21.01.2022 The Loudest Underwater Sound Ever Recorded Bloops are some of the loudest sounds of any type ever recorded in Earth's oceans, their origin remains unknown. The Bloop sound was placed as occurring several times off the southern coast of South America and was audible 5,000 kilometers away. ... Although the sound has similarities to those vocalized by living organisms, not even a blue whale is large enough to croon this loud. The sounds point to the intriguing hypothesis that even larger life forms lurk in the unexplored darkness of Earth's deep oceans. A less imagination-inspiring possibility, however, is that the sounds resulted from some sort of iceberg calving. No further Bloops have been heard since 1997, although other loud and unexplained sounds have been recorded. Source: http://apod.nasa.gov/apod/ap100427.html

20.01.2022 Traffic noise and lack of green space in large cities heighten the risk of stroke Road traffic noise has been linked to heart disease and its complications in earlier studies. But there is scant research assessing the possible influence of this form of noise pollution on the risk of stroke, a medical condition that has the same risk factors as heart disease. To this end, the international team of scientists studied the data of 2,761 patients that had been hospitalized for isc...Continue reading

When city planners and engineers were asked to design a new train some ten years ago, instead of demolishing people’s homes, they designed one that runs through them. ...

17.01.2022 ...The World Health Organization has calculated that at least 1m healthy life-years are lost every year in western European countries because of environmental noise, with cardiovascular disease contributing to the vast majority of these deaths, especially high blood pressure, heart attacks and coronary heart disease. It is thought that noise triggers the release of the stress hormone cortisol, which damages blood vessels over time. Humans evolved our acute hearing millions of... years ago, when we were prey animals and had to pinpoint predators, so it is no wonder we find noise stressful. It is hardwired. A leading acoustics engineer, Trevor Cox, hypothesises that the noises we find most stressful are distress calls screams with an unhinged roughness to them, caused by the vibrations of the vocal folds when someone is truly terrified. The frequencies are similar to the archetypal horrible sound, fingers scraping down a blackboard; and to an electric drill angrily ripping through plasterboard.... https://www.theguardian.com//sonic-doom-noise-pollution-ki

11.01.2022 Earth’s Quietest Place Will Drive You Crazy in 45 Minutes Inside the room it’s so silent that the background noise measured is actually negative decibels Everybody seems to be looking for a little peace and quiet these days. But even such a reasonable idea can go too far. The quietest place on earth, an anechoic chamber at Orfield Laboratories in Minnesota, is so quiet that the longest anybody has been able to bear it is 45 minutes.... Inside the room it's silent. So silent that the background noise measured is actually negative decibels, -9.4 dBA. Steven Orfield, the lab's founder, told Hearing Aid Know: We challenge people to sit in the chamber in the dark one person stayed in there for 45 minutes. When it’s quiet, ears will adapt. The quieter the room, the more things you hear. You’ll hear your heart beating, sometimes you can hear your lungs, hear your stomach gurgling loudly. In the anechoic chamber, you become the sound." But the room isn't just for torturing people. Companies test their products in it to find out just how loud they are. And NASA has sent astronauts to help them adapt to the silence of space. For you and me, however, the room is a deeply disorienting place. Not only do people hear their heartbeat, they have trouble orienting themselves and even standing. "How you orient yourself is through sounds you hear when you walk. In the anechnoic chamber, you don't have any cues," Orfield told the Daily Mail. "You take away the perceptual cues that allow you to balance and manoeuvre. If you're in there for half an hour, you have to be in a chair." So the next time you wish for some quiet time, remember that it could also drive you crazy. https://www.smithsonianmag.com//earths-quietest-place-wil/

07.01.2022 https://prestigeplus.sydney/soundproof-windows/ Soundproof Windows If you live in an urban area, the noise pollution from traffic and construction can be very annoying. In fact, it is possible that an excessive amount of noise can even lower the value of your property as well as affect your health, comfort & quality of life. ... Installing soundproof and noise reduction windows are the best way to stop the noise from coming or going out of your house. How do you make windows soundproof? The easiest and most effective way is to add a laminated layer to the double glazing unit to stop the noise. This is installed on the inside part of the window sill and cannot be seen from outside. It stops the noise and makes the property a more pleasant space to work or relax in. How does it work? Soundproof windows work by repelling soundwaves. The windows repel the noise by combining thick glass and laminated glass in the double glazing unit. Patterned, toughened or wired glass behave differently when it comes to acoustics, the lamination of the different glass types suppresses sound due to the interlayer in between. There are special acoustic grades of laminated glass which has two glass sheets and a layer of acoustic resin. Benefits Windows are the greatest source of noise entering the room. Soundproof and noise reduction windows stop unwanted noise from entering the house. Additionally, if you have a passion for music or desire to own a great sound system soundproofing your windows would ensure you have no complaints from your neighbours. How do you make a room soundproof? A room consists of building elements other than windows that can let in unwanted noise. In addition to soundproofing your windows, some of the other factors that can be considered while making your room soundproof are; Install double glazed doors that have similar soundproof qualities as double glazed windows Seal your doors with weathering strips Cover bare walls and ceiling with something soft to reduce reflected noise Fix loose floorboards Replace your hollow internal doors with solid doors These steps give you a completely soundproof room, a place where you can escape from the outside world and experience peaceful bliss. https://prestigeplus.sydney/soundproof-windows/

06.01.2022 We are born with just two innate fears the fear of loud sounds and the fear of falling. Everything else is a learned fear, influenced by our culture and environment.

04.01.2022 Why ‘Pink Noise’ Might Just Help You Get a Better Night’s Sleep Pick both the sound and volume that you find relaxing What the science says (and doesn’t)... In one study, pink noise increased deep sleep and dramatically improved memory in older adults. The pink noise actually enhances brain activity that’s associated with deep phases of sleep, Dr. Drerup explains. The researchers aren’t claiming that pink noise is better than white noise. (There hasn’t been research comparing the two types of sound.) They may both help, she says. But it’s important to note that the exact technology used in the study isn’t the same as what you’ll find in a sleep app or on YouTube. It’s not widely available. The apps will probably help, but not to the same level..... ******************************************************************* Pink Noise for Sleep, Relaxation, Meditation, Concentration, Studying and Tinnitus Masking https://www.youtube.com/watch?v=nISbX0TU2HE
