A study among British airline pilots shows that 20 percent of them have scores on a burnout scale that are comparable to those of people that are under burnout treatment. Surprisingly, the same study shows that only one of the 1147 pilots that participated, did not meet the performance standards at the regular flight simulator training. The authors argue that airline companies need to offer better support and facilities to their pilots to help them cope with their stressful jobs.
Children who get less than the recommended amount of sleep for their age are at a higher risk of developing obesity. Research at the University of Warwick has found that children and adolescents who regularly sleep less than others of the same age gain more weight when they grow older and are more likely to become overweight or obese.
Typically, when a soundwave strikes a surface, it reflects back at the same fundamental frequency with a different amplitude. A new model, reported in the Journal of Applied Physics, shows that when a sound wave hits a nonlinear elastic metasurface, the incident fundamental frequency does not bounce back. Instead, the metasurface converts that energy into the wave's second harmonic resonance. Developing this metasurface could help architects reduce noise from performance halls to cityscapes.
When falling asleep, relaxing or undertaking recreational activities, nearly a third of residents living near a wind farm are not at all annoyed or only slightly annoyed by the noise of wind turbines. One in ten people experience symptoms of stress. However, noise is not the only problem. In particular, a critical attitude towards a wind farm stimulates the experience of stress.A better information policy during the planning phase could help alleviate problems for residents.
A University of Texas at Arlington researcher is part of a team of authors who have found that using a mobile device at home for work purposes has negative implications for the employee's work life and also their spouse.
Millions of Americans hear ringing in their ears -- a condition called tinnitus -- but a new study shows an experimental device could help quiet the phantom sounds by targeting unruly nerve activity in the brain. Results of the first animal tests and clinical trial of the approach, which uses precisely timed sounds and weak electrical pulses that activate touch-sensitive nerves, resulted in a decrease in tinnitus loudness and improvement in tinnitus-related quality of life.
A new study is the first to identify a mechanism that could explain an early link between sound input and cognitive function, often called the 'Mozart effect.'
Spending a night in the hospital is not only stressful, but also loud. The constant beeps, whirrs and alarms ascend to a cacophony that produces anything but a relaxing, restful environment. Researchers will summarize the limited number of studies available on hospital noise and discuss the different approaches health care facilities are taking to bring restful repose to patients across the country during the 174th ASA Meeting, Dec. 4-8, 2017, in New Orleans, La.
Low-emission vehicles are considered too quiet for hearing-impaired pedestrians, so the European Union is mandating that they be equipped with acoustic vehicle alerting systems. With these alert systems would come a marked increase in the amount of noise on the roads across Europe. During the 174th ASA Meeting, Dec. 4-8, 2017, in New Orleans, researchers will present their work assessing the effectiveness of acoustic vehicle alerting systems and their downsides.
Want to restore hearing by injecting stem cells into the inner ear? Well, that can be a double-edged sword. Inner ear stem cells can be converted to auditory neurons that could reverse deafness, but the process can also make those cells divide too quickly, posing a cancer risk, according to a study led by Rutgers University-New Brunswick scientists.
