - 16 per cent of the total - were complaints about noise from pubs, clubs and businesses.
Eleven per cent of the calls were about noisy neighbours, with 263 people ringing in to complain about loud voices, blaring TV sets and even energetic sex.
Residents who complain about noise can contact their local council or ring the department's Pollution Line.
Noise comes high on complaints made to local councils.
In Randwick, 381 complaints about noise were made last year - 289 of them about noisy dogs. In Fairfield, Fido was also driving the neighbours barking, with 181 of 294 noise-related complaints about loud dogs.

The effects of noise pollution to humans can be harmful and annoying especially if you’re trying to sleep, it must be stressful being an insomniac, but I wonder about the effects on animal life..

Certainly noise pollution and military experiments underwater have affected blue whales and their ability to navigate and gather food because they rely on acoustic communication in their daily lives and now that’s being messed with

InfoSource, that's one super article! Thank you very much!

From the article, the so-called acoustic smog has reduced their communication ability tenfold. And...
Noise pollution is doubling every decade in an urbanized marine environment, Clark claims, mostly due to shipping traffic.
"Whales have shown remarkable resilience to cataclysmic events — until the last one — which is us," said Steve Palumbi of Stanford University’s Hopkins Marine Station. "Ice ages, sea level change and even loss of local food sources did not interrupt their lives. Living in a fluid environment, they could move to new areas of productivity and find food even as the climate around them changed."

“The effect of night-clubbing: continuous, loud music and the toxicity of methamphetamines”. For this study mice were put on ecstacy and exposed to booming techno music. The scientific result is that night-clubbing can cause “long-term stereotypy and an adulterated locational preference” (???)
7 mice died and more of them got a permanent brain damage. That’s why the British Union for the Abolition of Vivisection (BUAV) explained that those dead mice were martyrs of useless scientif examinations and started a legal war, that resulted in stopping any further experimentation on this field.
This is the information i got from a website. It doesn't seem to contain enough information.

Effects of loud noise exposure on DNA integrity in rat adrenal gland
Frenzilli G, Lenzi P, Scarcelli V, Fornai F, Pellegrini A, Soldani P, Paparelli A, Nigro M
ENVIRONMENTAL HEALTH PERSPECTIVES
112 (17): 1671-1672 DEC 2004

Document type: Article Language: English Cited References: 26 Times Cited: 0

Abstract:
Loud noise is generally considered an environmental stressor causing negative effects on acoustic, cardiovascular, nervous, and endocrine systems. In this study, we investigated the effects of noise exposure on DNA integrity in rat adrenal gland evaluated by the comet assay. The exposure to loud noise (100 dBA) for 12 hr caused a significant increase of DNA damage in the adrenal gland. Genetic alterations did not decrease 24 hr after the cessation of the stimulus. We hypothesize that an imbalance of redox cell status is responsible for the induction and persistence of noise-induced cellular damage.

59 (2): 136-146 OCT 15 2002

Document type: Article Language: English Cited References: 87 Times Cited: 0

Abstract:
Noise represents an environmental stress factor affecting several organs and apparati, including the cardiovascular system. In experimental animals undergoing noise exposure, subcellular myocardial changes have been reported, especially at mitochondrial level; in particular, after 6 hours of exposure only the atrium exhibited significant mitochondrial alterations, whereas after 12 hours as well as subchronic exposure both atrium and ventricle were damaged. The first part of the present article overviews the experimental evidence on effects of noise on the myocardium. In the second part, the review analyzes the role of benzodiazepine receptors and the potential efficacy of benzodiazepine ligands in preventing the mitochondrial damage induced by noise exposure. Drugs acting at both central and peripheral benzodiazepine receptors significantly prevent this damage. Differences in the amount and the duration of the protective effect might depend on variability in the potency and pharmacokinetics of the specific drug. The effects of the combined treatment with selective and non-selective peripheral benzodiazepine ligands on noise stimulation are discussed at biochemical level reviewing studies on the effects of noise exposure on mitochondrial fractions.

DNA damage associated with ultrastructural alterations in rat myocardium after loud noise exposure
Lenzi P, Frenzilli G, Gesi M, Ferrucci M, Lazzeri G, Fornai F, Nigro M
ENVIRONMENTAL HEALTH PERSPECTIVES
111 (4): 467-471 APR 2003

Document type: Article Language: English Cited References: 45 Times Cited: 1

Abstract:
Noise exposure causes changes at different levels in human organs, particularly the cardiovascular system, where it is responsible for increasing heart rate, peripheral vascular resistance, and blood pressure. In this study,we evaluated the effect of noise exposure on DNA integrity and ultrastructure of rat cardiomyocytes. The exposure to loud noise (100 dBA) for 12 hr caused a significant increase of DNA damage, accompanied by. swelling of mitochondrial membranes, dilution of the matrix, and cristolysis. These alterations were concomitant with increased in situ noradrenaline levels and utilization. Genetic and ultrastructural alterations did not decrease 24 hr after the cessation of the stimulus. An elevated oxyradical generation, possibly related to altered sympathetic innervation, is hypothesized as responsible for the induction and persistence of noise-induced cellular damage.
Effects of loud noise exposure on mouse myocardium: A comparison with the rat
Gesi M, Lenzi P, Fornai F, Ferrucci M, Soldani P, Pellegrini A, Paparelli A
MICROSCOPY RESEARCH AND TECHNIQUE
59 (2): 131-135 OCT 15 2002

Document type: Article Language: English Cited References: 19 Times Cited: 0

Abstract:
Loud noise is an environmental stressor of everyday life, which affects different organs and apparati, in particular the cardiovascular system. We have already reported that noise exposure produces significant alterations in the rat myocardium, consisting of mitochondrial damage, which is evident as lysis of the cristae and dilution of the matrix. Since there are high similarities between mouse and human species, the aim of our study was to investigate the effects of acute noise exposure on the mouse heart. We found that noise exposure affects mouse myocardium at similar subcellular sites to those already described in the rat; nonetheless, quantitative analysis of the percentage of altered mitochondria in both species disclosed a clear difference between mouse and rat myocardium, which strongly suggests a different sensitivity to noise stimulus. We hypothesize that the species differences on the extent of myocardial alterations here observed might be due to the zonal pattern of cardiac noradrenergic receptors, which should be the final effectors for noise-induced myocardial changes.

It seems that the research is not taken seriously as the number of citation of the articles are LOW.

Do you guys think we might be able to get the attention of some environment groups with these articles?
