Noise pollution is becoming a major threat to the welfare of wildlife, according to a scientific review.Sounds produced by vehicles, oil and gas fields and urban sprawl interfere with the way animals communicate, mate and prey on one another.
Dr Jesse Barber and Dr Kevin Crooks of Colorado State University and Dr Kurt Fristrup of the US National Park Service reviewed all recent scientific studies examining the issue.
Female grey tree frogs (Hyla chrysoscelis) exposed to the sounds of passing traffic take longer to locate and find calling males, while European tree frogs (Hyla arborea) call less overall. For example, one gleaning bat species, the Bechstein's bat (Myotis bechsteinii), is less likely to cross roads than other bat species that forage in open areas, suggesting the noise of the traffic could fragment their hunting grounds. IBM is doing all kinds of stuff in this noise-free world, from making making computer chips the size of human cells to silly stuff, like making the world’s smallest movie starring a bunch of atoms. Microsoft's Anechoic Chamber has set the Guinness World Record for the Quietest place on Earth. The previous record for the Quietest Place on Earth was -13 dB held by an Eckel anechoic chamber at Orfield Laboratories in Minneapolis. The anechoic chamber at Orfield Labs is reportedly so quiet that you can hear your own heartbeat, lung flow, stomach and inner ear noises.
Eckel Vice President Jeff Morse says in a statement, "We are absolutely thrilled with the results of our chamber for Microsoft.
We welcome you to world’s quietest room, located in Zurich, Switzerland where it is being used by IBM. The sounds are becoming so ubiquitous that they may threaten biodiversity, say the review's authors. Crucially, both species appear unable to change their calling habitats to overcome the din from the roads, potentially compromising their ability to reproduce. Despite being protected against the sprawl of towns and cities and other forms of development, noise carries into the parks from surrounding roads and planes flying overhead. The things built on the nanoscale are so impossibly tiny that sound vibrations will jiggle them around, making it hard to work on them. It uses sound-absorbing anechoic wedges which are fit into the chamber's walls, ceilings and door.


Not only did we fulfill the requirements they needed for their testing, but we were able to deliver a facility that set a new world record.
By all meaning, Sound does not exist in this room and the place is referred to as ‘noise-free’ labs.
Even the animals living in protected National Parks in the US are being exposed to chronic levels of noise.
Noise pollution can also effect the ability of many animals such as owls and bats to find and hunt their prey. In the Amazon, terrestrial insectivores, which also hunt using sound, especially avoid areas where roads are being constructed.
There are also anti-vibration mounts that help isolate the chamber from the rest of the building’s foundation.
Brownian motion (the random movement of particles in the air) is the quietest known sound outside the vacuum of space. These labs are being used by IBM to carry out its Nanotechnology research and is part of a $90 million research facility.The room’s architect, Dr. Writing in the journal Trends in Ecology and Evolution, three scientists based in Fort Collins, Colorado, US detail the extent to which noise pollution is now harming wild animals. Laboratory studies have shown that gleaning bats, which locate prey by the sounds they make, avoid hunting in noisy areas.
Systematic monitoring by the Natural Sounds Program, a research exercise carried out by the US National Park Service, confirms the extent of the noise intrusion. Emanuel Loertscher said that if you were to put your ear close to the wall of this room, your inner ear will ‘become unbalanced and you’ll feel dizzy and start vomiting.’ The sound is dampened to such a level for this room that it virtually doesn’t exist. Great tits (Parsus major) sing at higher frequencies in response to urban noise, so they are better able to hear each other. That can place gleaning bats at a higher risk of extinction, as noise pollution increasingly corrupts once habitable areas.
Noise is audible during more than one quarter of daylight hours at more than half of 55 sites in 14 National Parks studied to date.


In the US alone, between 1970 and 2007, the US population increased by approximately one-third. Well, we’ve already mentioned its part of their nanotechnology research facility and while working with the smallest technology on Earth has its perks, it also has its downside as well. Traffic on US roads tripled, to almost 5 trillion vehicle kilometres per year, while air traffic also more than tripled between 1981 and 2007, say the reviewers. When working on a nano-scale, even the sound vibrations are able to rattle the things around. Shipping noise has similarly increased, according to recent reviews of the effects that artificial noise has on marine mammals such as whales.

Hence, it could possibly hinder the production and therefore a sound proof lab was required for this purpose.IBM is making proper use of this room where they are busy making computer chips that are the size of human cells and also the world’s smallest movie which has atoms as actors in it.
