Many individuals use music in the hope that it fights sleep difficulties, according to a study published Nov. 14 in the open-access journal PLOS ONE by Tabitha Trahan of the University of Sheffield, UK, and colleagues. As described by the authors, this is the first online survey on the use of music as a sleep aid in the general population.
One concern with the increase vessel transits in the western Canadian Arctic is how noise pollution can detrimentally affect marine animals. Researchers at the University of Victoria, WCS Canada and JASCO Applied Sciences have found that the negative impact of noise from shipping vessels can be mitigated by reducing the ship's speed. They will present their research at the Acoustical Society of America's 176th Meeting, Nov. 5-9.
Air pollution and transportation noise are both associated with an increased risk of heart attacks. Studies on air pollution, which do not take into account traffic noise, tend to overestimate the long-term effect of air pollution on heart attacks. These are the results of a study conducted by the Swiss Tropical and Public Health Institute, and published today in the European Heart Journal.
Male humpback whales reduce or cease their songs in reaction to human-generated shipping noise, according to a study published Oct. 24, 2018 in the open-access journal PLOS ONE by Koki Tsujii from Ogasawara Whale Watching Association and Hokkaido University, Japan, and colleagues.
Familiar voices are easier to understand and this advantage holds even if when we aren't able to identify who those familiar voices belong to, according to research in Psychological Science, a journal of the Association for Psychological Science.
Health costs associated with noise from changing flight patterns over populated urban landscapes far outweigh the benefits of reduced flight times, according to a new study. The researchers used flights from LaGuardia airport that have historically flown over Flushing Meadows and the US Tennis Center in Queens -- known as the TNNIS route -- as a case study to explore the trade-offs between more efficient flight routes and suffering on the ground.
A team from the University of Kansas has investigated the 'Speech-to-Song Illusion,' where a spoken phrase is repeated and begins to sound as if it were being sung.
Male bottlenose dolphins retain their individual 'names' well into adulthood. Similar to humans, this plays a central role in forming and maintaining complex social relationships, recent findings carried out by researchers at the universities of Zurich and Western Australia suggest. Dolphins form long-lasting alliances in which they give each other mutual support.
Wind turbines are a source of clean renewable energy, but some people who live nearby describe the shadow flicker, the audible sounds and the subaudible sound pressure levels as 'annoying.' They claim this nuisance negatively impacts their quality of life. Researchers in Canada set out to investigate how residential distance from the wind turbines affects people's health; they report their new analysis in the Journal of the Acoustical Society of America.
The preliminary results show that sounds of nature that were played in the fruit and vegetable section of a grocery shop had a clear impact on the shop's sales. The sales of fruit and vegetables showed an increase of 20 percent compared to the previous week and 13 percent compared to the week that followed.
