A new study found that pink noise can reduce restorative REM sleep and interfere with sleep recovery, while earplugs were more effective in protecting sleep against traffic noise. The findings challenge the widespread use of ambient sound machines and apps marketed as sleep aids.
Researchers found that adding audio to a moving subway scene increased balance challenges for people with vestibular problems. The study, published in PLOS ONE, suggests that sounds can be a disruptive factor for those with vestibular hypofunction, a condition resulting in impaired balance.
Researchers developed high-sensitivity and low-noise infrared superconducting nanowire single-photon detectors, achieving sub-mK temperature resolution. The detectors used photon counting technology, overcoming limitations of conventional semiconductor detectors.
A systematic review of 13 studies found that white and pink noise improved cognitive performance in children and young adults with ADHD, but had no effect on those without the condition. Researchers believe this could be a promising new tool to empower individuals with ADHD to live healthier and more productive lives.
Researchers designed a centered error entropy-based sigma-point Kalman Filter to enhance the filtering algorithm's robustness in spacecraft attitude determination. The proposed CEEUKF outperformed classical methods and other robust algorithms in simulating non-Gaussian noise, achieving higher accuracy and faster convergence rates.
The study found that visual pixel noise significantly improved reading skills and memory recall in children with major reading difficulties, particularly phonological impairments. The amount of white noise was critical for achieving these improvements, with moderate levels showing the most significant effects.
A new study found that traffic noise and man-made sounds significantly impact the mating choices of female field crickets. In noisy environments, females are unable to detect differences in male quality, leading to a reduction in offspring viability.
A Baylor University study found that college students who listened to classical music during a lecture and in their sleep performed better on a test the next day. However, over time, scores dropped to 'floor level' as performance averaged less than 25% for both groups.
Researchers from the University of Basel found that adding white noise to a quiet environment improves the brain's ability to distinguish subtle tone differences. This is achieved through reduced neuronal activity in the auditory cortex, allowing for more precise sound perception and potentially improving cochlear implant results.
Researchers at the University of Washington developed a smart speaker skill called BreathJunior that uses white noise to monitor infants' breathing and movement. The system detected respiratory rates closely matching those detected by standard vital sign monitors, showing promise as a tool for parents and hospitals.
The density and length of teeth on male bush-crickets' wings play a crucial role in altering the tone of their mating calls, with shorter files producing more musical calls and rigid files with higher tooth density producing lower tonal purity.
A new US study reveals that noise pollution is most prevalent in black neighborhoods and segregated cities, with a strong correlation between noise levels and race. The research found that neighborhoods with higher proportions of black residents had higher median night-time noise levels.
Scientists discovered that genetic material known as introns can play a dramatic role in plant gene activity. Introns act as volume control for some essential genes, making them silent when removed. This finding suggests that many genes may not have a traditional on/off switch.
A new report shows a 50% increase in speech comprehension in background noise after a three-week auditory training program for children with hearing impairments. The effect was still evident three months later, indicating the development of new hearing and listening strategies.
Scientists have created a blended scent, known as 'Laurax,' which spans the entire range of human olfaction and is perceived as neutral. This breakthrough challenges conventional wisdom on how our sense of smell works.
Researchers have discovered that thermal noise can cause unidirectional motion in nanoscale systems with asymmetric structures. By considering the finite autocorrelation time of thermal noise, they show that this effect is feasible even at room temperature.
Research by Northwestern University and Wake Forest University found that fast disclaimers undermine consumers' trust in unfamiliar brands, while trusted brands remain unaffected. Trusted brands can use fast disclaimers without impact on purchase intention.
A new study found that playing white noise in class can improve the memory of schoolchildren with difficulties in paying attention. The researchers discovered a significant improvement in performance for inattentive children and a decline in performance for attentive ones as noise levels increased.
Scientists have found that natural variation is a built-in mechanism to allow the nervous system to explore and maintain motor skills, even in highly practiced skills like those seen in top athletes and musicians. This discovery has implications for rehabilitating patients following strokes and other damage to the nervous system.
Researchers at Yale University found that playing a patient's favorite music during surgery reduces the need for sedatives. In contrast, using white noise or no headphones did not decrease sedative requirements. The study involved 36 patients at Yale-New Haven Hospital and 54 patients at the American University of Beirut Medical Center.
A recent study by the University of Michigan found that Blacks' environmental concerns equal or exceed those of whites, with greater concern about local pollution and poorer environmental quality. The survey of 793 people identified significant differences in environmental attitudes between Black and white neighborhoods.
Researchers at Boston University found that introducing background noise can enhance a person's ability to feel subtle stimuli. The study suggests potential applications for clinical treatment and developing tactile interfaces for telerobotics and virtual environments.
